New Hampshire CAR DMV Practice Test 18

One strategy to avoid driving while impaired or intoxicated is to arrange for a ride home with a friend who does not drink. Drinking coffee or taking a cold shower cannot reduce your blood alcohol content or reduce the effects of alcohol. On average, it takes about an hour for the body to eliminate the alcohol from a single drink.

If you arrive to an open intersection at the same time as a vehicle to your right, you should yield the right-of-way to that vehicle. You may then proceed when it is safe to do so.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign indicates that drivers are approaching a steep hill and should prepare to adjust their speeds to continue to drive safely.

A green light tells you that you can go through the intersection. However, you must first yield the right-of-way to traffic and pedestrians who are still in the intersection.

The most important thing to remember about driving in curves is that your vehicle’s inertia may make it difficult to turn. To maintain control, it is essential that you slow down before entering the curve.

Warning signs that indicate approaching hazards are usually yellow with black lettering or symbols. Warning signs in work zones are orange with black lettering or symbols.

Before turning or changing lanes, turn your head and glance over your shoulder in the direction of your move to see if your blind spot is clear. Never rely on your mirrors alone.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential traffic merging from the right. Drivers should prepare to allow the traffic to merge safely.

When the road is wet or slippery, when you cannot see well, or when anything else makes conditions less than perfect, drive below the posted speed limit. Even if you are driving within the posted speed limit, you can still be ticketed for driving too fast for conditions.

A flashing yellow light means that you should proceed through the intersection slowly and with caution. Scan your eyes across traffic in both directions.

"Highway hypnosis” happens when you stare straight ahead at the roadway for long periods of time and stop actively scanning ahead, behind, and around your vehicle. This can lead you to zone out, making you very likely to crash into traffic slowing or stopping ahead of you.

The distance that a vehicle needs to stop depends on the motorist's reaction time, weather and visibility conditions, the vehicle's weight, the conditions of the vehicle's brakes, the condition and type of the vehicle's tires, roadway conditions, and speed.

Safety belts are very simple devices that can prevent injury or death in the case of a crash. Anyone under 18 years of age is required by law to be properly restrained by a safety belt when in a moving vehicle, but it is highly recommended that everyone in a vehicle uses a safety belt, regardless of age.

This sign indicates that there is a railroad crossing on the road ahead. You should always slow down when approaching a railroad crossing. Trains cannot yield to cars, so you must let them pass before crossing the tracks.

Choosing to eat, drink, or smoke while driving is dangerous because these actions require a driver to remove their hands from the wheel and their eyes from the road. Drivers who engage in distracting activities while driving have trouble staying in their lanes and controlling their vehicles.

Do not become distracted by looking at passengers, attempting to find something in your vehicle, looking at reading material, sightseeing, or daydreaming while driving. If a driver near you seems distracted, allow them extra space because the risk of an accident is increased by their inattentiveness.

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.

Alcohol reduces your reaction time, reduces your ability to see clearly, changes your judgment of speed and distances, reduces your ability to recover from the glare of headlights, and often reduces your inhibitions and makes you more likely to take risks.

To avoid the dangers of road rage, you should never take it personally if another driver cuts you off in traffic. Just let it go and continue driving safely.

Your horn should be used as a warning in situations where you think another driver or a pedestrian does not see you. For example, if a child begins to run into the street in front of your vehicle, you should sound your horn.

If you miss your exit, you should take the next exit. Do not stop or back up on the highway, swerve across multiple lanes to try to make the exit at the last second, or cross over the median to turn around. All of these maneuvers are illegal and extremely dangerous.

When driving near heavy trucks, other drivers and highway users must make allowances for the increased stopping distance required by the large vehicles. Drivers of smaller vehicles should remain in locations where they can be seen by the driver of the large vehicle and where their view of traffic is not blocked by the vehicle.

This is a speed limit sign. It indicates the maximum legal speed that you may drive on the road where it is posted. At times of rain, snow, ice, or other less-than-ideal conditions, you may have to drive more slowly than the posted limit.

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.

This sign indicates that U-turns are prohibited.

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 a vehicle comes toward you with its high beams on, look away from the headlights and toward the right side of the road until the car has passed. This will keep you from being blinded.

A steady yellow light on a traffic signal indicates that a steady red light will soon appear.

Distracted driving is extremely risky behavior that puts not only you and your passengers in danger, but also endangers pedestrians, bicyclists, and other motorists sharing the road. Focused attention on driving helps to prevent crashes.

Traffic flow is controlled by pavement markings, traffic islands, signals, and signs. These devices inform drivers of conditions on the roadway and help guide drivers safely to their destinations. You must always obey traffic signs, signals, and pavement markings.

Be prepared to reduce your speed and use caution when directed to do so by a sign, crossing guard, or law enforcement officer. Always drive with extra caution in a school zone.

This sign warns of an upcoming winding road with three or more curves.

Yellow centerlines are used to separate traffic moving in opposite directions. Broken lines may be crossed to pass slower-moving traffic when it is safe to do so.

To check your blind spot, glance over your shoulder in the direction that you want to move.

If the weather changes suddenly, you will need to adjust your driving to adapt. Always slow down when driving in rainy or foggy conditions. Be especially aware of vehicles behind you that may be going too fast for conditions.

To slow down on a slippery road, you should first take your foot off the gas pedal. If you need to slow down even more, gently apply a slow, steady pressure to your brake pedal.

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

This sign warns that a traffic signal is ahead.

You must always bring your vehicle to a complete stop and yield to approaching traffic before proceeding past a stop sign. Don't feel pressured by surrounding traffic to avoid making a complete stop.

When driving to an unfamiliar area, plan your trip in advance. Don’t start with only a hazy idea of where you are going. If your destination is in an unfamiliar area, check the location on a map before you start to drive.
