Questions / G road test
Answer first · reviewed August 2026
What following distance should I leave on the G test?
Leave enough time and space to stop safely; increase it in poor weather, at higher speed or behind vehicles that block your view. A rigid number cannot cover every condition.
Make it practical
What to do
Use a fixed roadside point to measure your time gap during practice and notice how speed changes the physical distance.
Easy to miss
The common trap
Drifting closer because the examiner asked for a lane change and you are waiting for a gap.
Turn knowledge into a habit
How to practise it
Build real highway repetition with a qualified supervisor. Merge, change lanes, follow and exit in different traffic instead of saving the entire experience for one mock test.
When a rule, road sign or examiner instruction conflicts with an internet tip, use the official rule and the safe decision. The internet has many talents; wearing a reflective examiner vest is not one of them.
