Rules of the Road and Traffic Laws

  • Right-of-way at an uncontrolled intersection: the vehicle on the left yields to the vehicle on the right.

  • At a four-way stop, vehicles proceed in the order they arrived; if two arrive simultaneously, the one on the right goes first.

  • A left turn across oncoming traffic requires yielding to all oncoming vehicles until a safe gap exists.

  • Alabama speed limits: 30 mph in urban/residential areas, 55 mph on rural two-lane roads, 65 mph on rural interstates, 70 mph on some rural interstates where posted; always obey posted signs.

  • Following distance rule: use the three-second rule in ideal conditions; increase to four or more seconds in rain, at night, or behind large vehicles.

  • A driver must stop for a school bus with flashing red lights and extended stop arm when traveling in either direction on an undivided road.

  • Passing is prohibited on the left when a solid yellow line is on your side, within 100 feet of an intersection, or at a railroad crossing.

  • When an emergency vehicle approaches with sirens and flashing lights, pull to the right edge of the road and stop until it passes.

  • Alabama's Move Over law requires drivers to change lanes or slow down when passing stopped emergency, tow, or utility vehicles with flashing lights.

Traffic Signs, Signals, and Road Markings

  • Sign shapes carry meaning: octagon = stop, inverted triangle = yield, diamond = warning, pentagon = school zone, round = railroad advance warning.

  • Sign colors: red = stop/prohibition, yellow = warning, white = regulatory, orange = construction, green = guide, blue = services, brown = recreation.

  • A flashing red signal requires a complete stop, then proceed when safe, like a stop sign.

  • A flashing yellow signal means slow down and proceed with caution; no stop is required unless traffic dictates.

  • A solid yellow center line marks two-way traffic; passing is allowed only if the yellow line is on your side and it is safe.

  • A double solid yellow line means no passing in either direction.

  • A broken white line separates lanes of traffic moving in the same direction; lane changes are permitted when safe.

  • A solid white line marks the right edge of the roadway or a shoulder; crossing it is discouraged except in emergencies.

  • A green arrow means you may proceed in the direction of the arrow if the way is clear; a red arrow means stop and do not turn.

Safe Driving Practices and Hazard Awareness

  • Total stopping distance = perception distance + reaction distance + braking distance; at 60 mph it can exceed 300 feet on dry pavement.

  • Hydroplaning occurs when tires ride on a film of water; it can begin at speeds as low as 35 mph on wet roads.

  • In fog, use low-beam headlights; high beams reflect off the moisture and reduce visibility.

  • The Smith System: Aim high in steering, Get the big picture, Keep your eyes moving, Leave yourself an out, Make sure they see you.

  • When a tire blows out, grip the wheel firmly, ease off the accelerator, and steer straight; do not brake hard.

  • If your vehicle begins to skid, steer in the direction you want the front of the vehicle to go and avoid hard braking.

  • Alabama law requires headlights on from sunset to sunrise and whenever visibility is less than 500 feet.

  • A railroad crossing with no gates or lights requires slowing down, looking both ways, and listening before crossing.

  • Work zone speed limits are doubled in fines when workers are present; obey posted reduced speeds.

  • Alabama's legal blood alcohol concentration (BAC) limit is 0.08% for drivers 21 and older.

  • For drivers under 21, Alabama enforces a zero-tolerance policy: any BAC of 0.02% or higher is illegal.

  • A commercial driver's license holder is considered impaired at a BAC of 0.04%.

  • Implied consent law: by driving in Alabama, you consent to a chemical test if lawfully arrested for DUI; refusal can result in license suspension.

  • A first DUI conviction in Alabama carries up to 1 year in jail, fines up to $2,100, and license suspension.
