Montana CAR DMV Practice Test 15

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.

This sign is used with a traffic signal to tell drivers that left-turning traffic does not have the right-of-way and must instead wait for oncoming traffic to clear.

Do not become distracted by looking at passengers, attempting to find something in your vehicle, looking at reading material, sightseeing, or daydreaming while driving. If a driver near you seems distracted, allow them extra space because the risk of an accident is increased by their inattentiveness.

As alcohol builds up in your system, it will slow your reactions, make you feel more confident, and cause you to make more errors.

If another vehicle is approaching you head-on in your lane, you should first honk your horn to attract attention. If the other driver does not move over, try to escape to the right. If you swerve left and the other driver corrects at the last instant, you will still crash. If a collision is unavoidable, brake firmly and steadily. Every mile per hour you slow down will reduce the impact.

This sign means that you are approaching an upcoming intersection. Watch carefully for cross traffic.

When changing lanes or turning, signal your intentions well in advance. The law requires that you signal for at least 100 feet before you move your vehicle to the right or left. Before pulling away from a curb, always signal to inform passing drivers of your intentions.

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.

When making a left turn where there is approaching traffic, you must wait for the approaching traffic to go through before you turn. You may enter the intersection to prepare for your left turn if the light is green and no other vehicle ahead of you plans to make a left turn.

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

Circular traffic signs indicate upcoming railroad crossings. This sign tells drivers that they are approaching a railroad crossing and should be looking for signs of an oncoming train.

This sign indicates that a divided highway begins ahead. The road will split into two one-way roadways separated by a median or divider. You must keep to the right.

When there is a solid yellow line and a broken yellow line in the center of the road and the broken line is next to your lane, you may cross the lines to pass if there is no oncoming traffic.

Upon meeting any school bus stopped with its red lights flashing, the driver of a vehicle coming from either direction must stop at least 30 feet from the bus. A driver cannot proceed until the flashing red lights have been extinguished.

When preparing to drive, you should first adjust your seat to ensure that you are in a comfortable position and can see the road clearly. Adjust your mirrors and steering wheel to be effective when your seat is fully adjusted.

These signs indicate that the road curves to the right ahead and that drivers should slow down to the safe speed indicated (in this case, 35 mph).

Signs that are brown indicate areas of cultural and historical significance or of public recreation. They can be a helpful resource when traveling in unfamiliar locations.

Before passing, you should signal early enough for other drivers to know your plans in advance.

You must do everything you can to prevent striking a pedestrian or another vehicle, regardless of the circumstances. It is the driver’s basic responsibility to be alert to pedestrians and to yield the right-of-way to all pedestrians, even if the pedestrian is crossing the street where they should not be.

Even the most experienced drivers can be distracted while driving. A defensive driver looks out for the actions of other drivers and anticipates potential problems.

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.

At four-way stops, traffic from all four directions must stop. The first vehicle to reach the intersection should move forward first. If two vehicles reach the intersection at the same time, the driver on the left yields to the driver on the right.

When stopped at an intersection, you should first look to your left, as vehicles coming from the left are closer to you than vehicles coming from the right. Look to your right, then look to your left again, in case there are any vehicles coming from that direction that you did not see at first glance.

Your vehicle's brake lights indicate to other drivers that you are slowing down or stopping. Your brake lights should always be in working order when you are driving on any roadway.

When exiting a highway, you should get into the exit lane well in advance. Do not begin to slow down until after you have moved into the exit lane.

Yellow lines tell you that the traffic on the other side of the lines is moving in the opposite direction. You should never cross two solid yellow lines to pass from either direction.

This sign warns that pavement is slippery when wet. In wet conditions, you should reduce your speed, avoid braking or changing direction suddenly, and increase the distance between your vehicle and the one ahead.

When applying for a learner license, a teenage driver under the age of 18 must have a consent form signed by a parent/guardian. Signing this form obligates the parent/guardian to accept financial responsibility for any damage that is a result of the minor operating a motor vehicle.

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.

You should never drive around lowered crossing gates. Always look both ways before turning across train tracks and always obey signs and traffic signals. Trains share the road with motor vehicles and bicyclists.

If there is no stop line or crosswalk, you should stop at the point nearest to the intersecting roadway where you can get a view of approaching traffic. You should not enter the intersecting roadway to gain a better view.

Driving too fast for conditions is a major cause of motor vehicle crashes. Being inattentive to surroundings can cause a driver to collide with other vehicles. Most rear-end collisions are caused by drivers following other vehicles too closely.

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.
