Oregon DMV Permit Test cheat sheet

Red octagon means STOP: come to a complete stop at the limit line, crosswalk, or before entering the intersection.

Red triangle (point down) means YIELD: slow down and give right-of-way to traffic on the cross road; stop only if needed.

Yellow diamond = warning sign (curve, hill, merge, signal ahead); yellow pentagon = school zone/school crossing.

Orange diamond = construction or work zone; workers present means slow to posted work-zone speed.

Railroad advance warning is a round yellow sign with an X and RR; crossbuck (X-shaped white sign) marks the actual crossing.

Flashing red signal = same as STOP sign; flashing yellow = proceed with caution; steady yellow light = stop if you can do so safely.

A green arrow means you may turn only in the arrow's direction with right-of-way; a red arrow means no turn in that direction.

A sign with a red circle and slash prohibits the action pictured; a green circle sign permits it.

Broken yellow center line = passing allowed for both directions when safe; solid yellow = no passing; double solid yellow = no passing either direction.

At an uncontrolled intersection, yield to the vehicle that arrived first; if two arrive at the same time, yield to the vehicle on the right.

When turning left, yield to oncoming traffic going straight or turning right, and to pedestrians in the crosswalk.

A vehicle entering a road from a driveway, alley, or private road must yield to all traffic already on the road.

At a four-way stop, the first vehicle to stop goes first; ties go to the vehicle on the right.

Right turn on red is allowed after a full stop unless a sign prohibits it; left turn on red is allowed only from a one-way street onto another one-way street.

The posted speed is a maximum for ideal conditions; Oregon's basic speed rule requires a speed reasonable for weather, visibility, and traffic.

Pass on the left; passing on the right is legal only when the vehicle ahead is turning left or there are two or more lanes in your direction.

You must stop for a pedestrian in a crosswalk, and you may not pass a vehicle stopped at a crosswalk.

Use the three-second following rule in good conditions; add one second for each adverse factor (rain, darkness, heavy load, or being followed closely).

Oregon's Move Over law: on a multi-lane road, move over a lane away from stopped emergency or roadside vehicles; if you cannot, slow to a safe speed below the limit.

Pass bicyclists with at least 3 feet of clearance; if you cannot, wait until it is safe to pass.

Bicycles on the roadway are vehicles with the same rights and duties as cars; do not honk at or crowd them.
