Wyoming CAR DMV Practice Test 12

Before you return to your driving lane, be sure you are not dangerously close to the vehicle you have just passed. One way to do this is to look for the vehicle in your inside rearview mirror. When you can see both headlights in your rearview mirror, you may have enough room to return to your driving lane.

To drive quickly, pass, or turn left, use the left lane. Use the right lane when driving more slowly than surrounding traffic, entering the road, or turning right.

If you want to enter the freeway but do not see a space for your vehicle in traffic, slow down on the ramp to wait for a gap. Do not drive to the end of the ramp and wait for a gap or you will not have enough room to accelerate to the speed of traffic before entering the roadway.

You should be extra careful when turning and stopping during the first half hour of rain. At this point, the oil from cars has not yet washed off the pavement and could be forming a slippery mixture with the rain.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign tells drivers to slow down and prepare for an abrupt change in direction at an extreme angle.

Allow for extra space when driving behind a motorcycle. Motorcycles can stop more quickly than other vehicles can and you must have adequate room to stop if the motorcyclist brakes or falls off. Also, remember that motorcycles are difficult to see at night because they only have one tail light.

On the freeway, be ready for changes in traffic conditions. Watch for signals from other drivers. Expect merging vehicles at on-ramps and interchanges and be prepared for rapid changes in road conditions and traffic flow.

When passing a motorcycle, allow a full lane to the motorcycle. Never crowd into the same lane as the motorcycle. Returning to the original lane too soon can force a rider to swerve to the right and into traffic or off the road.

When driving in winter weather, maintain a following distance of at least four seconds. Watch the car in front of you pass a landmark, then start counting. If your car reaches the same landmark before you count to four, you are following too closely.

A red arrow means "stop." You must remain stopped until a green light or green arrow appears. Do not turn against a red arrow.

A broken yellow centerline next to your side of the road indicates that traffic may cross the centerline to pass from your side of the road.

Any amount of alcohol acts as a depressant, slowing the function of the nervous system. It will reduce a person's alertness and ability to concentrate, increase their reaction time, and drastically reduce their coordination.

When driving too quickly in wet conditions, your tires may lose all contact with the road surface. Loss of traction will cause the vehicle to ride on top of the water, which is called "hydroplaning." The best way to prevent this from happening is to drive more slowly in rainy or wet conditions than you would when driving during ideal weather conditions.

You may proceed in the direction that a green arrow signal is pointing if you are in the proper lane, regardless of any other signals that are displayed. Before turning, you must yield the right-of-way to pedestrians and vehicles already within the intersection.

If your vehicle breaks down on a highway, make sure other drivers can see it. Get your vehicle off the road and away from traffic if at all possible and turn on your emergency flashers to show that you are having trouble.

While waiting to turn left, keep your wheels pointed straight ahead until it is safe to start your turn. If a vehicle hits you from behind, this will prevent you from veering into oncoming traffic. When parked facing either uphill or downhill, turn the wheels so the vehicle will not roll into traffic if the brakes fail.

If your vehicle becomes disabled, you must (if possible) park with all four wheels off of the main-traveled portion of the road.

Any time you come to a place where people may cross or enter your path, or where one line of traffic meets another, you should look to the left and right sides of your vehicle to make sure no one is coming.

When a school bus is flashing its red lights and has its stop arm extended, motorists must come to a full stop until the lights are turned off, the stop arm is withdrawn, and the bus begins moving again.

You should drive more slowly at night than during the day because it is not possible to see as far ahead at night. You should make sure that you can stop within the area illuminated by your headlights.

If your vehicle has a two-part seat belt system, be sure to wear both the lap belt and the shoulder belt. Wearing either part alone greatly reduces your protection. If you have an automatic shoulder belt, be sure to buckle your lap belt as well.

A wet, slippery road does not allow your tires the traction they need, so it is necessary to drive more slowly on a wet road than you would on a dry road. To reduce the risk of skidding, you should avoid fast turns or stops.

The speed at which you should drive your vehicle depends on road conditions, the weather, and the legal speed limit. You may never drive above the legal speed limit. Decrease your speed when anything makes conditions less than ideal.

A triangular red and white sign indicates that you must yield the right-of-way.

If you notice that the road ahead is covered by heavy smoke, reduce your speed immediately, drive as far as possible to the right, and stop off the roadway. Only then should you determine if it is safe for you to continue. Remember that certain kinds of smoke can irritate your eyes and lungs or even kill you.

When entering any roadway, you must be aware of traffic conditions. Use your side mirror and look over your shoulder to help you see and anticipate traffic when entering a freeway.

You are driving defensively when you are looking down the road for potential hazards. Constantly staring at the road directly in front of your vehicle is dangerous. As you scan ahead, be alert to vehicles around you.

Drivers must respect and cooperate with all other road users and conform to specific rules in order to maintain order and to avoid crashes. When encountering an aggressive driver, it is safest to just get out of their way. Always avoid competing with other drivers.

Warning signs are usually yellow with black markings. This sign warns that your current road ends at an intersection straight ahead. Slow down and prepare to yield or stop before turning right or left.

Before changing lanes, it is very important to check behind you. You should look over your shoulder to ensure that you are not getting in the way of vehicles in the lane you want to enter. Before changing lanes, you should also ensure that no drivers are attempting to drive into the same spot from a different lane.

Regulatory signs inform drivers of specific laws that must be obeyed. Displayed laws may be about traffic direction, lane use, turning, speed, parking, or special situations. Regulatory signs are commonly white squares or rectangles with black, red, or green letters or symbols.

At an intersection controlled by a steady yellow light, you should bring your vehicle to a safe stop. If you are already within the intersection when the light changes from green to yellow, continue through the intersection at a safe speed.

A round yellow sign indicates that there is a railroad crossing ahead.

When changing lanes, look over your shoulder in the direction you plan to move. Check for obstructions near the rear corners of your vehicle. These areas are called “blind spots” because you cannot see them by using your mirrors.

Always be aware of what is happening around your vehicle. Constantly observing your surroundings to the front, sides, and rear of your vehicle will help you see problems that may require you to change speed or roadway position.
