- A mandatory instruction
- A warning of a hazard ahead (Correct answer)

Correct answer: A warning of a hazard ahead
Triangular red-bordered signs are warning signs (The Traffic Signs Regulations and General Directions) alerting drivers to hazards ahead such as bends, junctions or pedestrian crossings.
Question 2: A circular sign with a red border and a figure of a walker crossing means:
- Pedestrians have priority always
- No pedestrians — they are prohibited from this road (Correct answer)

- A pedestrian zone operates at certain times
Correct answer: No pedestrians — they are prohibited from this road
A red-bordered circle is a prohibition sign; with a pedestrian figure, it means pedestrians are prohibited from that road or section of road.
