License Plate Laws in Colorado (2026): Rules That Catch Drivers Off Guard

Most people think they know the license plate rules. You mount it on your car and you’re good to go, right? Not exactly. Colorado has some strict requirements that surprise a lot of drivers. The penalties can hit harder than you’d expect too.

Let’s break down what you actually need to know.

What Are License Plate Laws?

License plate laws tell you how to display, mount, and maintain your plates. They exist so cops can identify vehicles quickly. These rules help with safety and law enforcement.

In Colorado, these laws cover everything. Where you mount your plates matters. How clean they are matters. Even the covers you use can get you ticketed.

Pretty straightforward stuff, honestly.

Do You Need Two License Plates in Colorado?

Here’s where it gets interesting. Colorado is a two-plate state. That means you need a front plate AND a rear plate on most vehicles.

Yep, both.

A lot of people don’t realize this until they get pulled over. Some cars look better without a front plate. I get it. But Colorado doesn’t care about aesthetics.

There are exceptions though. Motorcycles only need one rear plate. Same goes for trailers, semitrailers, and street rod vehicles. Autocycles also get the one-plate treatment.

Semi-tractors are different. They need one plate on the FRONT.

Wondering if your vehicle is exempt? Check with your county motor vehicle office if you’re not sure.

How to Mount Your License Plates Correctly

Okay, this part is important. You can’t just slap your plates on anywhere. Colorado has specific rules about placement and mounting.

Rear Plate Requirements

Your rear plate must be horizontal. It needs to sit at least 12 inches from the ground. Measure from the bottom of the plate.

The plate should be in the approximate center of your vehicle. Stay within 18 inches of the rear bumper.

Keep it fastened securely. A swinging plate will get you pulled over.

Front Plate Requirements

The front plate also needs to be horizontal. Mount it in the location the manufacturer designed for it.

Most newer vehicles have a spot for this. Older cars might need a bracket installed.

Registration Stickers

You need current registration stickers on your rear plate. The month sticker goes in the bottom left corner. The year sticker goes in the bottom right corner.

These stickers must be visible at all times.

License Plate Covers and Frames

Hold on, this part is tricky. You CAN use license plate frames in Colorado. You CAN also use clear covers.

But here’s the catch. They cannot obstruct any part of your plate number. They cannot hide your registration tabs either.

Tinted covers are illegal. Smoked covers are illegal. Any cover that distorts the view from different angles breaks the law.

The law specifically bans devices that make your plate unreadable by automatic identification systems. Think red light cameras and license plate readers.

Clear covers are fine as long as they stay crystal clear. Once they get scratched or dirty enough to block the view, they become illegal.

Frames from dealerships? Totally legal. Just make sure they don’t cover any numbers or letters.

What About Dirty Plates?

You could face a ticket if your plate is covered in mud or snow. Seriously. Part of being a responsible driver means keeping your plates clean and visible.

When you’re clearing snow from your windshield, don’t forget about your plates.

Penalties for License Plate Violations

Most license plate violations in Colorado are Class B traffic infractions. These are civil matters, not criminal.

A Class B infraction carries a fine between $15 and $100. No jail time. No points on your license for most violations.

But wait, there’s more to know.

Higher Penalties for Certain Violations

Using a cover or device that makes your plate unreadable by automatic systems is more serious. This violation is a Class A traffic infraction.

The fine? Exactly $100.

This applies to tinted covers, smoked covers, and anything that alters the color or visibility of your plate.

What About Insurance?

Traffic violations can affect your insurance rates. Insurance companies view plate violations as risk indicators.

A history of these violations might increase your monthly premiums. Keep your record clean to avoid those extra costs.

Special Circumstances and Exceptions

Colorado has some unique rules you should know about.

Military Vehicles

Military vehicle owners have an option. You can choose not to display your license plate on the vehicle. But the plate must be inside the vehicle and available for inspection.

If a peace officer asks to see it, you need to have it ready.

Electric Vehicles

Plug-in electric and hybrid electric vehicles get special plates. You must either accept the Electric Vehicle license plate or get a Plug-In Electric Vehicle decal.

There’s no additional fee for the electric vehicle plate. Personalized versions cost $60 upfront plus $25 annually.

This requirement started in recent years to help identify electric vehicles.

Personalized Plates

Personalized plates cost more but follow the same display rules. You pay a one-time $60 fee. Then $25 each year when you renew.

The state reviews all personalized plate requests. They can reject anything offensive. If three people complain about your personalized plate, the state can revoke it.

What to Do If Your Plate Is Lost or Stolen

Lost your license plate? Don’t panic. Here’s what you need to do.

Report It

If your plate was stolen, report it to local law enforcement first. Get a case ID number. This is required before you can get a replacement.

For lost plates, you can skip the police report.

Complete the Affidavit

Download and complete Form DR 2283. This is the Affidavit for Lost or Stolen License Plates/Permits.

You can find this form on the Colorado DMV website.

Visit Your County Office

Bring the completed affidavit to your county motor vehicle office. You’ll need to pay a replacement fee. The cost varies by county and plate type.

Some counties let you order replacements online through myDMV.

Important Warning

If you choose to get the same plate number reissued, be careful. Your plate will still show as stolen in law enforcement databases for a while.

You risk being pulled over, stopped, questioned, or detained. Consider getting a new plate number instead.

How License Plate Laws Are Enforced

Police officers can pull you over for license plate violations. These stops are legal and happen regularly.

Here are the most common reasons drivers get ticketed:

Missing Front Plate

This is probably the most common violation. Lots of people don’t realize they need a front plate.

The fine ranges from $15 to $100.

Swinging Plates

If your plate isn’t fastened securely, you can get pulled over. Plates must be mounted to prevent swinging.

Pretty easy to fix, honestly.

Obstructed Plates

Dirty plates, tinted covers, or frames blocking your numbers all count as obstructions. Keep your plates clean and visible.

Snow and mud need to be cleared off.

No Registration Stickers

Expired or missing registration stickers will get you pulled over. Make sure your stickers are current and visible.

Replace them within one month of expiration.

Plates Not Illuminated at Night

Your rear plate must be lit at night. Most newer vehicles have built-in lights for this.

If the light burns out, you can get ticketed. Check it occasionally.

Plates Too Low

Your rear plate must be at least 12 inches from the ground. Lowered vehicles sometimes violate this rule.

Measure from the bottom of the plate.

Replacing Damaged or Faded Plates

Plates wear out over time. If yours is damaged, faded, or illegible, you need to replace it.

Visit your county motor vehicle office or use myDMV online. You’ll need your vehicle registration details and payment.

Standard plates can often be replaced immediately at county offices. Personalized and specialty plates take longer. They get printed and mailed to you.

Expect 2-6 weeks for delivery through USPS.

Recent Changes to License Plate Laws

Colorado updated some mounting requirements in 2018. Senate Bill 18-028 changed the rules.

The old law required plates to be centered and at least 12 inches from the ground. The new law keeps the height requirement but loosened the centering rule slightly.

Front plates must now be mounted horizontally in the manufacturer’s designated location. This gave drivers a bit more flexibility.

In 2021, Senate Bill 21-069 changed when plates expire. License plates now expire when you transfer ownership of your vehicle.

Personalized plates are the exception. You can keep those through ownership changes.

Tips for Staying Compliant

Want to avoid tickets? Here’s what I recommend.

Install Both Plates

Get that front plate mounted. Yeah, it might not look as cool. But it’s worth avoiding the hassle of a ticket.

Check Your Mounting Height

Grab a tape measure. Make sure your rear plate sits at least 12 inches from the ground.

Keep Plates Clean

Wash your plates when you wash your car. Remove snow and mud regularly.

This is such a simple thing, but lots of people forget.

Use Clear Covers Only

If you want a plate cover, make sure it’s completely clear. No tint, no smoke, no scratches that block the view.

Honestly, you might be better off without a cover at all.

Update Your Address

You must notify your county motor vehicle office within one month of changing your address. Same goes for name changes.

This keeps your registration current.

Renew On Time

Renew your registration within one month of the expiration date. Your stickers need to be current.

Set a reminder on your phone.
