Louisiana CAR DMV Practice Test 12

You should avoid making any sudden changes in speed or direction when driving on a slippery surface. Reduce your speed on slippery roads and do not use cruise control.

Keep right when another driver begins to pass you on the left. Check for oncoming traffic and adjust your speed to let the passing vehicle move back into the right lane as easily as possible.

When driving near a blind pedestrian who is carrying a white cane or walking with a guide dog, you must slow down, yield the right-of-way, and then proceed with caution. Be prepared to stop your vehicle in order to prevent injury or danger to the pedestrian.

The slow-moving vehicle symbol is a reflective orange triangle. Expect vehicles using this emblem to be driving at speeds of 25 mph or slower.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. Wherever this regulation sign is posted, U-turns are not permitted.

Tractor-trailers take longer distances to stop than smaller cars traveling at the same speed. A fully loaded tractor-trailer may take almost 400 feet to come to a complete stop when driving at 55 mph.

Yellow lines are used in the center of the road to separate lanes of traffic moving in opposite directions.

A stop sign means that you must come to a full stop and yield the right-of-way to vehicles and pedestrians in or heading toward the intersection. Go again when it is safe.

Regulatory signs require drivers to obey an indicated instruction. Failure to comply is subject to penalty.

Signs providing information about destinations are green with white letters or symbols.

This sign indicates that you are approaching a railroad crossing.

Being fatigued while driving is similar in danger to driving under the influence of alcohol. If you begin to feel tired while driving, the best thing to do is to stop driving.

Even the smallest amount of alcohol will reduce your concentration, perception, judgment and memory, and your driving skills will suffer. No one can drink and drive safely.

If your vehicle breaks down on the highway, you should signal before carefully exiting the roadway and turning on your hazard flashers. Get as far off the road as possible and park in a location where other drivers can easily see you. Lift your hood to let other drivers know your vehicle is disabled.

This sign indicates a low ground railroad crossing. Where this sign is present, railroad tracks cross the road at a steep slope and the bottom of low vehicles may drag or get caught on the tracks.

You cannot enter an intersection if traffic is backed up on the other side and you cannot get completely through the intersection. Wait until traffic ahead clears so you do not block the intersection.

At night, your field of vision is reduced. To make sure you are able to react to hazards on the roadway, always use appropriate headlights. Drive slowly enough that you are able to stop within the distance that you can see ahead.

You are required to stop at all railroad crossings when signals warn of an approaching train. These signals may include flashing red lights, a lowered crossing gate, a flagger signaling, or a train’s audible signal of warning. Do not attempt to go around a lowered gate.

Driving at night is more dangerous than driving during the day for several reasons. It is harder to see in the dark, you may be temporarily blinded by the glare from other vehicles' lights, and there are likely to be more drivers on the road who are tired or under the influence.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

Painted curbs indicate parking restrictions. When a curb is painted blue, it indicates a handicap parking restriction.

Do not exceed the school zone speed limit during indicated times. The end of a reduced speed school zone will be indicated by an "End school zone" regulatory sign.

A solid red arrow in a traffic signal means the same thing as a circular red traffic light. When an arrow is red, traffic in the indicated lane must stop and may not turn in the direction that the arrow is pointing.

When exiting a highway, you should get into the exit lane well in advance. Do not begin to slow down until after you have moved into the exit lane.

When parallel parking, your vehicle should be 18 inches from the curb or closer. Always park in a place that is visible to drivers coming from both directions.

Before changing lanes, check your side and rearview mirrors for traffic approaching you from behind. Just before you begin moving into the other lane, quickly glance over your shoulder and check for any vehicles that may be in your blind spot.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

This sign indicates that the road ahead curves to the right.

Yellow lines separate traffic moving in opposite directions. A single dashed yellow line in the center of a road indicates that vehicles traveling in both directions are permitted to pass. Drivers may only begin a pass if they will not interfere with any oncoming traffic.

When driving near a blind pedestrian who is carrying a white cane or walking with a guide dog, you must slow down, yield the right-of-way, and then proceed with caution. Be prepared to stop your vehicle in order to prevent injury or danger to the pedestrian.

Each time you pass another vehicle, there is an increased chance for a collision. If you are moving faster than surrounding traffic, you will have to continue passing others. Drive with the flow of traffic, within the legal speed limit, and pass only as needed.

As speeds increase, much less steering input is needed to move the vehicle to the left or right. Additionally, when anti-lock brakes are engaged or your vehicle is forced off the roadway, it may be necessary to limit your steering input to avoid moving out of your lane of travel and into other lanes of travel. Do not overcorrect, especially when driving at high speeds.

If you are being followed by an emergency vehicle that is not using its siren or flashing lights, you do not need to clear a path. Continue driving in a normal manner.

You should never start a left turn until you can see that all the lanes you need to cross are clear and that you can safely make the turn.

Any defect that may affect the safe operation of a vehicle should be corrected as soon as possible. Defects should be corrected before the vehicle is driven.

This sign warns drivers that the divided highway ends ahead.

You must stop when approaching a school bus that is displaying flashing red lights while stopped to pick up or drop off children. On a two-lane road, traffic moving in both directions must stop and remain stopped as long as the red lights near the top of the bus are flashing and/or the stop arm on the left side of the bus is extended.

When turning, look as far ahead as possible in the direction you want to go. You’ll have more time to react if there’s an obstacle ahead and the process of turning will be much smoother.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that parking is not permitted.

This sign indicates that there is a sharp right turn ahead.
