Montana Driver License DMV Test Prep

That is a deer crossing sign.

You should expect to see a school crosswalk in your current location, so proceed with caution and be prepared to stop for people crossing.

Under the “Implied Consent” law, when you drive, you have consented to the testing of alcohol or drugs in your system with your breath, saliva, blood or urine, depending upon the specific circumstances. Implied consent means that you consent to those tests if you want to drive and a law enforcement officer suspects that you are under the influence.

If you hear the siren of an emergency vehicle, but you cannot see it yet, and you do not know where it is coming from, you should pull over to the curb until you find out if it is on the same road as you.

The quickest way to find out if you should drive after taking an over the counter cold medicine would be to simply read the label, which will state if the medication causes drowsiness and may also state whether it is safe to drive while taking the medication. Calling a doctor or physician is not usually necessary.

You can be convicted of driving while under the influence of alcohol and/or any type of drug, including marijuana and over the counter drugs like cold medicine that causes drowsiness. Over the counter medications could also cause adverse reactions when mixed with alcohol.

If a truck traveling in front of you swings out towards the left before making a right turn you should slow down and stop if necessary until the truck completes its turn. Large vehicles have a bigger turning radius, which requires a right turning large vehicle to swing towards the left.

Carbon monoxide poisoning in a vehicle is caused by leaking carbon monoxide gas from a car engine and can be deadly. Carbon monoxide has no taste or smell and it is not visible to the human eye. Carbon monoxide can leak when the exhaust system is not working properly or while you are sitting in heavy traffic and breathing in the fumes of other vehicles. It can be avoided by regularly servicing the exhaust system, listening for unusual sounds underneath the car, never running the engine in a closed garage, not using the heat or air conditioner in a parked car with the windows closed and closing the fresh-air vents, while sitting in congested traffic.

Defensive driving means frequently looking around for possible hazards, which helps you anticipate any required responsive action.

When driving in fog, you should use your low beam lights, which are the regular headlights. Not all vehicles are equipped with fog lights, but if your vehicle is equipped with fog lights, then also use the front fog lights, in addition to the low beams. You should NEVER drive using only the parking or fog lights. When driving in fog, always slow down. If your cruise control is on, then turn it off, so you ensure that you are not driving too fast for the existing weather conditions and have more control over the vehicle. Also, drive with a sufficient amount of stopping space ahead of you, so you can stop within the area ahead that you can see.

Do not use high-beam headlights. High beams will not shine through the fog. Rather, high beams will reflect the light back into your eyes and make it more difficult for both you and other drivers to see.

You most likely have the right-of-way if you are already in a traffic circle. Vehicles entering the circle have to yield to vehicles already in the circle.

You should always use your turning signal whenever you change lanes. Turn the signal off once you have completed the lane change. Also, leave sufficient distance between you and the other nearby vehicles when changing lanes. By failing to signal, it can cause another driver to act aggressively or engage in “road rage”.

This sign does not allow parking in a bike lane.

Warning signs are usually diamond shaped with black writing on a yellow background and warn of a potential hazard, obstacle or condition that requires a driver’s special attention.

Temporary warning signs, which are usually construction signs, are black on an orange background.

An interstate number sign is in the shape of a shield.

A sign that is rectangular-shaped is a speed limit sign.

If you see a school bus with its red lights flashing, you must stop under any and all circumstances.

A five-ounce glass of wine contains about the same amount of alcohol as a twelve-ounce beer. One ounce of beer contains less alcohol than one ounce of spirits, but the standard serving size of beer is twelve ounces. One and a half ounces of 86-proof liquor, which is what most spirits (hard liquor) contain, has around the same amount of alcohol as a twelve ounce beer or five ounces of wine.

When parallel parking on a level street, make sure that you straighten your front wheels and leave sufficient space between the front of and back of your vehicle and the other vehicles.

If a traffic light is not working, including if no lights appear, then proceed through the intersection with caution as if all directions are controlled by a stop sign.

At an intersection that has no traffic control device, a driver approaching an intersection must yield the right-of-way to traffic already lawfully within the intersection.

A traffic light with both a green arrow and a red light means that you may drive only in the direction of the green arrow.

The first choice tells you that the road will wind to the right.  The second choice means winding road to the left. The third choice means the road curves right with an entry road. The last choice means slippery when wet.
