What Tourists Miss

Alabama school-zone speeding is charged at double fines during posted hours, and many counties use unmarked patrol cars on I-65 between Birmingham and Montgomery. Rental-car tourists get ticketed the most on US-231 around Dothan.

Driving in Alabama

Driving in Alabama (AL) means navigating hot, humid summers and mild winters. The state capital is Montgomery, and the road network ranges from busy urban freeways to remote rural two-lanes. Handheld phone use behind the wheel is banned.

Urban roads30 mph (48 km/h)
State highways55 mph (88 km/h)
Urban interstates65 mph (105 km/h)
Rural interstates70 mph (113 km/h)

Speed limits may vary by local ordinance. Some rural interstates posted at 70 mph.

School zones in Alabama drop to 15-25 mph when children are present, and construction zones often carry doubled fines. Watch for posted signs — local limits can vary from the defaults.

Traffic Laws in Alabama

Cell Phone Law: Hands-free required for all drivers. Texting while driving banned. Police in Alabama enforce this as a primary offence, meaning they can pull you over for this alone.

Seatbelt Law: Primary enforcement for front seat occupants. Both drivers and all passengers must be belted in Alabama.

Right Turn on Red: Permitted in Alabama after a complete stop, unless a sign says otherwise. Yield to pedestrians and cross traffic.

Move-Over Law: Alabama 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 when visibility is less than 500 feet.

Child Restraints: Children under 6 must be in a child restraint system. Children 6-14 must use a seatbelt.

DUI Laws in Alabama

The legal BAC limit in Alabama is 0.08% for drivers 21 and over. For drivers under 21, the limit is 0.02%. Commercial vehicle drivers face a nationwide 0.04% limit.

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

Tyre Requirements in Alabama

There is no winter tyre mandate in Alabama, though having season-appropriate tyres is strongly recommended. Not addressed by state law; rarely needed due to climate.

Studded Tyres: Prohibited year-round.

Tread Depth: Alabama enforces the federal minimum of 0.0625 inches (2/32"). At this depth, wet braking performance is severely compromised. Replace tyres at 4/32" — do not wait for the legal limit.

Heat and UV in Alabama 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 Alabama

Alabama requires all drivers to carry liability insurance. Keep proof in your vehicle. If you are stopped without it, penalties include fines and possible licence suspension.

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

Licence Requirements for Visitors to Alabama

Visitors from other US states can drive in Alabama 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.

New residents of Alabama must get a state licence after establishing residency. Requirements usually include a vision screening, a written test on Alabama’s traffic laws, and possibly a behind-the-wheel exam.

Toll Roads in Alabama

Toll facilities in Alabama increasingly use cashless electronic tolling. Rental cars may come with a transponder option, but the daily fee adds up quickly. Consider getting your own transponder if driving extensively in Alabama.

Seasonal Driving in Alabama

Driving conditions in Alabama are shaped by hot, humid summers and mild winters.

Key hazards in Alabama:

  • Heavy rain can cause flash flooding — never drive through standing water
  • Summer heat increases tyre blowout risk — check pressure before long drives
  • Check weather forecasts before travelling, especially during storm season
  • Keep an emergency kit: water, phone charger, first aid supplies, torch, and snacks

Renting a Car in Alabama

The minimum rental age in Alabama is typically 21, though drivers under 25 pay a surcharge. Some agencies rent to 18-20 year olds with an additional fee. International visitors should confirm that their licence and IDP are accepted by the agency.

Before leaving the lot in Alabama, photograph any existing damage, test the lights, wipers, and horn, and verify that the spare tyre and jack are present. Check the fuel policy — most agencies expect a full tank on return.

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

Emergency Contacts in Alabama

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

After a crash in Alabama: 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.

If your car breaks down in Alabama, pull off the road as far as safely possible, activate hazard lights, and set up reflective triangles if you have them. Stay in your vehicle on busy highways and call for assistance.

Driving Tips for Alabama

Tips to keep you safe on Alabama’s roads:

  • Follow posted limits. Alabama enforces speed limits, stop signs, and lane restrictions actively. Fines increase in school and construction zones.
  • Yield to pedestrians. Alabama law requires drivers to yield to pedestrians in crosswalks. Give cyclists at least three feet of clearance.
  • Signal your intentions. Use turn signals well before turning or changing lanes in Alabama.
  • Stay alert. Long drives across Alabama can be tiring. Stop every two hours or 100 miles to rest.
  • Wildlife hazard: deer on rural roads, especially during autumn.
  • School zones. Slow down in Alabama school zones during school hours. Passing a stopped school bus with flashing lights is a serious offence in every US state.
