Worked examples
Here are a few practice questions from this topic. Try answering each before reading the explanation.
Example 1
What does this sign mean?
- A. No entry for two-axled trailers
- B. No entry for vehicles with two-speed axles
- C. Maximum gross weight of 2 tonnes
- D. Axle weight limit of 2 tonnes ✓ correct
Explanation: Always look out for road signs, but be especially aware of those that refer to large or heavy vehicles. Get into the habit of checking for signs at junctions. There might be an indication on the junction layout sign. Before you turn, ensure that the road you’re using doesn’t have any restrictions for the vehicle you’re driving.

What does this sign mean?
- A. The width of the road is 6 feet 6 inches (2 metres)
- B. No vehicles over 6 feet 6 inches (2 metres) wide ✓ correct
- C. No vehicles over 6 feet 6 inches (2 metres) high
- D. Trailer length must not exceed 6 feet 6 inches (2 metres)
Explanation: You must always be aware of the size of your vehicle. Look out for road signs that show a width restriction. There should be an indication of this at the entrance to the road. Don’t get into a situation where you have to reverse out of a narrow road because you haven’t seen a sign.
Example 3
Having just overtaken a motorcyclist on a motorway you MUST always check the
- A. speedometer
- B. left mirror ✓ correct
- C. right mirror
- D. road ahead
Explanation: When overtaking with a long vehicle it is very important to be aware of the position of the road user you are overtaking. You must carefully check the nearside mirror to ensure that you have passed safely before returning to the left. Motorcyclists require special attention as they are more vulnerable and may be affected by buffeting from your vehicle.

- A. brake
- B. change gear
- C. overtake ✓ correct
