Worked examples

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

Example 1

What should you do when you're using a contraflow system?

  • A. Follow other motorists closely to avoid long queues
  • B. Increase speed to get through the contraflow more quickly
  • C. Switch lanes to make better progress
  • D. Choose an appropriate lane in good time ✓ correct
Explanation: In a contraflow system, you'll be travelling close to oncoming traffic and sometimes in narrow lanes. You should get into the correct lane in good time, obey any temporary speed limit signs and keep a safe separation distance from the vehicle ahead.
Example 2

What should a motorcyclist avoid at a mini-roundabout?

  • A. The painted area ✓ correct
  • B. Taking 'lifesavers'
  • C. Using signals
  • D. Turning right
Explanation: Avoid riding over the painted area of a mini-roundabout, as this can become very slippery - especially when wet. At any given moment, only a small part of a motorcycle tyre makes contact with the road, so any reduction in grip can seriously affect stability.
Example 3

You're riding in town at night. The roads are wet after rain. How will the reflections from wet surfaces affect your safety?

  • A. They'll make it harder to see unlit objects ✓ correct
  • B. They'll make it easier to see unlit objects
  • C. They'll make it harder to accelerate
  • D. They'll make it easier to stop
Explanation: After rain, the reflections from wet surfaces will make it hard to see unlit objects. Make sure that your visor or goggles are clean, so your vision is as clear as possible. Pedestrians will be difficult to see, especially if they're wearing dark clothing.
Example 4

What lights should you use if you're riding at night on a busy main road?

  • A. Rear fog lights
  • B. Dipped-beam headlights ✓ correct
  • C. Daytime running lights
  • D. Main-beam headlights
Explanation: If there's other traffic on the road at night, use your headlights on dipped beam. Only switch to main beam when you will not dazzle other road users. At night, do not wear tinted glasses or contact lenses, or use a tinted visor, because these make it more difficult to see the road ahead.
