Arizona: DMV Practice test

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.

A number of drugs can impair your ability to drive, including depressant medications like tranquilizers and sedatives; over-the-counter cough syrups, cold tablets, and allergy medications (which may contain impairing substances like alcohol, codeine, or antihistamines); and illegal drugs.

Alcohol, in any concentration, is a depressant. It slows all nerve impulses and bodily functions, resulting in a lessening of inhibitions and negatively affecting a consumer's ability to concentrate and stay alert.

When driving during unfavorable weather conditions, avoid slamming on the brakes and making sharp, quick turns. These behaviors will make controlling your vehicle in inclement weather even more difficult.

Drivers are responsible for making sure their vehicles do not become hazards after they have been parked. Wherever you park, make sure your car is visible to drivers approaching from any direction.

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 it is difficult to see due to darkness or poor weather, increase your following distance. This will give you more time to react to hazards that you may not see in advance.

Even if you are facing a green traffic light, do not start across the intersection if there are other vehicles blocking your way. If you are caught in the intersection when the light changes to red, your vehicle will block cross traffic. You can get a ticket for blocking an intersection.

Make room for vehicles that are entering a freeway. If possible, merge into the next lane to create a gap for the incoming vehicles. If you cannot merge, adjust your speed to allow for the vehicles to enter traffic as smoothly and safely as possible.
