Traffic Laws in Mississippi

Cell Phone Law: No statewide handheld ban. Texting while driving banned for all drivers. Police in Mississippi enforce this as a primary offence, meaning they can pull you over for this alone.

Right Turn on Red: Legal in Mississippi after stopping fully. Check for “No Turn on Red” signs at individual intersections.

Move-Over Law: Mississippi requires drivers to change lanes or reduce speed when passing stopped emergency vehicles, tow trucks, or maintenance vehicles.

Headlights: Required from sunset to sunrise and during inclement weather conditions.

Child Restraints: Children under 4 must be in a child restraint system. Children 4-6 (under 4 feet 9 inches or under 65 lbs) must use a booster seat. Children 7 and older must use a seatbelt.

Penalties in Mississippi for a first DUI include fines, possible jail time, licence suspension, and alcohol education. Mississippi participates in the Interstate Driver’s License Compact, so a conviction here follows you to your home state.

Tyre Requirements in Mississippi

Mississippi does not mandate winter tyres, but appropriate tyres for the conditions are always your responsibility. Not applicable due to climate. No state law addressing tire chains.

Studded Tyres: Prohibited year-round.

Minimum Tread Depth: The legal minimum in Mississippi is 0.0625 inches (2/32"), the federal floor across all US states. Tyre experts recommend replacing at 4/32" for adequate wet-weather grip. At 2/32", stopping distance on a wet road at 60 mph is dangerously long.

Heat and UV in Mississippi age tyres faster than in cooler states. Replace tyres older than 5-6 years regardless of tread remaining. Check pressure when tyres are cold — heat expansion can mask under-inflation.

Insurance and Equipment in Mississippi

Liability insurance is mandatory in Mississippi. Carry proof of insurance at all times — driving without it in Mississippi can result in fines, licence suspension, and vehicle impoundment.

Required vehicle equipment in Mississippi: functioning headlights, brake lights, turn signals, at least one rearview mirror, a horn, windshield wipers, and valid registration plates. Check Mississippi’s specific window tint limits before adding aftermarket tint.

Licence Requirements for Visitors to Mississippi

Visitors from other US states can drive in Mississippi with their valid home state licence. International visitors should carry both their home licence and an International Driving Permit (IDP) obtained before travelling. The IDP is a translation, not a replacement — carry both documents.

If you relocate to Mississippi, you will need to obtain a Mississippi driver’s licence within the state’s residency grace period. This typically involves a vision test, written knowledge test, and sometimes a road test.

Toll Roads in Mississippi

Mississippi has no toll roads. All highways and interstates are free to use.

Seasonal Driving in Mississippi

Mississippi has hot, humid summers and mild winters. This directly affects when and how you should drive.

Seasonal tips for Mississippi:

• Sudden downpours reduce visibility to near zero — pull over and wait if needed
• High pavement temperatures cause mirages and tyre stress
• Always carry extra water in the vehicle, especially in summer
• Check Mississippi’s DOT website for real-time road condition updates before long trips

Renting a Car in Mississippi

Most rental agencies in Mississippi require drivers to be at least 21. Under-25 surcharges are standard. If you hold a foreign licence, bring your IDP and confirm acceptance when booking.

Inspect the rental car thoroughly before driving away. Document scratches and dents with photos. Familiarise yourself with the controls — headlights, wipers, hazard lights — before you leave the lot. Confirm the fuel type (most US rental cars use regular unleaded gasoline).

Check whether your personal auto insurance or credit card covers rental cars in Mississippi. International visitors without US coverage should purchase the agency’s liability and collision options.

Emergency Contacts in Mississippi

Dial 911 for any emergency in Mississippi — police, fire, or medical. For non-emergency roadside assistance, contact the Mississippi State Police.

After a crash in Mississippi: stop, call 911 for injuries, move out of traffic if possible, exchange information with the other driver, take photos, and file a police report if required. Never admit liability at the scene.

For breakdowns in Mississippi: move to the shoulder, turn on hazards, and call roadside assistance or 911. On high-speed roads, staying inside the vehicle is safer than standing outside it.
