Montana CAR DMV Practice Test 9

Many kinds of drugs can impair your ability to drive. This includes illegal drugs and legal prescription or over-the-counter medications. It can be a criminal offense to drive while impaired by any drug.

Your turn signals should always be used when you make any movement to the left or right. You should use your signal when pulling into traffic from a curbside parking space, moving into a new lane, or passing another vehicle.

You are required to stop at all railroad crossings when signals warn of an approaching train. These signals may include flashing red lights, a lowered crossing gate, a flagger signaling, or a train’s audible signal of warning. Do not attempt to go around a lowered gate.

If there is an available passing lane, you may pass on the right of a vehicle or bicycle that is turning left or waiting to turn left. It is also legal to pass on the right when driving on a multilane road with two or more lanes traveling in the same direction. You may never drive off the pavement or main-traveled portion of the road to pass another vehicle.

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

On slippery roads, you should increase your following distance. It may take more time to stop your vehicle than it would under normal conditions.

You may not pass another vehicle on a hill or in a curve because you cannot see oncoming traffic and may cause a collision. Never pass another vehicle by driving onto the shoulder of a highway. Passing another vehicle by driving over a solid yellow line is prohibited.

In many collisions with motorcycles, bicycles, and pedestrians, drivers reported that they were looking but still did not see the smaller vehicle or pedestrian. These can be more difficult to spot in traffic than passenger vehicles because they are smaller, may move faster, and have less noticeable lighting. To prevent collisions with these smaller and less protected road users, drivers should always be alert to the presence of motorcycles, bikes, and pedestrians.

A flashing red light means the same thing as a stop sign. If you encounter a flashing red light, you should come to a complete stop, yield to appropriate traffic and pedestrians, and only proceed when it is safe to do so.

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

Pentagonal signs indicate that you are in a school zone. Be extra alert to children and pedestrians when driving near a school.

If there are two railroad tracks next to each other, watch for a second approaching train after one train passes. Do not begin to cross the tracks until you’re sure no train is approaching from either direction on either track.

Pedestrians should walk on the side of the road facing the traffic in the lane nearest them.

This sign (with the arrow below) indicates the location of a bicycle crossing/path. Drive with caution around this sign because bicycles likely regularly cross or ride beside traffic in the area.

This signs indicate that U-turns are prohibited in the location where it is posted.

Signs providing information about destinations are green with white letters or symbols.

A flashing yellow traffic light means drivers should slow down and proceed with caution.

You should turn your head to check your blind spots before every lane change.

You should always slow down when driving on narrow or winding roads, near intersections, near railroad crossings, on hills, in sharp or blind curves, where there are pedestrians or driving hazards, and when the roads are wet or slippery.

Upon striking an unattended vehicle, stop and try to locate the owner. If you cannot find the owner, leave a written notice containing your name, your address, and the circumstances of the accident.

You must yield to any transit vehicle that is signaling to pull back onto the main roadway after it has stopped to load or unload passengers. Change lanes, slow down, or stop to allow the bus safe re-entry into traffic.

At dusk or on overcast days, you must turn on your headlights. Dim your lights to their low beam setting when within 1,000 feet of an approaching vehicle and when within 500 feet of a vehicle that you are following. When driving in poor weather, always use your low beams.

Drivers must be aware that large vehicles often travel at a speed slower than the posted speed limit, especially when driving on an incline, and should use caution when approaching a large vehicle from the rear. When on a hill with limited visibility, it is unlawful to pass another vehicle.

On narrow roads, you must allow vehicles traveling in the opposite direction at least one-half of the main-traveled portion of the road. Both vehicles must have adequate space in order for the drivers to safely pass one another.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers turning left at a green light must yield to oncoming traffic and may complete the turn when it is safe to do so.

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.

The faster you drive on a wet roadway, the less effective your tires will be at wiping the water from the road. If your speed becomes excessive enough, your tires will lose their grip on the road entirely and you will begin to hydroplane (that is, to slide down the road on a film of water).

To avoid becoming fatigued while taking a long trip, stop every two hours for a short break. If you become drowsy, pull off the road and park in a safe place to take a nap, or find a room to stay for the night.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

Solid white lines are used to separate lanes traveling in the same direction (as well as to mark the right edge of the road). Broken white lines separate lanes traveling in the same direction and may be crossed to pass. Yellow lines separate lanes of traffic moving in opposite directions.

When the road is wet, most tires have good traction up to about 35 mph. As you travel faster, your tires may leave the surface of the road and start to glide on a film of water. This is called "hydroplaning."

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

Regulatory signs display laws that drivers must always obey. Right turns are not permitted where this sign is present.
