In what part of the lane should you ride when being passed by on-coming vehicles?

• A. As close to the centre line as possible.
• B. No special part of your lane.
• C. The centre or left of your lane.
  Explanation:

  "Stay centre-left to give yourself a buffer and to help you stay visible in the vehicle ahead's wing mirrors if it doesn't have a rear-view mirror. Don't ride on the hard left of your lane, though, as there may be looser surfaces there that can be slippery or contain sharp debris that might puncture your tyre."
