Here’s something most Minnesotans don’t realize. You can drive your personal car without ever getting it inspected. Seriously.
Minnesota ditched mandatory vehicle inspections for regular passenger cars back in 1999. But before you breathe a sigh of relief, hold on. There’s more to this story.
Some vehicles still need inspections. Commercial trucks, buses, limousines. They all have different rules. And the penalties for breaking these rules can hit your wallet hard.
Let’s break down exactly what you need to know about inspection laws in Minnesota.
What Are Vehicle Inspections?
A vehicle inspection is a check-up for your car or truck. Think of it like a doctor’s appointment, but for vehicles.
Mechanics look at important parts during these inspections. Brakes, lights, tires, steering. They make sure everything works properly and safely.
Some states require these checks every year. Minnesota used to be one of them. Not anymore, at least not for regular cars.
The goal is simple. Keep unsafe vehicles off the road. Protect drivers, passengers, and everyone else sharing the highways.
Do Regular Cars Need Inspections in Minnesota?
Nope. If you drive a personal car, truck, or SUV, you’re off the hook.
Minnesota doesn’t require safety inspections for passenger vehicles. You also don’t need emissions testing. This changed in 1999 when the state ended its Vehicle Inspection Program.
Pretty straightforward, right?
But wait. Just because the state doesn’t require it doesn’t mean you should skip maintenance. Your brakes still need checking. Your tires still wear down. Your lights can burn out.
Smart drivers still get their vehicles checked regularly. It’s just not a legal requirement anymore.
Commercial Vehicle Inspection Requirements
Here’s where things get serious. Commercial vehicles face strict inspection rules.
Minnesota Statute 169.781 requires commercial motor vehicles to get inspected annually. They must display a valid inspection decal.
What Counts as a Commercial Vehicle?
Not sure if your vehicle qualifies? Let me break it down.
A commercial motor vehicle in Minnesota is:
A vehicle or combination of vehicles with a gross vehicle weight over 26,000 pounds. That’s basically any big truck.
Any vehicle that transports hazardous materials. If you need placards on your vehicle, you need an inspection.
Self-propelled special mobile equipment. This includes things mounted on commercial vehicle chassis weighing more than 26,000 pounds.
Vehicles used to transport passengers by motor carriers of railroad employees. Yep, that’s specific.
Basically, if you’re using a vehicle for business and it’s big or carries dangerous stuff, it needs an inspection.
Who Can Perform Commercial Inspections?
You can’t just take your commercial vehicle to any mechanic. Minnesota is picky about this.
Only certified inspectors can do the job. These include:
Employees of the Department of Public Safety who’ve been trained by the State Patrol. They know what they’re doing.
Employees of the Minnesota Department of Transportation. Same deal.
Certified private inspectors. These are owners or employees of commercial vehicle companies, licensed dealers, or repair shops that have gotten special certification.
The Minnesota State Patrol partners with technical colleges and the Minnesota Trucking Association. They offer certification courses for inspectors.
Want to become a certified inspector? You’ll need training. The 2025 Certified Inspector Student Handbook is available online.
What Gets Checked?
The inspection isn’t a quick once-over. It’s thorough.
Inspectors follow federal standards. Specifically, Code of Federal Regulations, title 49, section 396.17. That’s a mouthful, but it basically means they check everything that could cause an accident.
Brakes get inspected. All of them. Service brakes, parking brakes, trailer connections.
Steering mechanisms. Lights and reflectors. Tires. Windshield wipers. Seat belts.
The whole brake system gets attention. Master cylinder, shoes, linings, pads, drums, rotors, hoses, tubing. Everything.
Your horn better work. Your mirrors better not be broken. Your suspension needs to be in good shape.
If anything doesn’t meet federal motor carrier safety regulations, you won’t pass.
The Inspection Decal
Pass the inspection? You get a decal.
This decal shows the month the vehicle was inspected. It’s valid for 12 months from that month.
The decal costs up to $2. Not a huge expense.
Here’s the important part. You must display this decal on your commercial vehicle. No decal? That’s illegal.
Decals are issued by serial number. They’re not transferable unless the commissioner approves it.
Farm Vehicle Exemptions
Good news if you own a covered farm vehicle. You might not need an inspection.
A covered farm vehicle meets specific criteria. It displays a farm license plate. A farmer or family member or employee operates it.
It transports agricultural commodities, livestock, machinery, or farm supplies. Makes sense.
If the gross vehicle weight is 26,001 pounds or less, you can operate it anywhere in the United States without an inspection.
If it’s heavier than 26,001 pounds? You can still skip the inspection if you operate it within your state of registry. Or when crossing state lines, stay within 150 miles of your farm.
However, if requested by the owner, a certified inspector can still conduct an inspection. Some farmers prefer the peace of mind.
Special Transportation and Limousine Inspections
Drive a limousine or special transportation service vehicle? Different rules apply to you.
These inspections are handled by MnDOT, not just any certified inspector.
Limousine Requirements
Minnesota regulates limousine service under state law. Section 221.84 and Minnesota Rules chapter 8880 cover the details.
Every limousine needs an annual inspection. Only MnDOT Office of Freight and Commercial Vehicle Operations inspectors can do this.
The inspection costs $80. That’s more than a regular commercial vehicle decal.
What gets checked? Everything.
Brake systems. Lights. Mirrors. Interior cleanliness. Fire extinguisher. Emergency reflective triangles.
Limousines must comply with the manufacturer’s recommended maintenance schedule. That’s actually written into the rules.
Operators must keep inspection records. They need to be available at the principal place of business for three years.
Special Transportation Services
Special transportation services carry elderly people or individuals with disabilities. The rules are protective.
These vehicles also need annual inspections by MnDOT inspectors. The standards align with Commercial Vehicle Safety Alliance level 5 inspection procedures.
They check the same components as other vehicles. Plus wheelchair securement devices. Lifts and ramps. Emergency exits.
Safety is the priority here. These passengers are vulnerable.
School Bus Inspections
School buses have their own inspection system. The Minnesota State Patrol handles these.
Every school bus gets inspected annually. No exceptions.
Head Start buses also fall under this requirement. Any bus displaying a certificate under section 169.451 follows these rules.
These inspections are thorough. Probably more thorough than any other vehicle inspection in the state.
Why? Because we’re talking about children’s safety.
The inspection is free for the carrier. The State Patrol doesn’t charge for this service.
Daily Inspection Requirements for Commercial Vehicles
Annual inspections aren’t the only requirement. Drivers of commercial motor vehicles have daily responsibilities too.
Minnesota Statute 169.782 requires daily inspections. Every single day.
What the Daily Inspection Covers
The driver must inspect their commercial motor vehicle each day they operate it. This isn’t optional.
The inspection covers critical parts. Service brakes. Parking brake. Steering mechanism. Lights and reflectors. Tires. Horn. Windshield wipers. Mirrors. Emergency equipment.
No major defects found? Drivers of most commercial vehicles don’t need to submit a written report.
But passenger-carrying commercial motor vehicles are different. Those drivers must prepare and submit a written report every single day. Even if nothing is wrong.
Reporting Problems
Find a defect? The driver must report it.
The owner or their agent must review the report. If the defect affects safety, it needs fixing before the vehicle goes back on the road.
The owner must certify on the report that the defect was corrected. Or that correction is unnecessary.
These reports must be kept for at least three months. They need to be in the vehicle at all times.
State Patrol or Transportation Department representatives can review these records anytime. They can also conduct random inspections.
Exemptions from Daily Inspections
Some vehicles don’t need daily inspection reports. Farm trucks that can be operated without a commercial driver’s license get a pass.
Vehicles held for resale by licensed dealers also skip this requirement. Makes sense since they’re not being used commercially yet.
Covered farm vehicles without hazardous materials don’t need daily reports either.
Penalties for Violating Inspection Laws
Okay, this part is important. Read carefully.
Violating Minnesota’s inspection laws is a misdemeanor. That’s the baseline penalty.
Operating Without a Valid Inspection Decal
Drive a commercial motor vehicle without a valid inspection decal? That’s illegal.
The fine varies. But a misdemeanor in Minnesota can mean up to 90 days in jail. Or a fine of up to $1,000. Sometimes both.
Most first-time offenders won’t see jail time. But the fine can still hurt.
Fraudulent Inspection Decals
This one’s way more serious. With the intent to defraud, falsely making, duplicating, altering, or forging an inspection decal is a gross misdemeanor.
Possessing a fake decal with intent to defraud? Also a gross misdemeanor.
A gross misdemeanor in Minnesota means up to one year in jail. And a fine of up to $3,000.
That’s no joke.
Failing Daily Inspections
Driving a commercial motor vehicle without a copy of the required inspection report? Misdemeanor.
Again, up to 90 days in jail or a $1,000 fine.
It adds up fast if you’re not careful.
Certificate Suspension or Revocation
Certified inspectors face their own consequences. The commissioner can suspend a certificate for failing to meet annual certification requirements.
They can also suspend it for not following proper inspection procedures.
If the commissioner determines an inspector issued a decal for a vehicle that didn’t meet standards? That certificate gets revoked.
Revocation is permanent unless you go through the whole certification process again.
Post-Crash Inspections for Commercial Vehicles
Get in an accident with a commercial motor vehicle? More inspections might be required.
Minnesota Statute 169.783 covers this. Peace officers responding to certain accidents must notify the State Patrol immediately.
When Post-Crash Inspections Are Required
The law triggers when an accident results in:
A fatality. Obviously serious.
Bodily injury requiring immediate medical treatment away from the scene. If someone goes to the hospital, this applies.
Disabling damage requiring a tow. If vehicles can’t be driven away, inspection time.
The Post-Crash Inspection Process
After notification, a state trooper or authorized person inspects the commercial vehicle. They determine if it can safely be operated.
Until that inspection happens, driving the vehicle is a misdemeanor. You cannot move it.
The inspector can waive the requirement. They might do this if the inspection isn’t needed or would cause unreasonable delay.
If a waiver is granted, the inspector provides written documentation to the driver.
What Happened to Emissions Testing?
Minnesota used to require emissions testing. That program started in 1991.
The Twin Cities didn’t meet federal air quality standards back then. Carbon monoxide levels were too high.
So the state started the Minnesota Vehicle Inspection Program. It tested vehicles for emissions and pollutants.
Why It Ended
The program ended in 1999. The Minnesota Pollution Control Agency requested reclassification of the area’s air quality status from the federal government.
They got it. The testing stopped.
Minnesota hasn’t required emissions testing for passenger vehicles since then.
Honestly, this surprised me. Most people assume bigger cities still require this.
The Minnesota Pollution Control Agency does note that vehicle emissions are still a concern. The number of drivers, miles driven, and volume of emissions all increase each year.
But instead of testing, the agency focuses on other air pollution issues related to vehicles.
Should You Still Get Your Car Inspected?
Here’s my personal opinion. Even though it’s not required, getting your vehicle inspected is smart.
Why Optional Inspections Make Sense
Mechanics can catch problems early. That saves money in the long run.
Safety inspections reveal issues you might not notice. Worn brake pads. Failing suspension components. Electrical problems.
Minnesota weather is tough on vehicles. Extreme cold in winter. Heat in summer. Salt on the roads. All of this causes wear and tear.
An annual inspection helps spot potential safety hazards before they cause accidents.
What an Optional Inspection Includes
A good safety inspection covers key components. Brakes get checked thoroughly. All lights, including turn signals and reverse lights.
Tires get measured for tread depth. Windshield wipers get tested. Seat belts get examined for fraying.
Steering and suspension systems get evaluated. Mirrors get checked for damage.
Many shops perform these inspections for a reasonable fee. Some dealerships even offer them free with other services.
Emissions Checks
You can still get emissions testing even though it’s not required. Some shops offer this service.
Why would you? Maybe you want to do your part for the environment. Maybe you’re selling your car to someone in another state that requires testing.
Regular maintenance of your emission control system helps your car run efficiently. It can even improve gas mileage.
How to Find a Certified Inspector
Need to get your commercial vehicle inspected? Finding a certified inspector is your first step.
MnDOT Inspectors
The Minnesota Department of Transportation has inspectors at various locations. They handle special transportation services and limousine inspections.
You can schedule an inspection online. But only for the Metro vehicle inspection site in Richfield. Other locations require calling ahead.
The phone number for Commercial Vehicle Operations is 651-366-3700.
Private Certified Inspectors
Many private businesses have certified inspectors. Repair shops. Truck dealerships. Fleet maintenance companies.
Bona Bros is one example. They have ASE-trained technicians with experience inspecting thousands of vehicles.
Their technicians undergo continuous training by the Minnesota Department of Transportation. That’s important.
Look for a repair facility that’s certified for commercial vehicle inspections. They should display their certification prominently.
Costs for Private Inspections
Private inspectors can charge reasonable fees. What’s reasonable? It varies.
Most charge between $50 and $150 for a thorough inspection. That doesn’t include any repairs needed.
The actual decal costs up to $2. But the inspection service itself costs more.
Some fleet owners have five or more commercial vehicles. They can get testing equipment and facilities that meet requirements. Then they can inspect their own vehicles.
This saves money if you have a large fleet.
Keeping Inspection Records
Records matter. A lot.
What Records to Keep
Commercial vehicle owners must maintain vehicle files. Each file must contain vehicle identification information.
Company number if marked. Make, serial number, year, tire size. If the vehicle is leased, identify who furnished it.
Inspection records go in these files. Show the date and mileage of each inspection. List every component checked and any defects found.
Keep certifications showing defects were corrected. Include the name and address of who made the repairs.
How Long to Keep Records
Inspection records must be kept for at least three months. Some records need to be kept for three years.
Limousine operators must keep inspection records for three years. Special transportation services have the same requirement.
These records must be available at your principal place of business. The commissioner can request to inspect and copy them at any time.
State Patrol and Transportation Department employees can review records. They can also conduct random inspections and audits at your facility.
Don’t mess around with record-keeping. It’s not worth the penalty.
Out-of-State Vehicles
Moving to Minnesota from another state? Different rules apply temporarily.
Certificate of Compliance
Minnesota-registered commercial vehicles maintained in other states can apply for a certificate of compliance. This works if the vehicle has been inspected according to federal regulations.
All certificate of compliance requests get reviewed by Minnesota State Patrol inspectors. They don’t rubber-stamp these.
Interstate Commerce
Operating in interstate commerce? You might already meet federal inspection requirements.
Minnesota recognizes federal inspections. If your vehicle complies with federal standards, you can apply for proof of federal inspection.
This can substitute for the Minnesota annual inspection requirement. But you need documentation.
Tips for Passing Commercial Vehicle Inspections
Want to make sure your commercial vehicle passes? Prepare ahead.
Pre-Inspection Checklist
Check all lights before your appointment. Headlights, taillights, brake lights, turn signals. Make sure they all work.
Test your brakes. Do they grab evenly? Any pulling to one side? Get that fixed first.
Look at your tires. Tread depth matters. So does tire pressure. Check for uneven wear or damage.
Make sure your windshield wipers work. No cracks in the windshield that obstruct the driver’s view.
Test your horn. Sounds simple, but inspectors check it.
Maintenance Between Inspections
Don’t just maintain your vehicle right before inspection. Do it year-round.
Follow the manufacturer’s maintenance schedule. Change oil regularly. Rotate tires. Check fluid levels.
Keep your vehicle clean. Mud flaps and splash guards need to be in place. They must be at least as wide as the tire.
They should clear the ground by no more than nine inches. This prevents water and debris from splashing other vehicles.
Windows and mirrors need to be clean and uncracked. Your field of view cannot be obstructed.
Emergency Equipment
Make sure you have required emergency equipment. A properly filled fire extinguisher, securely mounted and accessible.
Minimum rating 5B:C or two 4B:C for general commodities. If you transport hazardous materials, you need a 10B:C rating.
Three red reflective warning devices for stopped vehicles. These are required.
Limousines need three bidirectional emergency reflective triangles. They must conform to federal motor vehicle safety standard 125.
Don’t wait until inspection day to check this stuff. Have it ready all the time.
What If Your Vehicle Fails Inspection?
So your vehicle didn’t pass. Now what?
Fixing the Problems
The inspector will give you a list of defects. These need to be corrected before you can get your decal.
Some problems are minor. A burned-out light. A loose mirror. Get those fixed quickly.
Other problems are bigger. Brake system issues. Steering problems. Suspension damage. These take time and money.
You cannot legally operate the vehicle until it passes inspection. This is serious.
Re-Inspection
After fixing the problems, schedule a re-inspection. Some inspectors don’t charge for the second check if you had the work done at their facility.
Others charge a re-inspection fee. Ask ahead of time.
For vehicles inspected by MnDOT, there’s no cost for re-checks by state staff. That’s helpful.
For private MIP inspections, a second inspection requires another fee. The decal itself costs another $2 too.
Timeline Considerations
Your inspection decal is only valid for 12 months. If it expires while you’re getting repairs done, that’s a problem.
Plan ahead. Get your inspection done with time to spare. Don’t wait until the last minute.
If you’re running a business with commercial vehicles, downtime costs money. Keep vehicles maintained so inspections go smoothly.
Common Inspection Mistakes to Avoid
People make the same mistakes repeatedly. Don’t be one of them.
Forgetting to Display the Decal
You passed inspection. Great. Now put the decal on your vehicle.
Sounds obvious, right? But some people forget. Or they put it in the wrong place.
The decal needs to be visible. Inspectors and law enforcement need to see it easily.
Using an Expired Decal
Decals are valid for 12 months from the month specified on the decal. After that, they’re worthless.
Operating with an expired decal is the same as operating without one. It’s illegal.
Mark your calendar. Set a reminder. Don’t let your inspection lapse.
Skipping Daily Inspections
Commercial drivers sometimes skip their daily inspections. Bad idea.
These inspections catch problems before they cause breakdowns or accidents. They’re required for a reason.
Take the few minutes each day to do it right. It could save your life.
Falsifying Records
Never, ever falsify inspection records. This includes decals and daily inspection reports.
The penalties are severe. Gross misdemeanors. Criminal charges. Loss of certification.
Your reputation gets destroyed. Your business could be shut down. It’s not worth it.

No. Minnesota does not require safety or emissions inspections for regular passenger cars. This has been the case since 1999 when the state ended its Vehicle Inspection Program.
What vehicles need annual inspections in Minnesota?
Commercial motor vehicles over 26,000 pounds require annual inspections. Vehicles transporting hazardous materials need inspections regardless of size. Limousines, special transportation services, and school buses also need annual inspections. Self-propelled special mobile equipment mounted on commercial vehicle chassis over 26,000 pounds requires inspection too.
How much does a commercial vehicle inspection cost in Minnesota?
The inspection decal costs up to $2. However, private certified inspectors can charge reasonable fees for their services, typically between $50 and $150. Limousine inspections by MnDOT cost $80. School bus inspections by the State Patrol are free.
What happens if I operate a commercial vehicle without a valid inspection decal?
Operating a commercial vehicle without a valid inspection decal is a misdemeanor in Minnesota. Penalties can include up to 90 days in jail or a fine of up to $1,000, or both. The vehicle cannot legally be operated until it passes inspection and displays a valid decal.
Can I inspect my own commercial vehicle?
Only if you’re a certified inspector. Owners or employees of commercial vehicle companies can become certified through training provided by the State Patrol or approved partners. Once certified, you can inspect vehicles you own or vehicles owned by your employer. The certification process requires training and testing.
Final Thoughts
Minnesota’s inspection laws are straightforward for most drivers. Regular passenger cars don’t need inspections. That’s convenient.
But if you drive a commercial vehicle, pay attention. The rules are strict. The penalties are real.
Get your annual inspections done on time. Keep up with daily inspections. Maintain proper records. Display your decals properly.
It’s not complicated, but it is important.
Stay safe out there. When in doubt about whether your vehicle needs an inspection, call MnDOT or check with a certified inspector. Better to ask than to face penalties later.
Now you know the basics of Minnesota inspection laws. You’ve got this.
