Traffic Signs, Signals, Pavement Markings, and Work Zones
What this domain tests
This domain tests recognition and application of signs, signals, pavement markings, and work-zone rules. The exam expects instant meaning plus correct driver action.
Core rules
- Sign shape and color carry meaning: octagon means stop, inverted triangle means yield, diamond means warning, pennant means no passing, and rectangle can be regulatory or guide.
- Red means stop or prohibition; yellow warns; orange marks work zones; fluorescent yellow-green marks school, pedestrian, or bicycle areas; white and black are regulatory.
- Solid yellow center lines separate opposing traffic; broken yellow allows passing when safe; double yellow prohibits passing. White lines separate same-direction traffic or mark edges.
- A flashing red signal is treated as a stop sign; a flashing yellow means slow and proceed with caution.
- Work zones use orange signs and may double fines for moving violations when workers are present. A flagger's directions override signs and signals.
Worked example
A driver sees an orange Road Work Ahead sign, then a flagger holding a slow paddle. The driver must slow immediately and follow the flagger, even if the permanent signal is green, because the flagger controls the temporary traffic pattern. Speeding in the posted work zone can carry doubled fines.
Traps that cost marks
Do not confuse a broken yellow line with permission to pass blindly; visibility must be clear. Do not treat a flashing yellow as a stop. Do not ignore temporary markings because permanent lines are still visible.
