Worked examples

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

Example 1

You are approaching a green traffic light and going straight on. Traffic in front of you is stopped and queuing just beyond the junction. What should you do?

A. Only go if your vehicle will clear the junction ✓ correct
B. Drive slowly across the junction
C. Maintain your speed and sound your horn
D. Stop in the junction until the traffic clears

Explanation: Look well ahead and plan your approach to all junctions. Even though the lights are on green, don’t go forward if queuing traffic will cause you to block the junction. Be aware of the length of your vehicle and any inconvenience it may cause to other road users.

A. Powerful brake lights
B. Size of your vehicle ✓ correct
C. Noise of your vehicle ✓ correct
D. The hiss of air brakes ✓ correct
E. Leaving plenty of room
F. Reacting in good time

Explanation: The size of your vehicle can be intimidating, as well as reducing the amount of room left for other road users. Any noise can easily startle horses. You should take care to leave as much room as you can for riders. Keep the noise to a minimum by gentle use of the brakes and, if necessary, stopping and turning your engine off.

Example 3

You are driving a slow-moving vehicle on a narrow winding road. In order to let other vehicles overtake you should

A. wave to them to pass
B. pull in when you can ✓ correct
C. show a left turn signal
D. keep left and hold your speed

Explanation: Don’t frustrate other road users by driving for long distances with a queue of traffic behind you. This could cause them to lose concentration or make ill-judged decisions.

A. Motorway maintenance

C. Blood transfusion ✓ correct
D. Police vehicle ✓ correct
