Louisiana CAR DMV Practice Test 14

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers turning left at a green light must yield to oncoming traffic and may complete the turn when it is safe to do so.

Road rage is a criminal offense. If a minor traffic incident escalates into a far more serious situation, the drivers involved may face legal repercussions.

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.

Crosswalk lines show pedestrians where to safely cross a road or street. Crosswalks may be marked by horizontal lines, vertical lines, or a combination of the two. You must always stop for pedestrians who are in a crosswalk.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers should keep right to avoid an upcoming potential driving hazard.

Hurricane evacuation route signs indicate that a highway is an emergency evacuation route. You should know where these signs are in case an emergency strikes.

The diagonal stripes on a barricade or vertical panel guide drivers in the proper direction. Stripes sloping downward and to the right mean drivers should bear to the right. Conversely, stripes sloping downward and to the left mean they should bear to the left.

If your vehicle begins to skid, remain calm. Steer in the direction that you want to go and try not to overcorrect.

Fluorescent yellow-green is used as the background color for pedestrian, bicycle, and school warning signs. Use extra caution when driving around these signs.

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.

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.

Construction, maintenance, and emergency operations signs are generally orange with black symbols.

Double solid yellow lines are used to mark roadways where passing is prohibited from both directions. You may cross these lines only to make a left turn into or from an alley, private road, or driveway.

This sign means that you are approaching an upcoming intersection. Watch carefully for cross traffic.

Factors that can affect braking distance include how fast your vehicle is traveling, the condition of your brakes and tires, and the condition of the pavement.

When you hear the siren of an emergency vehicle, you must pull over to the curb or side of the road and stop.

This sign indicates that the overpass ahead has a low clearance. You should not proceed if your vehicle is taller than the height shown on the sign (in this case, 13 feet 6 inches).

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 prohibits U-turns. Do not make a U-turn where this sign is posted.

At dusk or on overcast days, you must turn on your headlights. Dim your lights to their low beam setting when within 1,000 feet of an approaching vehicle and when within 500 feet of a vehicle that you are following. When driving in poor weather, always use your low beams.

You should use low beam headlights when driving in fog, rain, or snow.

Once leaves become wet, they can create slippery and dangerous driving conditions. The end of daylight saving time means reduced visibility on the roads, which can create unsafe driving conditions. Slow down on slick roads and increase your following distance when rain or mist begins to fall. Just a small amount of water can mix with oil and grease on the roadway to create slippery conditions.

When stopped at an intersection, you should first look to your left, as vehicles coming from the left are closer to you than vehicles coming from the right. Look to your right, then look to your left again, in case there are any vehicles coming from that direction that you did not see at first glance.

The Highway Transportation System consists of three major components: people, vehicles, and roads. It is a complex system with many diverse elements.

Backing requires extra caution because it is difficult for drivers to see behind their vehicles. Before entering a vehicle to back up, walk to the back of the vehicle to check for children and small objects.

Never pass on the shoulder of a roadway, whether the shoulder is paved or not. Other drivers will never expect you to be there and may pull off the road and into your vehicle.

The more distance between your vehicle and others, the more time you'll have to react if another driver makes a mistake. Maintain a minimum following distance of three seconds when driving under normal weather and traffic conditions. Increase your following distance when anything makes driving conditions less than perfect.

This sign indicates that workers may be on or very close to the roadway ahead, so you should take special care when traveling through the area.

One situation where it is appropriate to use your horn is if you lose control of your vehicle. In this case, sound your horn to alert other drivers.

To keep your vehicle from rolling into traffic when parked facing uphill, turn your front wheels sharply away from the curb. If you are parking uphill on a street that has no curb, turn the wheels sharply toward the edge of the road.

Do not use your high beam headlights when approaching or following another vehicle at night. Switch to the low beam setting to ensure the safety of everyone on the road.

If you look into the headlights of an oncoming vehicle, the pupil of your eye will contract. After the oncoming vehicle has passed, there will be an interval of time during which the pupil must readjust to the less intense light. During this recovery period, you are virtually driving blind.

Use the entrance ramp to accelerate to the speed of freeway traffic and yield to traffic already using the freeway. Before entering traffic, use your mirrors and check your blind spots to verify that you have room to safely merge.

A large truck has large blind spots to the front, sides, and rear of the vehicle. Avoid lingering in these areas. Because of their larger size and weight, trucks require more room to maneuver and stop than passenger vehicles.

Adjust your inside rearview mirror so you can see the entire rear window from the driver's seat. You should have to move only your eyes, not your head, when using this mirror.

Drivers must always yield to pedestrians in the street, even if they are crossing against a red light or are otherwise being careless.

Do not rely on traffic signals or signs to guarantee that right-of-way laws will be followed. Some drivers may not see or respond correctly to traffic signals. Use your best judgment when crossing an intersection.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming traffic signal. They should be prepared to respond to a yellow light, red light, and/or cross traffic.

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.

You should never drive around lowered crossing gates. Always look both ways before turning across train tracks and always obey signs and traffic signals. Trains share the road with motor vehicles and bicyclists.
