Traffic Signs, Signals, and Road Markings
What to master
Signs are grouped by shape and color, and questions test recognition fast. Octagon = stop. Inverted triangle = yield. Diamond = warning. Pennant = no-passing zone. Rectangle = regulatory or guide. Circle = railroad advance warning. Colors carry meaning: red for stop/prohibit, yellow for warning, orange for construction, green for guidance, blue for services, brown for recreation, white for regulatory. Learn signal meanings, including flashing yellow (proceed with caution) versus flashing red (treat as a stop sign) and a dark signal (treat as a four-way stop if the signal is out).
Traps the test sets
- Confusing a yellow warning diamond with an orange work zone sign.
- Solid versus dashed lines: solid means no crossing; a double solid yellow means neither direction may pass.
- A yellow light means stop if you can do so safely - not "speed up."
- Pavement markings: a shared center left-turn lane is marked by solid and dashed yellow on both sides.
Rule of thumb
Read signs in three layers: shape, then color, then symbol. Most questions can be answered from shape and color alone before you even read the words.
Worked example
You see a downward-pointing triangle at an intersection with no stop line. That is a yield sign: slow, check traffic, and stop only if needed to let others pass.
