Questions / G road test
Answer first · reviewed August 2026
How fast should I merge on the G test?
Use the acceleration lane to approach the speed of traffic while respecting conditions and choosing a safe gap. Merging dramatically below traffic speed can create risk.
Make it practical
What to do
Look early, build speed decisively, signal, check the blind spot and adjust into the selected gap.
Easy to miss
The common trap
Waiting until the lane ends to discover both the speedometer and the traffic beside you.
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.
