Montana CAR DMV Practice Test 10

Warning signs advise drivers of potentially hazardous conditions. For your own safety, obey warning signs. Disregarding the information provided by a warning sign may result in an accident due to your negligence.

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.

You must yield the right-of-way to all emergency vehicles using a siren, air horn, and/or flashing red, blue, or white lights. Where possible, you must pull over to the right edge of the road. If you are in an intersection, drive through the intersection before you pull over.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign warns drivers to be extra careful when the pavement is wet because the road may become slippery, making vehicles more difficult to control.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

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.

This sign warns of the presence of a crossroad ahead.

Fatigue and being under the influence of alcohol have similar effects on your ability to drive safely. For example, being awake for 18 hours impairs your driving about as much as a blood alcohol level of 0.05 percent. Being awake for 24 hours in a row has the same effect on your driving as a blood alcohol level of 0.10 percent.

If you are involved in an accident, you must stop at or near the scene. Move your vehicle out of the way of traffic, if possible. Do not stand or walk in traffic lanes as you could be struck by another vehicle. Turn off the ignitions of wrecked vehicles.

When entering a freeway, use the on-ramp to accelerate to the speed of freeway traffic so you can blend in smoothly and safely. Entering traffic must yield to traffic already on the freeway.

The only way to be sure you will have enough time to react to mistakes made by other drivers is to leave plenty of space between you and the vehicles around you.

Large vehicles can cause wind gusts with a force great enough to cause direction changes in smaller vehicles. Drivers of small vehicles should be prepared to take proper corrective steering action when approaching or passing large vehicles that are moving at or near maximum speeds.

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.

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.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers should keep right to avoid an upcoming potential driving hazard.

At an intersection of two similar roads without a traffic control device, a driver must yield to a vehicle approaching from the right.

Alcohol goes from your stomach into your blood, then to all parts of your body. It reaches your brain 20 to 40 minutes after consumption. Alcohol affects the areas of your brain that control judgment and skill.

Factors that can affect braking distance include how fast your vehicle is traveling, the condition of your brakes and tires, and the condition of the pavement.

To complete a turn safely, you should activate your turn signal three to four seconds before your turn.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. Wherever this regulation sign is posted, U-turns are not permitted.

Don’t make a last-minute turn into an exit. If you pass your exit, you must go to the next one.

You must always signal before turning or changing lanes. You should keep your wheels straight while waiting to make a left turn. If another vehicle hits you from behind, this ensures that you will not be pushed into oncoming traffic.

If a steady yellow light appears when you are already within an intersection, you should continue through the intersection carefully.

Alcohol negatively affects many skills needed for safe driving, including your reaction time and ability to see clearly. It can also harm your judgment of speed and distance, lower your inhibitions, and make you more prone to taking chances.

This sign indicates that right turns are prohibited. Do not make a right turn at an intersection where this sign is posted.

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

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

To avoid the need for last-minute braking or turning, you should look down the road at least 10 seconds ahead of your vehicle. By looking well ahead and being ready to stop or change lanes if needed, you can drive more safely and help keep traffic moving at a steady pace.

An arrow painted on the pavement within a traffic lane indicates that drivers in the lane must make the movement indicated by the arrow. Drivers should follow directions given by any traffic signs or signals before proceeding in the direction indicated by the arrow.

Before changing lanes, you should look in your rearview and side mirrors to make sure no one is trying to pass you. You should also look over your shoulder to make sure that no one is in your blind spot.

If your vehicle breaks down on the highway, you should signal before carefully exiting the roadway and turning on your hazard flashers. Get as far off the road as possible and park in a location where other drivers can easily see you. Lift your hood to let other drivers know your vehicle is disabled.

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.

You cannot pass safely when driving on a two-way, two-lane street unless you can clearly see the road ahead, you can return to your lane before meeting oncoming traffic, and your vehicle is capable of the speed necessary to pass. Do not pass where it is illegal and unsafe to do so.
