Getting pulled over in South Carolina is stressful. Not knowing the law makes it worse. Whether you just moved here or you’ve been driving these roads for years, there are some important updates you need to know about.
This guide covers the key driving laws in South Carolina for 2026. We’ll keep it simple and straight to the point.
What Are South Carolina’s Driving Laws?
South Carolina’s driving laws are the rules that every driver must follow on public roads. They cover speed limits, phone use, seatbelts, drunk driving, and more. These laws exist to keep everyone safe.
Honestly, some of these rules have changed recently. And if you haven’t kept up, you could get a ticket without even realizing you broke a law.
Speed Limits in South Carolina
Speed limits in South Carolina depend on where you’re driving. The rules are pretty clear once you know them.
On interstate highways and freeways, the maximum speed is 70 mph. On multilane divided highways, you’re limited to 60 mph. On regular roads and other locations, the limit drops to 55 mph. Unpaved roads have a maximum of 40 mph.
Wondering if you can ever go faster? Nope. These are the absolute maximums. You still need to slow down more in bad weather, heavy traffic, or near school zones.
South Carolina also has a basic speed rule. You must drive at a speed that is safe for current conditions. Even if the posted limit is 70 mph, driving that fast in a storm could still get you a ticket.
South Carolina’s New Hands-Free Phone Law
Okay, this one is important. Pay close attention.
South Carolina passed a brand-new hands-free driving law. It took effect on September 1, 2025. Fines started on March 1, 2026.
The law bans holding your phone while driving. You cannot hold or physically support your phone with any part of your body. You also cannot read texts, write texts, or watch videos while driving.
So simple! Just put the phone down.
You’re allowed to use your phone hands-free. Bluetooth, earpieces, and voice commands are all fine. You can also use Apple CarPlay or Android Auto through your car’s system, as long as you’re not physically holding the device.
Here’s where it gets interesting. Other devices are covered too. Laptops, gaming consoles, and other electronics are also banned while driving. GPS units built into your car are still okay.
There are a few exceptions. You can use your phone if you are legally parked or stopped. You can also use it to report an emergency or accident. First responders are exempt while on duty.
What if you get caught? A first offense costs you $100. A second offense within three years costs $200, plus two points on your license. Those points can raise your insurance rates.
Seatbelt Laws in South Carolina
Seatbelt enforcement in South Carolina is primary. That means officers can pull you over just for not wearing one. They don’t need another reason.
All passengers must wear a seatbelt. Drivers are responsible for making sure passengers 17 and under are buckled up. The fine for a seatbelt violation is $25.
For kids, the rules are stricter. Children aged 2 to 4 must ride in a forward-facing car seat in the back. Kids aged 4 to 8 must use a booster seat in the back. Once a child is 8 years old or at least 57 inches tall, a regular seatbelt works if it fits properly.
Most people don’t realize how strict these car seat rules are. Don’t find out the hard way.
DUI Laws in South Carolina
Let’s talk about the penalties for driving under the influence. Now, here’s where things get serious.
In South Carolina, it is illegal to drive with a blood alcohol concentration (BAC) of 0.08% or higher. For drivers under 21, the limit is just 0.02%. That’s basically zero tolerance for young drivers.
Hold on, this part is important. South Carolina has a 10-year lookback period. That means any DUI conviction in the past 10 years counts against you. Even if you got your first DUI nine years ago, a new one is treated as a second offense.
First Offense DUI
A first DUI with a BAC under 0.10% comes with a fine of up to $400 and up to 30 days in jail. Your license is suspended for six months. You also must complete an Alcohol and Drug Safety Action Program, known as ADSAP.
If your BAC was between 0.10% and 0.16%, the fine goes up to $500. A BAC of 0.16% or higher means a $1,000 fine and at least 30 days in jail.
Second Offense DUI
A second offense is much more serious. Fines range from $2,100 to over $6,500 depending on your BAC. Jail time runs from 5 days up to 3 years. Your license is suspended for one year.
Third and Fourth Offenses
By a third offense, jail time can reach 3 years. Fines can top $10,000. Your license can be revoked for four years if the offense is within five years of your first DUI.
A fourth DUI in South Carolina is a felony. You could face 1 to 5 years in prison and a permanent license revocation. That’s not a traffic ticket. That’s life-changing.
Ignition Interlock Devices
Think of it like a breathalyzer for your car. As of 2024, South Carolina requires all DUI offenders, even first-timers, to install an ignition interlock device before getting their license back. This device tests your breath before the car will start. You pay for it yourself.
Refusing a Breath Test
Many people think refusing the breathalyzer is a smart move. It’s not. South Carolina has an implied consent law. By driving here, you’ve already agreed to be tested if arrested. Refusing gets your license suspended for 6 months on the first refusal. It goes up from there.
Felony DUI in South Carolina
Wait, it gets more serious. A regular DUI can become a felony charge under certain conditions.
If you cause great bodily injury while driving drunk, that is felony DUI. The fine is $5,100 to $10,100, and you face up to 15 years in prison. If someone dies, prison time jumps to 1 to 25 years. Those are consequences that follow you forever.
Personally, I think these penalties make sense. Drunk driving kills people. The law treats it accordingly.
Driving Without a License
Not having a valid license is also against the law. South Carolina is actually considering increased penalties for this offense in 2026, with legislation moving through the state legislature.
Under current law, a first offense for driving without a license is a fine of $10 to $100 or up to 30 days in jail. A charge can be dismissed if you prove you had a valid license at the time of the stop.
Driving on a suspended license is even more serious. A first offense there brings a fine of $300 or up to 30 days in jail. A third offense jumps to a $1,000 fine and up to 3 years in prison. Plus, your suspension gets extended by the same amount of time.
Speed and Reckless Driving
Speeding is one of the most common violations. But reckless driving is a whole different level of trouble.
Reckless driving means driving with willful or wanton disregard for the safety of others. Think street racing, weaving through traffic at high speeds, or running red lights intentionally. This is a criminal offense, not just a traffic ticket.
Accumulating 12 or more points on your license can get it suspended. Speeding adds points. Reckless driving adds more. Running a red light adds points too. It adds up faster than you’d expect.
Fleeing from Police
This one’s worth mentioning. Trying to run from a police officer is a serious crime in South Carolina.
Failing to stop when signaled by police is a misdemeanor on the first offense. You face up to 3 years in jail and a 30-day license suspension. A second offense becomes a felony with up to 5 years in prison.
Here’s where it gets worse. If you led officers on a high-speed chase that was recorded on camera, that’s an automatic felony. Mandatory minimum of 3 years in prison. No exceptions.
How to Drive Legally in South Carolina
You’re not alone if this feels like a lot. Let me break down what you need to do to stay legal on the road.
First, always carry your valid license, registration, and proof of insurance. Second, keep your phone in a mount or use Bluetooth. Do not hold it while driving. Third, buckle up every single time. Make sure all passengers are buckled too. Fourth, never get behind the wheel after drinking. Call a rideshare or ask someone for a ride.
If you have a teen driver at home, know the rules for learners permits. South Carolina allows learner’s permits starting at age 15. The permit must be held for at least 180 days before getting a conditional license. Young drivers have restrictions on passengers and driving hours.
Don’t worry, you don’t have to memorize all of this today. Just keep these basics in mind and you’ll be in good shape.
