Alabama CAR DMV Practice Test 3

Being under the influence of alcohol affects your judgment. Good judgement is necessary to react appropriately to things that you see or hear while on the road. Even if you are below the legal blood alcohol limit, consuming any amount of alcohol is likely to affect your ability to drive safely.

This sign warns of the possible presence of merging traffic.

Downward-facing triangular signs mean drivers must yield. When approaching a yield sign, slow down to a speed that is reasonable for existing conditions and stop if necessary. If you must stop, do so at a marked stop line, if it exists.

If you are going to back up a vehicle, it is a good practice to first walk around the vehicle to be sure no person or obstacle is behind it. Before backing, you should look to the front, sides, and rear and continue to look over your right shoulder to the rear while backing. Do not depend only on your mirrors.

When driving in a work zone, keep a safe distance between your vehicle and traffic barriers, trucks, construction equipment, workers, and other vehicles. Increase your following distance and do not tailgate.

Warning signs are usually yellow with black markings. This sign indicates that the road ahead will turn sharply to the right and then sharply to the left.

The only way to remove the impairing effects of alcohol is to give the body time to remove it from the body. Drinking coffee, physical activity, or taking a cold shower will not speed up this process. It takes about one hour to cancel the effects of one drink.

An eight-sided red sign means "stop."

When you are approaching a school bus that has stopped on the road with its stop signal arm extended and its red lights flashing, come to a complete stop. Remain stopped until the stop signal is retracted and the flashing lights are turned off.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

When parking downhill, turn your front wheels toward the curb or edge of the road. When parking uphill on a road without a curb, turn your wheels toward the edge of the road. When parking uphill on a road with a curb, you must turn your front wheels away from the curb.

This sign warns that there is a flag person ahead. Always follow directions given by a flagger. Flaggers normally wear orange or yellow vests, yellow-green shirts, or bright jackets. They use paddles and red flags to direct traffic through the work zone and to let workers or construction vehicles cross the road.

When driving in an urban district, the statutory speed limit is 30 miles per hour. If a different speed limit is posted, follow the posted speed limit.

A warning sign is usually yellow with black markings. This sign warns that the number of lanes ahead is reduced and that traffic will need to merge to the left.

This sign marks the presence of a crosswalk. Be alert to any pedestrians that may be crossing the roadway.

A truck's blind spots are much larger than a smaller car’s blind spots. The driver cannot see your car behind their vehicle and you can't see what’s happening in traffic ahead if you're driving too closely behind the truck. Whether you are driving behind or to the side of the truck, if you can’t see the driver’s face in their side view mirror, then they can’t see you.

If possible, try to only deal with one roadway hazard at a time. If you want to pass a pedestrian but an oncoming vehicle is approaching, slow down and let the vehicle pass. You may then pass the pedestrian if it is safe to do so.

Where there are both solid and dashed yellow lines between lanes of traffic, only traffic directly next to the dashed line may cross the centerline to pass. Drivers next to the solid line may not pass.

Night driving creates a unique set of problems for drivers. Due to the reduced visibility, it can be difficult to judge distance and the traveling speeds of other vehicles when driving at night. Drivers can see only as far as their headlights allow.

Before changing lanes, check for drivers trying to pass you who may be trying to enter the same lane as you. Look over your shoulder to check your blind spot. You should never attempt to pass or otherwise change lanes in an intersection.

At an intersection controlled by a steady yellow light, you should bring your vehicle to a safe stop. If you are already within the intersection when the light changes from green to yellow, continue through the intersection at a safe speed.

A five-sided sign indicates that you are near a school. Be aware and stop if children are in the crosswalk.

When stopped for a traffic violation or at an equipment check, a driver must produce their license, proof of registration, and proof of insurance. Drivers are required to have all three of these documents in a vehicle when it is being driven.

This sign prohibits right turns. You cannot make a right turn at an intersection where this sign is posted.

You may drive more slowly than the posted speed limit, based on road conditions, but it is illegal to drive any faster than the posted speed limit. Some conditions which require reduced speed for safety include approaching curves or hills where visibility is limited, driving on slippery roads, and driving on roads where animals and pedestrians are present.

When approaching a school bus that is picking up or dropping off passengers, you must come to a complete stop before reaching the bus, regardless of your direction of travel.

Pentagonal signs mean you are approaching a school zone and/or school crossing. When you see these signs, be alert and prepare to stop.

A red arrow means "stop." You must remain stopped until a green light or green arrow appears. Do not turn against a red arrow.

Stop when a traffic signal is red. Remain stopped at a steady red light until the signal changes to green.

When making a left turn, you must yield to pedestrians, bicyclists, or other vehicles moving on their green light.

When passing another vehicle that is traveling in the same direction as you, pass quickly to resume visibility. Return to your previous lane only when you can see both of the vehicle's headlights in your rearview mirror.

Your emotions affect your ability to drive safely. If you are overly angry, excited, afraid, worried, or depressed, you should give yourself time to calm down before operating a vehicle. You need to be able to mentally focus on driving without thinking about the things that made you upset.

When driving, do not develop a fixed stare. Frequently check your rearview mirrors so you know the positions of vehicles near you.

This sign warns of a dangerous downgrade or hill ahead. The hill may be very long or steep, or it may have sharp curves.

Backing up is always dangerous because it is hard to see behind your vehicle. Use extra caution when backing up.

Pedestrians have the right-of-way at street crossings but must obey traffic control signals. Where a traffic signal is not present, vehicles must stop for pedestrians in a crosswalk, whether it is marked or unmarked.

Although the right-of-way rules provide a guide to determine who should yield the right-of-way at an intersection, no one should assume they automatically have the right-of-way. The situation and circumstances at an intersection must always be considered. Drivers should yield their legal right-of-way if it can help prevent a collision.

You must stop at a railroad crossing if the gate is lowering. It is unsafe to do otherwise.

This sign indicates that U-turns are prohibited. You may see a sign like this at an intersection that commonly has oncoming traffic.

Fatigue causes errors related to speed and distance, increases your risk of being in a crash, and causes you to take more time to make decisions. When you are fatigued, you could fall asleep behind the wheel and crash, injuring or killing yourself or others.
