pull in safely when you can, to let following vehicles overtake
Try not to hold up a queue of traffic. Other road users may become impatient and this could lead to reckless actions. If you’re driving a slow-moving vehicle and the road is narrow, look for a safe place to pull in. DON’T wave other traffic past since this could be dangerous if you or they haven’t seen an oncoming vehicle.
B keep well out to stop vehicles overtaking dangerously
C wave following vehicles past you if you think they can overtake quickly
D give a left signal when it is safe for vehicles to overtake you
