Worked examples

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

Example 1

You're driving a large vehicle. How does its size and design affect the blind spots?

  • A. It will have no blind spots whatsoever
  • B. It will have the same blind spots as other vehicles
  • C. It will have more blind spots than smaller vehicles ✓ correct
  • D. It will have fewer blind spots than smaller vehicles
Explanation: Take the time to check where the blind spots are when driving a vehicle that's unfamiliar to you. Being aware of the limitations of your mirrors will help you take steps to prevent collisions. Always check the blind spots before changing direction. Frequent and proper use of the mirrors will help you to be aware of a vehicle moving into your blind spot.
Example 2

What will happen if you drive too close to the vehicle in front?

  • A. Your view of following drivers will be reduced
  • B. Your view of following drivers will be increased
  • C. Your view ahead will be increased
  • D. Your view ahead will be reduced ✓ correct
Explanation: The closer you are to the vehicle in front, the less you'll be able to see of the road ahead. You must be aware at all times that you'll not be able to see all around your vehicle. This is why you must have an excellent mirror routine and constantly update yourself on what's going on around you.
Example 3

What must you do before you start reversing?

  • A. Change the tachograph mode
  • B. Use an audible warning device
  • C. Look all around ✓ correct
  • D. Remove your seat belt
Explanation: Large or long vehicles have many blind spots. It's vital to check all these areas before starting to reverse and then make sure you keep checking all around while completing the manoeuvre.
Example 4

What should you do before moving off?

  • A. Use your mirrors and look behind ✓ correct
  • B. Signal right with indicator and arm together
  • C. Just use the offside mirror and move away quickly
  • D. Extend your right arm out of the window
Explanation: To make sure it's safe, you must use the mirrors well before you make any manoeuvre. For example, you need to use them before moving off, turning, overtaking, slowing or stopping, opening a door, or changing direction, lanes or speed.
