Q: What should you do if you wish to overtake a long, slow-moving vehicle on a busy road?
Correct answer:
Keep well back until you can see that it's clear
Explanation
If you wish to overtake a long vehicle, stay well back so that you can see the road ahead. Don't get too close to the vehicle, as this will restrict your view of the road ahead. Don't get impatient; overtaking on a busy road calls for sound judgement. Don't take a gamble; only overtake when you can see that you can safely complete the manoeuvre.
