Arizona: DMV Practice test

A red arrow means "stop." You must remain stopped until a green light or green arrow appears. Do not turn against a red arrow.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign tells drivers to be alert to crossing pedestrians.

Unless there are signs prohibiting it, you may make a right turn on a red light after coming to a complete stop and waiting for other vehicles and pedestrians to clear the intersection.

A round yellow sign indicates that there is a railroad crossing ahead.

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

When following a motorcyclist, allow for at least a three- to four-second following distance. Motorcycles can stop quickly and following them too closely endangers your life and that of the motorcyclist. If the motorcyclist should fall, you need extra distance to avoid the rider. The chances of a fall are greatest on wet and icy roads, gravel roads, and metal surfaces such as bridges, gratings, and streetcar or railroad tracks.

Do not go around or under any lowered gate at a railroad crossing. Once the gate is raised, do not proceed across the tracks until you can see clearly in both directions and are sure there are no trains coming.

When approaching a T intersection while traveling on the street ending at the intersection, you must stop and yield the right-of-way to cross traffic. Only proceed when it is safe to do so.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers that the number of lanes is reduced ahead and that traffic should merge left.
