The Nashville Banner reports that in the first quarter of 2025, the Metro Nashville Police made 11,496 traffic stops. That’s about 3,000 more stops than during the same period last year.

Although these numbers reflect enforcement in Tennessee’s capital, they show what’s happening across the state. Many of these stops happen when police suspect a traffic violation.

If found guilty, you could face fines, license points, or jail. That’s why knowing Tennessee driving laws is necessary.

The knowledge can help you avoid penalties, drive safely, and protect others. Here are the important driving laws in Tennessee you need to know before you drive.

License Requirements in TN

First-time drivers must pass:

  • A vision test
  • A knowledge exam
  • A road test
  • A traffic signs test
  • A written safety rules assessment

If you’re under 18, you must complete Tennessee’s Graduated Driver License program, which includes learner, intermediate restricted, and intermediate unrestricted phases. To learn how to drive, choose a reputable school such as Brentwood Driver Training. At BDT, we focus on safety and create a calm, supportive learning environment to ensure your success.

Seat Belt and Child Safety Seat Requirements

Tennessee law requires all drivers and passengers to wear seat belts. Front-seat occupants must buckle up, and failure to do so can result in a fine. Backseat passengers under 18 must also wear seat belts.

Children must ride in age-appropriate safety seats. Infants must be in rear-facing seats until at least age one and 20 pounds.

Older children must use booster seats until they are big enough to use a seat belt properly. These vehicle laws in Tennessee exist to save lives, especially in the event of an unexpected collision.

Speed Limits and Road Sign Awareness

A post by the Tennessee Highway Safety Office, citing TITAN, reveals that nearly 23,000 speeding-related crashes occurred in Tennessee from 2017 to 2019. Learning the speed limits in different places can help you stay safe and avoid violations, especially in areas like:

  • Rural interstates
  • Residential neighborhoods
  • School zones
  • Construction zones
  • City streets
  • Sharp curves

Road signs often display the speed limit and alert you to changes ahead. Paying attention to them helps you adjust your speed in time. Observing the speed limit supports driving safety and lowers your risk of accidents or legal trouble.

Distracted Driving Laws: Focus Behind the Wheel

Under Tennessee traffic rules, using a handheld phone while driving is illegal. The state’s Hands-Free Law bans drivers from:

  • Holding a phone while driving
  • Texting while the vehicle is in motion
  • Watching videos on a device
  • Recording or broadcasting videos
  • Reaching for a device in a way that takes you out of your seat position

You can only use a phone through a hands-free system like Bluetooth or speaker mode. Drivers under 18 face stricter limits–they cannot use a phone at all, even hands-free.

Using earbuds or headphones in both ears is also banned for all drivers. These laws aim to reduce distractions, which are a major cause of crashes. Staying focused behind the wheel helps protect lives and prevents legal trouble.

DUI Laws: Zero Tolerance for Impaired Driving

In Tennessee, drivers are considered legally impaired if their Blood Alcohol Content (BAC) reaches 0.08% or above. The legal limit is 0.04% for commercial drivers and 0.02% for drivers under 21.

Penalties for a DUI conviction can include:

  • Jail time
  • Heavy fines
  • Community service
  • License suspension
  • Mandatory alcohol education programs
  • Installation of an ignition interlock device

Taking driving lessons can help you better understand the risks of impaired driving and how to avoid them. Knowing the rules can protect your future and keep the roads safe for everyone.

Insurance Requirements and Proof of Financial Responsibility

You must carry auto insurance to drive legally in Tennessee. Your policy must meet the state’s minimum coverage requirements for injury and property damage.

If you’re pulled over or involved in an accident, you must show proof of insurance. Failing to do so can lead to fines, license suspension, and other penalties. High-risk drivers may also need to file an SR-22 form.

To lower your insurance costs, consider bundling policies, maintaining a clean driving record, and comparing quotes from different providers. Following Tennessee driving laws about insurance helps protect your finances and shows that you are a responsible driver.

Move Over Law and Emergency Vehicles

Tennessee has a Move Over Law that requires drivers to switch lanes when approaching emergency or service vehicles with flashing lights. If changing lanes isn’t safe, you must slow down significantly to protect those working on the roadside.

The law applies to:

  • Police vehicles
  • Fire trucks
  • Ambulances
  • Utility trucks
  • Tow trucks
  • Highway maintenance vehicles

Failing to follow this law can result in fines and license points. It is not just about avoiding penalties; it is about valuing the lives of those who serve and protect. Following driving safety laws helps prevent avoidable roadside tragedies.

Vehicle Equipment Rules: Keep Your Car Roadworthy

To drive legally in Tennessee, your vehicle must be in good working condition and meet safety requirements. The following parts must function properly to meet safety standards, especially in poor visibility:

  • Headlights and taillights
  • Brake lights
  • Windshield wipers
  • Turn signals
  • Horn
  • Tires with good tread

Although emissions testing is no longer required statewide, some counties still enforce it. Check the rules in your area to stay compliant. Modified vehicles must also meet noise and height limits.

Failing to follow these rules can result in fines or failed inspections. Following vehicle laws in Tennessee keeps your car safe, legal, and ready for the road at all times.
