Alabama CAR DMV Practice Test 12

Never assume other drivers will give you the right-of-way. Yield your right-of-way whenever it helps prevent collisions.

If you notice that the road ahead is covered by heavy smoke, reduce your speed immediately, drive as far as possible to the right, and stop off the roadway. Only then should you determine if it is safe for you to continue. Remember that certain kinds of smoke can irritate your eyes and lungs or even kill you.

You must stop at a railroad crossing where signs, warning devices, or flaggers warn you of the presence of a train. It is illegal to drive around lowered gates.

Because large trucks require more time to accelerate than smaller vehicles, trucks can lose speed driving up long or steep hills. Be cautious when driving behind a large truck and be sure to give the vehicle additional space, especially when driving on an incline.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign indicates that there is a steep hill ahead. Slow down and be ready to shift to a lower gear to control your speed and protect your brakes from damage.

If you see an emergency vehicle approaching while using its flashing lights, pull over to the right edge of the road and stop. Position yourself parallel to the curb. On one-way streets, drive toward the road edge nearest you.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign tells drivers to be alert to crossing pedestrians.

A single broken line indicates that drivers may cross from either lane to change lanes. Dashed yellow lines alongside solid yellow lines indicate that passing is permitted from the lane next to the broken line, but not from the lane next to the solid line. Only change lanes when it is safe to do so.

You should adjust your speed to travel smoothly with the other traffic on a roadway (provided that the other traffic is driving within the posted speed limits). Remember that vehicles moving in the same direction at the same speed cannot hit each other. Crashes involving multiple vehicles often happen when some vehicles are traveling at different speeds than others.

A round yellow sign indicates that there is a railroad crossing ahead.

If your vehicle is hit from the rear while you are in forward motion, your body will be thrown backward. Brace yourself by pressing against the back of your seat and putting your head against the head restraint to prevent whiplash. Maintain a firm grip on the steering wheel and be ready to apply your brakes to avoid being pushed into another vehicle.

All roads are slippery and dangerous when wet. This sign warns of conditions that can cause a driver to lose control of a car. A driver should slow down when coming upon wet pavement because it takes longer to stop.

Before beginning a right turn, use the appropriate signal to give surrounding drivers adequate notice of your intentions. Slow down and approach the intersection from the right lane, staying as close as is practical to the right curb or edge of the roadway.

Yellow lines separating lanes of traffic indicate that traffic is moving in opposite directions. Double solid lines indicate that passing is not permitted from either direction.

Even if the signal is green, you must not enter an intersection unless you can get completely across before the light turns red. If you block the intersection, you can be cited.

Regulatory signs provide notice to road users of traffic laws that must be obeyed. This particular sign tells you the maximum speed limit for the stretch of highway where it 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.

You should be extra careful when turning and stopping during the first half hour of rain. At this point, the oil from cars has not yet washed off the pavement and could be forming a slippery mixture with the rain.

Drivers turning left must yield to oncoming vehicles that are driving straight ahead. A turning driver may only proceed when they can safely turn without affecting oncoming traffic.

Pennant-shaped yellow signs like this are used to indicate a no passing zone.

Bicycles do not have turn signals so bicyclists use hand and arm signals to alert other drivers to their intentions. If a bicyclist puts their left arm straight out, they are signaling that they intend to turn left.

At a green light, you must give the right-of-way to any vehicle, bicyclist, or pedestrian in the intersection. If a pedestrian begins crossing the street after the traffic signal light starts flashing, wait until they have crossed the street before proceeding.

Alcohol takes effect quickly and is slow to leave your system. Cold showers, black coffee, and exercise will do nothing to reduce a person's blood alcohol content (BAC). The only way to lower your BAC is to wait.

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.

Warning signs are usually yellow with black markings. This sign indicates that there is a steep hill ahead. Slow down and be ready to shift to a lower gear to control your speed and protect your brakes from damage.

This sign indicates that you are approaching a railroad crossing. You must look, listen, slow down, and prepare to stop. Wait for any trains to pass before you proceed.

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.

In foggy or misty conditions, you should not use your headlights on their high beam setting because the light will be reflected back into your eyes.

This sign informs drivers that they are leaving a divided roadway and approaching a two-way highway.

While waiting to turn left, keep your wheels pointed straight ahead until it is safe to start your turn. If a vehicle hits you from behind, this will prevent you from veering into oncoming traffic. When parked facing either uphill or downhill, turn the wheels so the vehicle will not roll into traffic if the brakes fail.

If your vehicle has a two-part seat belt system, be sure to wear both the lap belt and the shoulder belt. Wearing either part alone greatly reduces your protection. If you have an automatic shoulder belt, be sure to buckle your lap belt as well.

Regulatory signs provide notice to road users of traffic laws that must be obeyed. This sign tells drivers that it is prohibited to make a U-turn.

This sign warns that two lanes of traffic going the same direction will soon merge into one lane.

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

This sign alerts you to the possibility of traffic merging into the main stream of travel. After checking to your side and rear, you should move into another lane, if possible, to allow merging motorists a clear path.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This warning sign tells drivers to be alert to an intersecting side road ahead.

This sign indicates that the road may be slippery when wet. Exercise caution when driving on a slippery road.

There is zero tolerance for alcohol use by drivers under age 21. If you are under 21, the detection of any trace of alcohol in your system will result in stiff penalties, including the suspension of your license for two years.

The stop sign is the only eight-sided sign you will see on any roadway. When you encounter a stop sign, you must come to a complete stop. You may not proceed until the way is clear for you to completely and safely pass through the intersection.

Work zones on highways have become increasingly dangerous places for both workers and drivers. When approaching a work zone, watch for materials such as cones, barrels, signs, large vehicles, and workers in brightly colored vests to warn you and direct you.

A green arrow means "go." You must turn in the direction the arrow is pointing after you yield to any vehicles, bicycles, or pedestrians who are still in the intersection.
