Alabama DMV Practice Test 21

Warning signs are usually yellow with black markings. This sign warns drivers that the upcoming road will curve right, followed by a curve to the left. Drivers should adjust their speed to safely continue on the road.

Before changing lanes, signal, look in all your mirrors, and look over your left or right shoulder to make sure the lane next to you is clear. Looking over your shoulder is a way to check your blind spot to be sure there is no vehicle, motorcycle, or bicycle traffic in the next lane.

You must approach all railroad crossings with extreme caution and cross only when you know that no train is coming from either direction. Be aware of vehicles that must stop at all railroad crossings, such as school buses and trucks carrying hazardous materials.

A flashing yellow traffic light means drivers must slow down, be more aware, and proceed with caution. Be alert to crossing traffic and pedestrians.

Yellow lines separate lanes of traffic moving in opposite directions. A broken yellow line next to your driving lane means that you may pass.

After coming to a full stop, vehicles should proceed through a four-way stop in the order in which they arrive to the intersection. If multiple vehicles arrive at the same time, the vehicle on the left must yield the right-of-way to the vehicle on the right.

Drivers must slow down when approaching an intersection. If a clear view of cross traffic is obscured, a driver should come to a stop and inch forward until they can see clearly in both directions.

Yellow lines mark the center of a road used for two-way traffic. A solid yellow centerline indicates that drivers may not cross the line to pass. A broken yellow centerline indicates that drivers may cross the line to pass, but only if passing would not interfere with traffic.

A reflective orange triangle on the rear of a vehicle means it travels only at slow speeds. You may see this sign on roadwork equipment, farm vehicles, or horse-drawn wagons and carriages. It appears as a solid orange triangle during the day and a hollow red triangle at night.

You should enter a freeway at or near the speed of traffic, unless the speed of traffic exceeds the legal speed limit.

If multiple vehicles arrive at the same time to an intersection that is not controlled by signs or signals, the driver on the right has the right-of-way. Drivers should then proceed in the order that they arrive to the intersection.

You must not pass a vehicle that is stopped at a crosswalk. There may be pedestrians crossing the street that you cannot see. Instead, stop, proceeding only after all pedestrians have crossed.

You may not know what is on the other side of a hill or just around a curve, even if you have driven the road many times. If a vehicle is stalled just out of sight on the roadway, you must be able to stop. Whenever you come to a hill or curve, adjust your speed so you can stop if necessary.

Driving too slowly can be dangerous because it may cause drivers behind you to become frustrated and make dangerous moves to pass you. It is safest to drive with the flow of traffic, within the legal speed limit.

Lane usage for the motorcyclist is critical. Motorcycles are entitled to the same full lane width as all other vehicles.

As driving speeds increase, the chance of a fatality in the case of a collision increases. If you are going faster than 80 miles per hour, you have almost no chance of living through a crash. The speed you drive affects your stopping distance, so you should increase your following distance as you increase your speed.

It is important to remember that driving is a privilege and that all drivers play a role in ensuring that everyone remains safe on the roadways. If you prove to be abusive of that privilege, the privilege may be revoked.

When entering a roundabout, you must yield to pedestrians, bicyclists, and traffic already in the roundabout.

If you experience a tire blowout, you should slow down gradually by taking your foot off of the accelerator. Don’t apply the brakes until the vehicle has slowed considerably.

Before changing lanes, it is very important to check behind you. You should look over your shoulder to ensure that you are not getting in the way of vehicles in the lane you want to enter. Before changing lanes, you should also ensure that no drivers are attempting to drive into the same spot from a different lane.

When approaching this sign, you must yield the right-of-way. Slow down and let vehicles and pedestrians crossing your path pass before you proceed. If necessary, stop before going ahead.

Increase your following distance when it is difficult to see due to darkness. Use headlights to increase visibility, following the rules for proper use of high beams and low beams. Avoid looking directly at the headlights of an oncoming vehicle to avoid being blinded by the glare.

Develop a routine for entering and leaving your car. Before switching on the ignition, buckle your safety belt and see that all passengers do likewise.

You should always signal when moving your vehicle to the right or left. On an interstate, you should stay in the right lane if you are moving more slowly than the surrounding traffic. It is illegal to back up or make a U-turn on interstate highways, so if you miss your exit, you should proceed to the next exit.

While it can create special problems for large vehicles, strong wind can cause problems for all drivers. Wind can lower visibility by blowing dirt and dust into the roadway, but it can sometimes also physically move a vehicle.

It is necessary to follow farther behind a large truck than you would if following a passenger vehicle because trucks have larger blind spots.

If your vehicle begins to skid, release the accelerator or brake pedal to regain vehicle balance. Steer in the direction of the skid to regain control of the vehicle.

When driving in a work zone, adjust your speed for the traffic conditions and don’t follow other vehicles too closely. Be attentive to workers and machines in the work zone.

When a school bus is flashing its red lights and has its stop arm extended, motorists must come to a full stop until the lights are turned off, the stop arm is withdrawn, and the bus begins moving again.

Always be aware of what is happening around your vehicle. Constantly observing your surroundings to the front, sides, and rear of your vehicle will help you see problems that may require you to change speed or roadway position.

On cold, wet days, shaded spots on a roadway can become icy. Shaded areas often freeze before, and thaw out after, the rest of a road.

As you enter a work zone, signs and message boards will warn you of workers, slow-moving equipment, and/or closed lanes ahead. You should reduce your speed and be prepared to slow down or stop.

Legal medications, both prescription and over-the-counter, can impair your ability to drive. They can be particularly dangerous when used in combination with alcohol.

A five-sided sign is used to alert drivers to a school zone. Some pentagonal signs specifically indicate crosswalks within school zones where children or other pedestrians may be present.

Pedestrians who use guide dogs or white canes (with or without a red tip) must be given the right-of-way at all times.

Hydroplaning occurs when there is standing water on a roadway. At speeds up to 35 mph, most tires will channel water away from the tire. As your speed increases past 35 mph, tires cannot channel the water as well and your tires may start to lose contact with the road and ride over the water like a set of water skis.

Holding a driver license is not a right. It is a privilege that must be earned and maintained.

A round sign means you are approaching a railroad crossing. This sign is posted a few hundred feet in front of the tracks and tells drivers to slow down, look, listen, and prepare to stop.

An eight-sided red sign means “stop.”

Orange warning signs are used in and around work zones. Use special caution when you see orange signs, cones, or barriers on a roadway.
