Roundabouts! beyond doubt the thing that causes most problems. No quick simple answer but I’ll try. The real skill is the planning on approach. If you don’t actually need to stop you’ve got a big advantage because forward momentum gives you a couple of seconds you wouldn’t have if stationary.
There are only 2 possible options on approach STOP or DONT STOP
The time to choose the option is approx 10-15 yards before the white line, No earlier
Try to be slow enough to stop but in the correct gear to go (if manual)
You WILL be marked on what you can see as you cross the white line. If there’s a car approaching or on the roundabout with no signal STOP. If not GO. Reading roundabouts is something that takes practice, patience and an amount of natural skill. I could write an entire book about this 1 thing
MAIN PROBLEMS ON TEST ON ROUNDABOUTS
1.Approaching too fast
2. Thinking examiner is impatient and wants me to go (a whole chapter in the book)
3. Worrying because nobody is signalling (let them all go then reassess)
4. Road markings/ lane positioning (talk to trainer)
Most test routes have between 8-12 roundabouts sometimes more. These can be test busters so 1 word is very important- CONCENTRATE
Good luck
