Arizona: DMV Practice test - Practice Test 16

Regulatory signs provide notice to road users of traffic laws that must be obeyed. This sign tells drivers that it is prohibited to make a U-turn.

A flashing red light at an intersection means drivers are required to come to a complete stop, yield to traffic and pedestrians, and proceed when the way is clear. The same is true at a stop sign.

Where there are both solid and dashed yellow lines between lanes of traffic, only traffic directly next to the dashed line may cross the centerline to pass. Drivers next to the solid line may not pass.

When being tailgated, create extra space in front of your vehicle and do not brake suddenly. Slow down gradually or merge into another lane to prevent a collision with the tailgater.

Rather than stopping (as you would when entering other roads), you must use the merging or acceleration lane to speed up and smoothly merge with fast-moving traffic already on the interstate.

If multiple vehicles arrive at the same time to an intersection that is not controlled by signs or signals, the driver on the right has the right-of-way. Drivers should then proceed in the order that they arrive to the intersection.

At a green light, you must give the right-of-way to any vehicle, bicyclist, or pedestrian in the intersection. If a pedestrian begins crossing the street after the traffic signal light starts flashing, wait until they have crossed the street before proceeding.

Warning signs are usually yellow with black markings. These signs alert drivers to areas where bicycles may be crossing.

It is illegal to cross the centerline to pass when driving on hills, in curves, and in other locations where you cannot see ahead far enough to pass safely. You may not pass at street crossings, at railroad crossings, where signs indicate no passing zones, or where a solid yellow line is next to your lane. You may not pass when the vehicle in front of you has stopped for a pedestrian or when driving in work zones where passing would be hazardous.
