You keep well back while waiting to overtake a large vehicle. What should you do if another car fills the gap?

Explanation: When following a large vehicle, you need to keep well back to help you to see around it. You can only judge whether it's safe to overtake when you have a clear view of the road ahead. If another vehicle comes past you and fills the gap, drop further back to keep a safe separation distance.
