Arizona CAR DMV Practice Test 23

Drivers making a left turn must yield to all vehicles approaching from the opposite direction. This includes bicycles and motorcycles.

A single broken line indicates that drivers may cross from either lane to change lanes. Dashed yellow lines alongside solid yellow lines indicate that passing is permitted from the lane next to the broken line, but not from the lane next to the solid line. Only change lanes when it is safe to do so.

You may encounter unexpected conditions in a construction zone. For the safety of yourself, other drivers, and construction workers, drive with extraordinary caution.

The speed at which you should drive your vehicle depends on road conditions, the weather, and the legal speed limit. You may never drive above the legal speed limit. Decrease your speed when anything makes conditions less than ideal.

Continuous hard braking on snow and ice can result in the locking of the front brake, causing a loss of steering. To avoid the need for excessive braking, make sure to maintain an appropriate speed for conditions.

Pavement is particularly treacherous when it first begins to rain. Accumulations of dirt and oil mix with the rainwater, creating a greasy film on the roadway.

On cold, wet days, shaded spots on a roadway can become icy. Shaded areas often freeze before, and thaw out after, the rest of a road.

Watch for any pedestrian who may cross your path. If you see pedestrians near the road where you are driving, slow down and be prepared to stop, if necessary.

A solid yellow arrow means that the protection of a green arrow is ending. If you are turning in the direction of the arrow, you should prepare to stop and yield the right-of-way to oncoming traffic before turning.

There is zero tolerance for alcohol use by drivers under age 21. If you are under 21, the detection of any trace of alcohol in your system will result in stiff penalties, including the suspension of your license for two years.

This sign indicates that a divided highway begins ahead.

An octagonal (eight-sided) sign always means "stop." You must always come to a complete stop at this sign.

It can be hard to judge the speed of oncoming vehicles. They do not always seem to be coming as fast as they really are. Always be sure you can safely change lanes when passing on a two-lane street. If you are not sure of an oncoming vehicle's speed, wait to pass until the oncoming vehicle has passed and you are sure there is enough space for you to change lanes safely.

You should never change lanes within an intersection. Before changing lanes, always look over your shoulder to check your blind spot. Be alert to other drivers moving into the same lane.

If you want to enter the freeway but do not see a space for your vehicle in traffic, slow down on the ramp to wait for a gap. Do not drive to the end of the ramp and wait for a gap or you will not have enough room to accelerate to the speed of traffic before entering the roadway.

When leaving an interstate, you should maintain your speed until you enter the deceleration lane, at which point you should reduce your speed to the exit ramp's posted advisory speed.

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.

This sign prohibits right turns. It is illegal to turn right at an intersection where this sign is posted.

Blind spots are areas around your vehicle that you cannot see with your mirrors. Check your blind spots by turning your head and looking over your shoulder.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers about an upcoming winding road.

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.

When approaching this sign, you must yield the right-of-way. Slow down and let vehicles and pedestrians crossing your path pass before you proceed. If necessary, stop before going ahead.

If you are in an intersection when you see an emergency vehicle approaching while using its flashing lights and/or siren, continue through the intersection and then drive to the right and stop. You must yield the right-of-way to any police vehicle, fire engine, ambulance, or other emergency vehicle using a siren or flashing lights.

When no other limit is posted, the speed limit when approaching a school crosswalk is 15 mph.

Some highways reserve the left lane for vehicles with multiple occupants. These High Occupancy Vehicle (HOV) lanes are identified by signs and diamond pavement symbols.

You may turn left onto a one-way street that moves to the left if there is no sign prohibiting the turn. You may not turn left onto a one-way street where traffic moves to the right.

Your vehicle's stopping distance increases as your speed increases. When driving at high speeds, it is important to look well ahead of your vehicle to allow yourself space to safely react to hazardous situations.

Orange-colored signs indicate construction areas. Proceed with caution.

When passing is permitted, look for both headlights of the passed vehicle in your rearview mirror. Only then may you safely return to your original lane.

If you encounter a severe dust storm, you should immediately reduce your speed, drive completely off the highway, stop as far to the right as possible (taking care not to stop in the travel or emergency lanes), turn off your lights, take your foot off the brake, remain in the vehicle with your seat belt(s) buckled, and wait until the dust storm has passed.
