Arizona: DMV Practice test

When driving, do not develop a fixed stare. Frequently check your rearview mirrors so you know the positions of vehicles near you.

You should adjust your speed to travel smoothly with the other traffic on a roadway (provided that the other traffic is driving within the posted speed limits). Remember that vehicles moving in the same direction at the same speed cannot hit each other. Crashes involving multiple vehicles often happen when some vehicles are traveling at different speeds than others.

You should always change lanes gradually and carefully. Only change lanes when necessary. Every lane change increases the possibility of a traffic accident.

Alcohol slows your reflexes and reaction time, reduces your ability to see clearly, and makes you less alert. As the amount of alcohol in your body increases, your judgment worsens and your driving skills decrease. You will have trouble judging distances, speeds, and the movement of other vehicles.

When driving, watch for warning signs of fatigue. You are too tired to drive safely if you are struggling to keep your eyes open, drifting from your lane, or turning up the radio and rolling down your windows to keep yourself awake. If you notice these signs, it is a good idea to find a safe place to park so you can refresh yourself with a short nap.

Downward-facing triangular signs mean drivers must yield. When approaching a yield sign, slow down to a speed that is reasonable for existing conditions and stop if necessary. If you must stop, do so at a marked stop line, if it exists.

Even if your vehicle is properly equipped with mirrors, there are blind spots that cannot be seen by using the mirrors. Before changing lanes, look over your shoulder to check these areas.

Warning signs are usually yellow with black markings. This sign warns drivers that they are arriving upon a fork in the road and they must bear either right or left.

This sign indicates that you may not make a U-turn. You cannot turn around to go in the opposite direction at an intersection where this sign is posted.
