Signs & Signals
Learn the visuals and controls that show up fast on test day.
Start with the rules the exam expects you to recognize instantly: regulatory signs, warning signs, pavement markings, lane arrows, and signal colors. This module is about fast identification and the action each control demands, so you can move from guessing at symbols to reading the road the way the handbook expects.
The rules that matter
- Shape and color tell you the rule before you read a word: an octagon is always stop, a triangle is always yield, a diamond is always a warning.
- Yellow means stop if you can do it safely. Speeding up to beat the light is the wrong answer on the test and on the road.
- Flashing red works exactly like a stop sign. Flashing yellow means slow down and proceed with caution.
- A green arrow protects your turn; a green light does not. On a green ball you still yield to oncoming traffic and to pedestrians.
- A solid yellow line on your side means no passing. A solid white line means stay in your lane.
- Right on red is allowed after a complete stop and yielding, unless a sign prohibits it — and some cities ban it outright.

Where these rules come from
We do not copy official handbooks — most states do not allow it. What we do instead: state the rule in our own words, then name the official document behind it. 130 questions in this module cite 28 official documents, none checked earlier than 2026-05-17. The 6 most-cited are below.
