Arizona Permit Test key terms

The legal priority to proceed through an intersection or shared space while others wait. It is never simply taken; it is yielded, and drivers who arrive at the same time follow established order rules.

The rule that you must never drive faster than is safe for current conditions, regardless of the posted limit. Rain, traffic, darkness, or road damage can make the posted maximum too fast.

A maximum speed that applies no matter how good conditions are, such as the limit posted on a highway. Good weather does not authorize exceeding it.

At an intersection where all approaches stop, the first vehicle to arrive goes first. If two arrive at the same moment, the driver on the right has the right-of-way.

The gap you keep behind the vehicle ahead, measured in seconds rather than feet. A three-second gap in good conditions gives you time to react and stop.

The combined distance traveled while you perceive a hazard, react, and then brake to a stop. It grows sharply with speed and with slippery or dark conditions.

A loss of tire contact with the pavement when water builds between them, letting the vehicle slide. Ease off the accelerator without hard braking and hold the wheel straight until grip returns.

The technique of looking and steering where you want to go while easing off the accelerator and avoiding sudden braking. Abrupt inputs prolong a skid rather than correct it.

A braking feature that rapidly releases and reapplies pressure to prevent wheel lockup. In an emergency, press firmly and keep steady pressure while steering around the hazard.

A temporary loss of braking power when brakes overheat, common on long downgrades. Shifting to a lower gear and using engine braking helps prevent it.

A downward-pointing triangle telling you to slow or stop and let crossing or merging traffic pass before you continue. You proceed only when the way is clearly safe.

A solid white line painted across your lane at a stop sign or signal. Stop before it, not on it or past it, so pedestrians and cross traffic keep their space.

The practice of stopping with your front bumper behind the stop line or crosswalk. When no line exists, stop before entering the intersection area.

The portion of roadway set aside for pedestrians to cross, marked with painted lines or left unmarked at intersections. Drivers must yield to pedestrians in it.

The legal obligation of drivers to yield to people walking in a crosswalk or at an intersection. A driver turning across a crosswalk must wait for pedestrians to clear.

A signal that requires a full stop before proceeding when safe, functioning like a stop sign. At a flashing red, normal right-of-way rules apply afterward.

A warning light meaning slow down and proceed with caution. It does not require a stop but signals a hazard such as a busy intersection ahead.

A marking that separates traffic moving in opposite directions and forbids passing when it is on your side. A double solid yellow means neither direction may pass.

A dashed line separating lanes of traffic moving the same direction. You may cross it to change lanes when the move is safe and properly signaled.

A center lane marked by solid and broken yellow lines on each side, shared by traffic turning left from either direction. Use it only to begin or complete a turn, not for travel.

Signaling your intention to turn or change lanes well in advance, then canceling the signal afterward. Signaling does not grant right-of-way; you must still check and yield.

Looking over your shoulder into the area mirrors do not cover before changing lanes or merging. Mirrors alone leave gaps where a vehicle can hide.

The buffer of empty road you maintain around your vehicle on all sides. It gives you room to swerve or stop when another driver makes a mistake.

Operating a vehicle while attention is diverted to another task, such as texting, eating, or adjusting controls. Even a brief glance away at highway speed covers a long distance.

The rule that by driving on public roads you agree to submit to a chemical test when lawfully arrested for impaired driving. Refusal carries license penalties separate from the criminal case.

The percentage of alcohol in the bloodstream, used as the legal measure of impairment. It rises with each drink and is affected by body weight, food, and time.

A standard holding drivers under 21 to a much lower alcohol threshold, often near zero, than adults. Any detectable alcohol can trigger license suspension for a young driver.

An alcoholic beverage container that is open or has a broken seal while inside a vehicle's passenger area. Possession by a driver or passenger can violate the law even without drinking.

Reduced alertness and slower reactions caused by lack of sleep or long hours of driving. It impairs judgment much like alcohol and is a common cause of crashes.

Allowing safe clearance when passing a bicycle and checking for riders before turning or opening a door. Bicycles are vehicles with the same road rights as cars.

The strip beside parked cars where an opened door can strike a cyclist or passing vehicle. Check mirrors and look back before opening your door into it.

The wide areas around a truck, especially along both sides and directly behind, where the driver cannot see your vehicle. If you cannot see the truck's mirrors, the driver likely cannot see you.

The areas around large vehicles where the driver's visibility is limited. Avoid lingering beside or tailgating a truck so the driver can see you and stop safely.

The requirement to stop for a school bus displaying flashing red lights and an extended stop arm, in both directions unless divided by a physical median. Proceed only when the lights stop.

Slowing, looking both ways, and listening before crossing tracks, and never stopping on them. If gates are down or lights flash, stop and wait until it is clearly safe.

Pulling to the right edge and stopping when an emergency vehicle approaches with lights and siren, then resuming when it passes. Never block an intersection while yielding.

The requirement to change lanes away from stopped emergency or roadside workers when possible, or slow down if a lane change is unsafe. It protects people working near traffic.

Proof that a vehicle is legally registered and financially covered for liability, which a driver must carry and show when requested. Driving without either can bring fines and license action.

Checking that required items such as brakes, lights, tires, mirrors, and seat belts work before driving. A defective safety item makes the vehicle unsafe and may be illegal to operate.
