Worked examples
Here are a few practice questions from this topic. Try answering each before reading the explanation.
Example 1
You overtake a cyclist on a two-way road. What should you do?
- A. Pass closely staying about 1 metre (3 feet 3 inches) from the kerb
- B. Go past quickly and move back to the left sharply
- C. Leave plenty of room and check your nearside mirror before returning ✓ correct
- D. Use a right-turn signal after pulling out
Explanation: Only overtake when it is safe to do so.Never force other vehicles to move for you. Be patient and stay well back from the cyclist until there is a safe overtaking gap.
Example 2
When are air deflectors most effective?
- A. When there is a crosswind
- B. When there is a headwind ✓ correct
- C. When reversing
- D. When there is a strong tailwind
Explanation: Cab mounted air deflectors and lower panels will streamline the vehicle and it will, therefore, offer less resistance to the air around it. This will decrease its fuel consumption. Conserving energy and resources should be a concern for all drivers on the road.
Example 3
You are in the centre lane of a motorway and overtaking another vehicle. What should you do before returning to the left-hand lane?
- A. Signal left then check your mirror
- B. Wait for the other driver to flash their headlights
- C. Check ahead and then your nearside mirror ✓ correct
- D. Check behind for fast traffic in the right-hand lane
Explanation: Never return to the left-hand lane until you are sure that you are well clear of the vehicle you have just overtaken. Don’t cut in too soon and don’t rely on the other driver flashing you in. Make your own judgement!
Example 4
Long vehicles need to straddle lanes
- A. to avoid mounting the kerb ✓ correct
- B. to avoid braking sharply
- C. when driving on motorways
- D. when coming to contraflow systems
Explanation: When driving a long vehicle around corners it’s sometimes necessary to adopt a different road position to avoid mounting the kerb or colliding with street furniture such as lamp posts, traffic signs, etc. Other road users may not understand what you intend to do next. Watch them carefully and always signal in good time.
