Arizona: DMV Practice test - Practice Test 13

Warning signs are usually yellow with black markings. This sign indicates that you are approaching a steep hill. Slow down and be ready to shift to a lower gear to control your speed and protect your brakes from damage.

A flashing yellow light at an intersection indicates that drivers should slow to a safe and reasonable speed and proceed with caution.

Before changing lanes, check for drivers trying to pass you who may be trying to enter the same lane as you. Look over your shoulder to check your blind spot. You should never attempt to pass or otherwise change lanes in an intersection.

While it can create special problems for large vehicles, strong wind can cause problems for all drivers. Wind can lower visibility by blowing dirt and dust into the roadway, but it can sometimes also physically move a vehicle.

All roads are slippery and dangerous when wet. This sign warns of conditions that can cause a driver to lose control of a car. A driver should slow down when coming upon wet pavement because it takes longer to stop.

Pentagonal signs indicate that you are in or are approaching a school zone and/or school crossing. Be aware of children when driving near a school zone and follow posted speed limits.

At a yield sign, you must slow down or stop, if necessary, and give the right-of-way to crossing or merging vehicles. Yield the right-of-way to any cross traffic that is close enough to cause conflict.

This sign is posted on one-way streets and other roadways where a driver is not allowed to enter. A driver may see this sign if attempting to enter an expressway ramp in the wrong direction.

Yellow lines separate traffic moving in opposite directions. Dashed lines on the pavement indicate that passing is permitted when safe.
