Are you having trouble negotiating roundabouts?
Redleaf Driver Training would advise you to be thoughtful about when to venture into roundabouts.
This is an advanced skill and should not be attempted until you are reasonably confident with your abilities to steer a vehicle accurately around a cul-de-sac.
Start with single lane roundabouts.
Initially STAY CLEAR OF DOUBLE LANE ROUNDABOUTS IN PEAK HOUR TRAFFIC.
