Arizona: DMV Practice test

Excessive vehicle speed can have disastrous effects. As a vehicle's speed increases, the potential impact of a collision also increases, elevating the possibility of serious injury and death. Increase your following distance as your speed increases to ensure that you will be able to stop safely if needed.

Before returning to your original lane after passing, you must make sure you are not dangerously close to the vehicle you have just passed. When you can see both of the vehicle's headlights in your rearview mirror, you may have enough room to return to the lane.

Motorcycles can be easily hidden in a vehicle's blind spot or missed in a quick look due to their small size. Drivers of cars must always be alert and looking for motorcycles, mopeds, and scooters.

If two vehicles arrive at the same time to an intersection that has stop signs on all corners, the vehicle to the right has the right-of-way.

When driving in fog, you should slow down and use your low beam headlights. If the fog is so bad that you cannot see, pull off the road and wait for the fog to clear.

If you start to feel tired while driving, drive to the first available rest stop or service area to take a break, nap, stretch, or change drivers. You should not rely on caffeine pills or energy drinks, as these are not a replacement for rest and may make your driving even more dangerous.

Yellow lines separating lanes of traffic indicate that traffic is moving in opposite directions. Double solid lines indicate that passing is not permitted from either direction.

Before changing lanes, you should check your side mirrors and look over your shoulder to make sure it is safe to proceed.

If an oncoming driver fails to dim their high beams, you should avoid looking directly at the headlights. Instead, look toward the right edge of your lane and watch the oncoming vehicle out of the corner of your eye.
