New Jersey CAR DMV Practice Test 17

A driver operating with a GDL may not use any electronic devices, such as a cell phone, while behind the wheel. All New Jersey drivers must wear a seat belt while driving.

Using a cell phone (including a hands-free phone) or any kind of audio device (including a radio or CD player) can be a dangerous distraction and contributes to the risk of a crash.

A yield sign means that you must slow down and yield the right-of-way to traffic in the intersection or roadway you are entering.

This sign indicates that the road ahead will turn sharply to the right and then to the left.

Drivers under age 21 (the legal age to purchase or consume alcoholic beverages in New Jersey) will be penalized if they are found with a blood alcohol concentration (BAC) of 0.01 percent or more.

Drugs (including illegal, prescription, and over-the-counter medications) can affect your brain function and impair your ability to drive safely. Combining alcohol with other drugs will increase the risk of a crash.

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

A green arrow displayed on a traffic signal tells drivers that they may turn in the direction of the arrow. You must be in the proper lane for such a turn. Yield the right-of-way to vehicles and pedestrians already in the intersection.

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.

In snowy weather, keep your windshield and mirrors clear. Increase your following distance when driving in wet and cold weather because a slippery road surface will increase the distance needed for your vehicle to stop.

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.

You must yield to other drivers when entering a street from an alley, driveway, or garage. You must also yield to pedestrians who are on an intersecting sidewalk.

If a driver's left arm and hand are extended upward, they are indicating that they intend to turn right. Adjust your driving accordingly if following a driver who is using this hand signal.

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.

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

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.

You must always yield to pedestrians who are in or about to enter a crosswalk. Be alert to pedestrians when driving across intersections or turning.

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.

When the driver behind you wants to pass, you should slow down so that there is enough room in front of your vehicle for the other driver to complete their pass. This will allow them to complete the passing maneuver in less time and more easily.

Unless otherwise posted, the speed limit in residential districts is 25 mph. If a different speed limit is posted, you should follow that speed limit.

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.

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

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.

Work zone signs are orange and indicate that some type of work is being performed on or alongside the roadway. Be extremely careful when you see these signs.

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 you drive, make sure each person in your vehicle wears a seat belt. In the event of a crash, a person without a seat belt becomes a flying object and a danger to each person in the vehicle.

As speed increases, the chance of a fatality increases. If you are moving faster than 80 miles per hour, you have almost no chance of living through a crash. Driving more slowly than other traffic can also be dangerous because other motorists may become impatient and make dangerous moves to pass you.

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.

It is prohibited to park on the shoulder of a freeway, except in an emergency.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers to be cautious when driving under conditions that may cause the roadway to become wet and slippery.

Under state law, the driver and all passengers of a passenger vehicle must wear a seat belt. The failure of a driver, front seat passenger, or child under age 18 to wear a seat belt is a primary offense. The driver is responsible for all passengers under age 18. Under a secondary law, all unbuckled back seat occupants 18 years of age and older may be issued a summons if the vehicle has been stopped for a different reason.

A solid yellow line next to your lane means that passing is not permitted from your direction.

The amount of space you need to cross traffic depends on the road conditions, weather conditions, and oncoming traffic.

Drinking coffee will not reduce your blood alcohol concentration (BAC). While it may help you to stay awake, it cannot change your BAC or make you sober.

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.
