Traffic Signs, Signals, and Road Markings
What this domain tests
The written exam checks whether you can read the road before you move: sign shape and colour, signal priority, and lane markings. Liberia drives on the right and uses English-language signs, with speeds shown in miles per hour. Faded paint is common, so the sign and signal outrank a worn marking.
Core rules
- Regulatory signs tell you what to do: STOP, YIELD, speed limits, no entry, one-way. A STOP requires a full stop at the stop line, then yield; a YIELD requires slowing and giving way, not necessarily a full stop.
- Warning signs are usually yellow diamond-shaped and warn of curves, intersections, pedestrians, or road damage. Guide signs are green or blue and give directions and services.
- Signals: steady red = stop; steady green = proceed only if the intersection is clear; yellow means stop if you can do so safely. A flashing red is a stop sign; a flashing yellow means proceed with caution. If a signal is dark, treat the intersection as an all-way stop and apply right-of-way rules.
- Markings: yellow lines separate opposing traffic; white lines separate same-direction lanes or mark the edge. A solid line means do not cross; a broken line may be crossed when safe. Crosswalks and stop lines are white.
Worked example
You approach a four-way intersection with a flashing yellow light. A car is already waiting at the cross street. You do not have priority simply because your light is flashing yellow: slow down, check for pedestrians, and be ready to yield to traffic already in the intersection or arriving from your right. If the light were flashing red, you would stop completely first.
Traps
Treating yellow as “speed up”; rolling through a STOP when no one is visible; ignoring a dark signal; crossing a solid yellow line to pass; and reading a faded marking instead of the sign.
