Louisiana CAR DMV Practice Test 7

If your power steering stops working, additional effort will be required to maintain steering control. Reduce your speed and pull off the roadway to stop in a safe area.

Use one-hand steering only when backing or when operating vehicle controls (wipers, flashers, lights, etc.) that require a temporary reach from the steering wheel.

A green steady arrow means you may pass through the intersection in the direction that the arrow is pointing. Oncoming traffic is required to stop for turning traffic.

Eight-sided traffic signs warn drivers that they must stop and yield the appropriate right-of-way at an intersection. Drivers may proceed when it is safe to do so.

White lines separate lanes of traffic that are moving in the same direction. Dashed white lines may be crossed to pass or change lanes, if it is safe to do so.

You should slow down at the first sign of rain, snow, or sleet, all of which can create slippery road conditions. When conditions on the road are less than ideal, safety may require that you drive more slowly than the posted speed limit.

Painted curbs indicate parking restrictions. When a curb is painted white, it indicates that only short stops are permitted.

Drowsiness can make people drive so poorly that they appear to be drunk. Opening a window, turning on the radio, or drinking coffee is not enough to make a drowsy driver alert to roadway hazards.

Stopping distances increase on wet or icy roads. Stopping distances also increase on road surfaces covered in loose gravel or stones.

In some metropolitan areas, traffic lights are horizontal instead of vertical. On these signals, the red light is on the left, the yellow light is in the middle, and the green light is on the right.

Special child seats are available for children who are too small to wear regular safety belts. No person is strong enough to safely hold onto a child of any size during an accident or sudden stop. Never allow a child to ride in a vehicle unless they are properly fastened into a seat.

Warning signs are normally diamond-shaped and yellow, although orange warning signs are used in work areas. Such signs warn that you are approaching a hazardous location or an area where special rules apply.

This sign warns that there is a steep hill or downgrade ahead.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This warning sign indicates that a traffic signal is ahead and drivers should prepare to react to a yellow or red light.

This sign warns that a road has one-way traffic and you must not enter from your current direction.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers that they are approaching a winding road and that they should adjust their speed accordingly.

Guide signs, sometimes known as destination signs, have a green background and provide directional and mileage information to specific destinations. They can be a helpful resource when driving in unfamiliar locations.

Yield the right-of-way to any approaching emergency vehicle that is using its flashing lights or siren, regardless of its direction of travel. You must immediately drive to the right side of the road and stop until the emergency vehicle has passed. If you are within an intersection, pass through the intersection before coming to a stop on the right side of the road.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers to be aware of potential traffic entering from an upcoming side road.

Most warning signs are diamond-shaped and yellow with black markings. These signs warn drivers about unexpected conditions that may not be readily apparent.

Make sure your tires are in proper condition before you enter your vehicle. A tire with low air pressure or poor tread can make driving unsafe.

Blind spots are areas around your vehicle that you cannot see with your mirrors. Check your blind spots by turning your head and looking over your shoulders.

The faster you drive, the greater the potential force of impact or striking power of your vehicle. When you double the speed of a car, you increase its force of impact by four times.

This sign warns that the road is slippery when wet.

When approaching an unmarked railroad crossing, slow down and be prepared to stop. Before you cross, be sure that no trains are approaching from either direction on any track. If you see or hear a train coming, stop at a safe distance from the nearest track and wait to proceed until after the train passes.

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

Two solid yellow lines down the center of a two-way road mean that neither lane of traffic may cross the lines, unless they are turning off of the roadway. A driver can cross double yellow lines when turning into or out of a driveway or entrance to a business. No passing is allowed over a solid yellow line.

Use hand-to-hand steering while driving normally at speeds above 15 mph. Hand-to-hand steering is also commonly called push/pull steering.

This sign warns that pavement is slippery when wet. In wet conditions, you should reduce your speed, avoid braking or changing direction suddenly, and increase the distance between your vehicle and the one ahead.

The faster you drive on a wet roadway, the less effective your tires will be at wiping the water from the road. If your speed becomes excessive enough, your tires will lose their grip on the road entirely and you will begin to hydroplane (that is, to slide down the road on a film of water).

Many people think you only need to use your parking brake when parking on a hill or if your car has a manual transmission. However, whether your car is a manual or automatic or whether the terrain is hilly or flat, you should use your parking brake every time you park.

Always stop before entering the roadway from a driveway and yield to any approaching vehicles or crossing pedestrians. The stop should be made before crossing the sidewalk area. Failure to stop is unlawful.

A roundabout is a circular intersection that usually does not include a traffic signal and flows in a counterclockwise direction around a central island. Motorists must enter from the right, yielding to traffic already in the roundabout, and follow the circle to the right until the desired roadway is reached.

This sign indicates that there is an intersection ahead. A road joins from the right.

A flashing yellow light at an intersection means "caution." If you approach such a light, slow down, look, and proceed with care.

When turning onto a street with more than one lane moving in the direction that you are traveling, turn into the lane that is closest to your previous lane. Do not change lanes when turning.

You must do everything you can to prevent striking a pedestrian or another vehicle, regardless of the circumstances. It is the driver’s basic responsibility to be alert to pedestrians and to yield the right-of-way to all pedestrians, even if the pedestrian is crossing the street where they should not be.

Because it is dark, drivers cannot see as well at night as they can during the day. From one half hour after sunset until one half hour before sunrise, or at any other time when persons or vehicles are not visible for 500 feet, drivers must use their headlights.

If a green arrow turns into a solid green light, you may still turn in the direction that the arrow was pointing but you must first yield to pedestrians and oncoming traffic.

Pedestrians should not enter a street or crosswalk when vehicles are approaching. Though pedestrians have the right-of-way in crosswalks, a vehicle approaching from a close distance may not have the time to stop before entering the crosswalk.
