Arizona CAR DMV Practice Test 15

A green arrow means "go." You must turn in the direction the arrow is pointing after you yield to any vehicles, bicycles, or pedestrians who are still in the intersection.

With decreased visibility and the glare of oncoming headlights, you cannot see as far ahead at night as you can during the day. Always use headlights and exercise caution when driving in the dark.

Drivers must obey special signs or instructions given by flaggers. They are in place to keep drivers and workers safe.

If a road has four or more lanes with two-way traffic, drive in the right lanes unless you are passing or turning left. If you are on an interstate highway and are driving below the speed of the flow of traffic, use the right lane.

If you notice that the road ahead is covered by heavy smoke, reduce your speed immediately, drive as far as possible to the right, and stop off the roadway. Only then should you determine if it is safe for you to continue. Remember that certain kinds of smoke can irritate your eyes and lungs or even kill you.

When you wish to change lanes or make a turn, signal to inform other motorists of your intention. Signals should be activated at least 100 feet before you make the turn. Continue signaling until you have completed the turn or lane change.

This sign indicates that U-turns are prohibited. You may see a sign like this at an intersection that commonly has oncoming traffic.

It is necessary to follow farther behind a large truck than you would if following a passenger vehicle because trucks have larger blind spots.

Treat a flashing red light the same as a stop sign. Come to a complete stop at the stop line or, if there is no stop line, prior to the crosswalk and before entering the intersection. Yield to all other traffic and pedestrians.

When driving at night, change your high beam headlights to their low beam setting when within 200 feet of another vehicle ahead of you.

An octagonal sign always means stop. When approaching a stop sign, you must come to a complete stop at the marked stop line and proceed only when it is safe to do so. If there is no stop line, stop before the crosswalk. If there is no crosswalk, stop before the intersection at a point from which you can see oncoming traffic.

To do your part to prevent road rage, you should follow laws, signs, signals, and pavement markings. Always signal your intention when changing lanes.

To prevent hydroplaning, lower your speed in response to wet roads and keep your tires in good condition. If you detect a loss of control, take your foot off the gas, do not apply the brakes, maintain the direction of the vehicle, and allow the vehicle to slow to a manageable speed.

When turning left from a one-way street onto another one-way street, you should begin the turn from the far left lane.

Allow for extra space when driving behind a motorcycle. Motorcycles can stop more quickly than other vehicles can and you must have adequate room to stop if the motorcyclist brakes or falls off. Also, remember that motorcycles are difficult to see at night because they only have one tail light.

If you see an emergency vehicle approaching while using its flashing lights, pull over to the right edge of the road and stop. Position yourself parallel to the curb. On one-way streets, drive toward the road edge nearest you.

Never assume other drivers will give you the right-of-way. Yield your right-of-way whenever it helps prevent collisions.

You must turn on your headlights any time conditions prevent you from seeing other vehicles. Other drivers may have trouble seeing you, too.

Safe use of the interstate demands drivers be constantly alert and capable of driving at high speeds.

The only way to sober up after drinking alcohol is to allow time for your body to eliminate the alcohol in your system. Nothing you can do, including eating and drinking, can accelerate this process.

When passing another vehicle, move back into your original lane only when you can see the passed vehicle’s headlights in your rearview mirror. This ensures that you will have enough room to safely pull back in front of the other vehicle.

To stay aware of hazards, you should scan the road and check your rearview mirrors every two to five seconds. Constantly staring at just the road ahead of you is dangerous. If you must drive in foggy conditions, you should use your low beam headlights, not your high beam headlights.

When traffic permits, you should make room to allow vehicles to merge into your lane.

Warning signs are usually yellow with black markings. This sign indicates the presence of a crosswalk, regardless of if it is marked on the pavement or not. Upon seeing this sign, you should be alert and allow any pedestrians to cross the road safely.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers that another road crosses the highway ahead.

Both hands should be placed on opposite sides of the steering wheel. This position is comfortable and promotes safe turning on high-speed roadways.

When driving near a blind pedestrian, using your horn may be dangerous. Yield to the pedestrian and proceed when it is safe to do so.

Driving too slowly can be dangerous because it may cause drivers behind you to become frustrated and make dangerous moves to pass you. It is safest to drive with the flow of traffic, within the legal speed limit.

Use low beam headlights when driving in fog, rain, or snow. High beams may reflect off of the weather and make visibility even poorer.

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited. You should match the speed of traffic, unless the speed of traffic exceeds the legal speed limit.
