常见问题

Are road signs on the permit test the same in every state?

Mostly yes. Every state uses the federal MUTCD, so shapes, colors and symbols are the same. A few signs and rules vary, so also read your state driver handbook.

What do the colors of road signs mean?

Red means stop or not allowed, white signs give rules, yellow signs warn, orange marks work zones, green gives directions, blue shows services and fluorescent yellow-green marks school, pedestrian and bicycle areas.

Which road sign shapes should I know for the test?

Know the octagon (stop), downward triangle (yield), diamond (warning), pentagon (school), pennant (no-passing zone), circle (railroad ahead) and crossbuck (railroad crossing).

How many sign questions are on the permit test?

It depends on the state. Some states have a separate signs section and others mix sign questions into the main test. Check your state's DMV page.

What is the difference between a STOP sign and a YIELD sign?

At a STOP sign you must always stop completely. At a YIELD sign you slow down and stop only if you need to let traffic or pedestrians go first.
