Road signs, road markings and traffic signals
This domain checks whether you can read the road quickly and correctly: sign shape and colour, marking meanings, and signal priority. The exam expects recognition under pressure, not just memorisation of names.
Signs and markings
- Warning signs are triangular with a red border and yellow background. They tell you to slow down or prepare for a hazard.
- Prohibition signs are circular with a red border and white background. Mandatory signs are circular with a blue background. Information signs are usually rectangular.
- A stop sign is octagonal and red; a give-way sign is an inverted triangle. At a stop line you must stop completely, even if the road looks clear.
- Double continuous white lines mean no crossing or overtaking. A single continuous line restricts crossing; broken white lines may be crossed only when safe and legal.
- A yellow box junction must not be entered unless your exit is clear. Zebra crossings give pedestrians priority once they are on the crossing.
Signals
A red light means stop before the stop line. Amber means stop unless you are so close that stopping could cause a collision. Green means proceed only if the junction or crossing is clear. A green arrow authorises movement only in the arrow direction.
Worked example
You approach a signal showing amber. Your car is 10 metres from the stop line at 50 km/h, with a dry road. Braking hard could cause a rear-end collision, so you proceed through only because you cannot stop safely. If you were 40 metres back, the correct action is to stop. The decision depends on stopping distance, not on impatience.
Traps
Do not enter a yellow box to “wait” for a gap. Do not treat a green light as an automatic right to proceed into a blocked junction. Do not cross double continuous lines to overtake a slow vehicle. Do not misread a blue circular sign as a warning sign.
