New Jersey CAR DMV Practice Test 9

When you are approached by an emergency vehicle that is using its lights, sirens, and/or other warning devices, you must immediately drive to the right side of the road and stop.

Consuming alcohol and other drugs together can increase the impairing effects of both. For example, having one drink while you are also using a cold remedy could affect you as much as several drinks would when being consumed separately from any medications.

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.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming intersection.

Before changing lanes, you should always verify that there are no other vehicles in the lane you want to enter by checking your mirrors and looking over your shoulder in the direction you plan to move. You should signal every time you change lanes.

Double solid yellow lines in the center of the road mean that passing is not allowed from either direction. You may not cross the lines unless you are making a left turn or passing pedestrians, bicyclists, and riders of scooters or skateboards when the opposite lane is clear and you can pass safely.

The steering wheel can be thought of as the face of a clock. For normal driving, a motorist should grip the steering wheel by the outside rim at the 9 o'clock and 3 o’clock positions, keeping their thumbs along the face of the wheel.

You should pass a bicyclist the same way you would pass any other vehicle, but not so fast or close to them that you throw debris in their face or blow them around with the draft of air from your vehicle. Allow at least 3 feet of space between your side mirror and the bicyclist, or at least 5 feet on higher speed roads or when there is a group of bicyclists. Honking unnecessarily may startle riders and make them more likely to crash.

If you must drive in foggy conditions, you should use your low beam headlights, as well as your fog lights, if your vehicle has them. High beams direct their light upwards, where it can bounce off the fog and into your eyes, reducing visibility even more.

This sign warns that a traffic signal is ahead.

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 you leave your vehicle unattended, you must stop the engine, lock the ignition, remove the key from the ignition, and set the parking brake.

Warning signs are usually diamond-shaped and yellow with black lettering or symbols. They warn drivers about special situations or potential hazards ahead.

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.

This sign indicates that there is a traffic signal ahead.

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

You must always stop before crossing railroad tracks if flashing red lights are activated, a crossing gate is lowered, a stop sign is posted, a flagger signals you to stop, or a train is visible or so close to the crossing that it would be hazardous to continue driving. If you are unsure if a train is too close for you to safely cross the tracks, stop. Never race a train.

Curve and turn warning signs often have attached advisory speed signs that show a recommended driving speed for drivers in the curves and turns. Although a driver may feel comfortable driving at a higher speed in fair weather, they should never do so under rainy, snowy, or icy conditions.

Unless a posted sign prohibits it, you may turn right or left at a steady green light. When turning, you must yield to other vehicles and pedestrians within the intersection.

This advisory speed sign indicates the maximum safe speed for a highway exit (in this example, 30 mph).

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.

You should never pass if there is an oncoming vehicle in the passing lane, if your view is blocked by a curve or hill, at an intersection, before or on a railroad crossing or bridge, or in any other no passing zone. Unless you are on the opposite side of a multilane roadway with a median or shared center turn lane, you may not pass a stopped school bus that has its flashing red lights activated.

Alcohol dulls the parts of your brain that control inhibition, judgment, and self-control. As a result, you may feel stimulated, lively, and a bit giddy or foolish after consuming alcohol. Alcohol also impairs your reaction time, coordination, and balance. Your vision and ability to judge distance suffers after alcohol consumption, making it difficult to react to your surroundings.

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

This sign indicates a low ground railroad crossing. Where this sign is present, railroad tracks cross the road at a steep slope and the bottom of low vehicles may drag or get caught on the tracks.

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.

A steady yellow arrow indicates that a red arrow is about to appear. Stop unless you are already within the intersection.

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

This sign indicates that U-turns are prohibited.

Tractor-trailers take longer distances to stop than smaller cars traveling at the same speed. A fully loaded tractor-trailer may take almost 400 feet to come to a complete stop when driving at 55 mph.

After stopping for a school bus that has its stop arm extended and its lights flashing, watch for children walking along the side of the road. You should always drive with caution when driving near children.

A driver who is under the age of 21 and operating on a Graduated Driver License (GDL) must practice supervised driving for a minimum of six months before taking the official road test. A driver age 21 or older who is operating on a GDL must practice supervised driving for a minimum of three months.

This sign means that it is not safe for drivers to enter the indicated road or driveway from their current direction. If you come across one of these signs, you should immediately turn around and drive a different way.

When approaching an intersection with a steady green traffic light, yield to pedestrians in the crosswalk and vehicles still in the intersection. You may continue driving, but should approach the intersection at a speed that will allow you to slow down and stop if the light changes before you get there.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers that they are approaching an area with low clearance.
