Alabama uses 25 mph as the default for business and residential areas and 65 mph on rural interstates. The permit knowledge test is 30 questions; you need a 80% to pass. Key rules that trip people up: Alabama requires headlights any time visibility drops below 500 feet, the DUI limit is 0.08% for adults and 0.02% for drivers under 21, and the Move Over law requires reducing speed when approaching any stopped emergency vehicle on a highway.
What is the speed limit in an urban district in Alabama, and what happens if no sign is posted? Speed limits are set by state law; when no sign is visible, these statutory limits apply:
| Location | Default Speed Limit |
|---|---|
| Urban district streets | 30 mph |
| Unpaved roads | 35 mph |
| County paved roads (unless posted) | 45 mph |
| Other locations | 55 mph |
| Interstate highways (where posted) | 70 mph |
| School zones (when active) | As posted, indicated on lighted sign with flashing amber lights |
Key test point: Speed limits are the maximum under ideal conditions. You must slow down in rain, fog, heavy traffic, or at night even if you are under the posted limit. This is called the Basic Speed Law.

When must you dim your high beams in Alabama, and how far away does an oncoming car need to be? Alabama law specifies exact distances for dimming, and the 500/200-foot rule is one of the most tested questions on the exam.
| Rule | Detail |
|---|---|
| When to use headlights | From a half-hour after sunset to a half-hour before sunrise, and any time visibility is less than 500 feet due to rain, fog, snow, or dust |
| Wipers = headlights | Alabama law requires headlights on whenever windshield wipers are in use due to rain, sleet, or snow (intermittent use exempt) |
| High beams, illumination range | On open roads with no oncoming traffic and no vehicle directly ahead; illuminates roadway approximately 350 feet under normal conditions |
| Dim to low beams, oncoming traffic | Switch to low beams when within 500 feet of an oncoming vehicle |
| Dim to low beams, following | Switch to low beams when within 200 feet of a vehicle you are following |
| Low beams in fog | Always use low beams in fog, high beams reflect off fog and reduce your visibility |
| Parking lights only | Not a substitute for headlights, illegal to drive using parking lights only |
Key test point: The 500-foot / 200-foot rule is a classic exam question. Oncoming = 500 feet. Following = 200 feet. Dim accordingly.
What does "overdriving your headlights" mean in Alabama, and why is it dangerous? Driving at night significantly increases crash risk; these rules cover visibility, speed, and wildlife hazards specific to Alabama roads.
| Rule | Detail |
|---|---|
| Overdriving your headlights | Never drive so fast that you cannot stop within the distance your headlights illuminate, this is called overdriving your headlights and is a major cause of night crashes |
| Reduce speed at night | Even at the posted limit, reduced visibility means you need more time to react, slow down |
| Increase following distance | Use a minimum 4-second following distance at night instead of the standard 3 seconds |
| Watch for pedestrians & cyclists | They are much harder to see at night, especially away from lit areas |
| Avoid looking directly at oncoming lights | Look toward the right edge of the road to avoid being blinded by oncoming high beams |
| Stay alert for wildlife | Deer and other animals are most active at dawn and dusk, especially on rural Alabama highways through the Black Belt and Appalachian foothills |
| Keep windshield clean | A dirty windshield causes glare at night and significantly reduces visibility |
Is it legal to use your phone while driving in Alabama, and can a cop pull you over just for texting? Alabama prohibits using a wireless device to write, send, or read a text message while operating a motor vehicle, with stricter expectations for all drivers.
| Rule | Detail |
|---|---|
| Texting while driving | Illegal for ALL drivers in Alabama, no exceptions. Officers can pull you over solely for texting. |
| Handheld cell phone use | When using a cell phone while driving, always prioritize driving. Use hands-free, speaker, or speed dial; place calls when stopped if possible. |

| Penalty, third or subsequent offense | Fine of $75 plus 2 points on driving record per offense |
| Other distractions | Eating, grooming, adjusting GPS, or anything that takes your eyes off the road can be cited as inattentive driving |
| Hands-free use | Bluetooth and hands-free devices are legal and recommended for all drivers |
Key test point: Texting while driving is prohibited in Alabama, police do not need another reason to pull you over. This distinction frequently appears on the knowledge exam.
How far from the tracks must you stop at a railroad crossing in Alabama, and what vehicles must always stop even when no train is coming? Alabama ranks #13 in the nation for highway-railroad crossing fatalities; know exactly when to stop and how far back.
| Rule | Detail |
|---|---|
| When to stop | Stop when lights are flashing, gates are lowering or down, a train is visible or audible, or a flagman signals you to stop |
| How far back to stop | At least 15 feet from the nearest rail, never stop on the tracks |
| When to proceed | Only after the train has completely passed, lights have stopped flashing, and gates are fully raised |
| Multiple tracks | After one train passes, check for a second train on adjacent tracks before proceeding |
| Never race a train | Trains cannot stop quickly, a freight train at 55 mph takes a mile or more to stop (the length of 18 football fields). Never try to beat a train. |
| Stalled vehicle on tracks | Get everyone out immediately and move away from the tracks at an angle in the direction the train is coming from |
| Parking near crossings | Do not park within 50 feet of a railroad crossing |
Key test point: Never drive around or under a lowered crossing gate, it is illegal and extremely dangerous. Wait until gates are fully raised and all tracks are clear.
Who has the right-of-way in a roundabout in Alabama, and which direction do you drive? Roundabouts are increasingly common across Alabama and appear on the knowledge exam; the most missed question is about who yields when entering.
| Rule | Detail |
|---|---|
| Who has right-of-way | Vehicles already inside the roundabout always have right-of-way. Entering drivers must yield. |
| Direction of travel | Always travel counterclockwise (to the right) around the central island |
| Entering a roundabout | Slow down, yield to circulating traffic, and enter when there is a safe gap |
| Lane selection, single lane | Follow the directional signs and road markings for your intended exit |
| Lane selection, multi-lane | Choose your lane before entering based on your exit: right lane for right/straight exits, left lane for left turns or U-turns |
| Do not stop inside | Never stop inside a roundabout unless to avoid a collision, keep moving at a slow, steady speed |
| Large vehicles | Trucks and buses may use the mountable apron (raised inner ring) to navigate, give them extra space |
| Pedestrians & cyclists | Yield to pedestrians in crosswalks when entering and exiting. Watch for cyclists who may ride through the roundabout. |
Key test point: The most common wrong answer on roundabout questions is thinking you have right-of-way when entering. You never do, yield to traffic already inside.
"The AI mock tests were surprisingly realistic. The explanations for road signs helped me understand the logic, not just memorize. Passed my permit test on the first try!"
