The driver of a large tractor / trailer unit followed me under the railway and as soon as he had passed the three vehicles on the opposite side of the road, overtook me and passed the wrong side of the keep left sign on the pedestrian refuge.
Reported to police who took no further action, stating that the driver passed the wrong side of the sign to keep me safe. He could have done that simply by slowing down and not overtaking until it was safe further up the road.
