Worked examples

Here are a few practice questions from this topic. Try answering each before reading the explanation.

Example 1

The traffic light ahead is showing an amber light. Which colour light(s) will it show next?

  • A. Green alone
  • B. Green and amber together
  • C. Red and amber together
  • D. Red alone ✓ correct
Explanation: At junctions controlled by traffic lights, you must stop and wait behind the white line until the lights change to green. You may then proceed unless your exit road is blocked or it's not safe to do so, such as when pedestrians are crossing in front of you. After the green light, the amber light will show on its own for a short period, followed by the red light. When the amber light shows on its own, you should stop, providing it's safe to do so.
Example 2

There are no speed-limit signs on the road. In England, Scotland and Northern Ireland, what would suggest a 30 mph speed limit?

  • A. Street lighting ✓ correct
  • B. Pedestrian islands
  • C. Double or single yellow lines
  • D. Hazard warning lines
Explanation: In England, Scotland and Northern Ireland there's usually a 30 mph speed limit where street lights are less than 185 metres (600 feet) apart. In Wales the limit is 20 mph.
Example 3

When should regular tyre-pressure checks be made?

  • A. When tyres are cold ✓ correct
  • B. When tyres are hot
  • C. After travelling at high speed
  • D. After any lengthy journey
Explanation: Check the tyre pressures when the tyres are cold. Warm or hot tyres may give a misleading reading.
Example 4

You're approaching a junction where the traffic lights aren't working. What should you do when a police officer gives this signal?

  • A. Stop at the stop line ✓ correct
  • B. Stop level with the officer's arm
  • C. Turn right only
  • D. Turn left only
Explanation: If a police officer or traffic warden directing traffic signals you to stop, you must obey them. They'll use the arm signals shown in The Highway Code. If they're controlling traffic where traffic lights have failed, react to their signal as though it had been given by the traffic lights.
