New Hampshire CAR DMV Practice Test 23

This sign indicates that you must keep to the right of the upcoming divider.

An octagonal shape is used only for stop signs. All eight-sided signs tell drivers to come to a complete stop before proceeding.

Reduce your speed when roads are snow-covered or icy. Doing this and increasing your following distance are the most important techniques for avoiding crashes under snowy or icy conditions.

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

In a school zone, the speed limit is 10 miles per hour below the usual posted speed limit. This restriction is in effect from 45 minutes before the school is in session until the school day begins, as well as from the end of the school day until 45 minutes after the school closes. Drive with extra caution when driving through a school zone at any time.

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.

A sign with a red circle and slash over a symbol indicates that the action represented by the symbol (in this example, a right turn) is not allowed.

Be very cautious any time you encounter an animal on the roadway. Pass the animal slowly to avoid startling or frightening it.

This sign warns that especially slippery conditions exist when the road is wet.

Pennant-shaped signs usually indicate no passing zones. Text will also be on the sign to confirm that it is a no passing zone.

Your ability to handle dangerous traffic situations depends largely on searching for and identifying problems before meeting them. Looking far ahead of your vehicle does not mean you should simply stare at the center of the road. You need to continually scan the entire road, including the sides of the road.

When you see any signs indicating a nearby railroad crossing, you should slow down, look for a train, and be ready to stop. If the red warning lights are flashing or the gate is down, you must stop 15 to 50 feet before the railroad tracks. Do not try to go around the gate.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign tells drivers that they are approaching a school zone and that they should slow down and watch for children.

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.

Your physical condition has an important bearing on your ability to drive safely. Drivers should be aware of their physical limitations and only drive if it is safe to do so.

Because a large vehicle, such as a truck or bus, has large blind spots to its sides and rear, avoid driving alongside such a vehicle and do not tailgate one.

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

Blind spots are areas that a driver cannot see without moving their head. They can be located to the sides of and behind a vehicle.

Because hydroplaning is caused by driving too quickly in wet conditions, the risk of it happening can be reduced by driving more slowly.

When stopped for a traffic violation or at an equipment check, the driver is responsible for producing 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.

If you are stopped by the police, keep your hands on the wheel and ask any passengers to keep their hands in view as well. You should remain in the vehicle unless the police officer asks you to get out. Wait until the officer asks you to retrieve your driver license, registration, and insurance cards.

It is important to stay alert on highways and be ready to react to unexpected hazards. To avoid "highway hypnosis," you should avoid looking at any one thing for more than a few seconds.

When stopped behind another vehicle, stay back at a distance that allows you to see the ground under the vehicle’s rear wheels. This will allow you to safely move around the vehicle if needed. A space cushion will also help if you are parked on a hill and the car in front of you begins to roll backward after the driver releases the brake pedal.

High speeds greatly increase stopping distances and severity of crashes. The faster you drive, the greater the impact or striking power of your vehicle, should you be involved in a collision.

The average person’s body will process about one alcoholic drink in one hour. However, many factors play a part in determining how impaired a person will become when consuming alcohol, including the amount of alcohol consumed, how fast it is consumed, and a person’s body weight, food intake, and general health.

Crashes often happen because one driver does something that other road users are not expecting. You should communicate with other motorists, bicyclists, and pedestrians by doing things like signaling when slowing down, stopping, or changing direction. Use your emergency signals or horn when appropriate.

Entrance ramps for highways often have acceleration lanes. When merging with traffic from an acceleration lane, you should put your signal on, look for an opening in traffic, accelerate up to the speed of traffic, and merge into an opening in traffic.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

You may not be able to drive well if you are worried, excited, crying, angry, or depressed. Emotions can distract you from your driving because your mind is focused on something else. Take time to calm down and get focused before driving.

Stopping suddenly can make it difficult for drivers behind you to avoid a rear-end collision. When stopping, release the accelerator to allow your vehicle to slow. Press the brake pedal by applying steady pressure, activating your brake lights and causing the vehicle to stop smoothly.

A solid line along the side of the road indicates where its edge is, marking the boundary between the travel lane and the shoulder. If the edge line angles toward the center of the road, this means that the road is narrower ahead.

Unless a posted sign indicates otherwise, a traffic signal displaying a red arrow means that drivers must come to a full stop and remain stopped until a green light or green arrow appears.

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).

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.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign indicates that the divided highway is about to end.

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.

If you approach an emergency vehicle, tow truck, or roadside assistance vehicle that is stopped with its lights flashing, you must change lanes to allow the vehicle extra space. If there is only one lane moving in your direction, or if changing lanes would be unsafe, you must slow down to a speed below the posted speed limit and give the stationary vehicle as much room as possible. Always slow down and be prepared to stop when you approach an emergency scene.

To prevent drowsiness on long trips, you should schedule regular stops. Give yourself time to rest and stretch, even if you are not feeling tired.

When approaching a railroad crossing, you must stop your vehicle no closer than 15 feet from the nearest rail if an installed electric or mechanical signal is giving warning of an approaching train. Be aware of other warning signs that may indicate an oncoming train, including seeing a lowered crossing gate or hearing an oncoming train.

If you are turning left from a two-way street onto a one-way street, you should complete the turn into the lane closest to the lane you have just left.
