How do you make a complaint about a driving instructor? Not a complaint about their teaching, more their conduct on the road. I had a learner pull out in front of me on a roundabout this morning, nearly drove into them, so I tooted, and got given the finger by the instructor, then the w*nker hand signal. Had to follow them along the road, next roundabout they slowed to a crawl all the way round it, more hand 'signals', then we came upto some temp lights, they stopped so hard, think emergency stop, I nearly drove into them again. So I went to get out and have a word, saw it was a female instructor and thought better of it, got given more hand signals, then they drove off. I'm not going to complain to the driving school as its a 1 man band sort of thing and don't think I'd get anywhere, I've had a look online for how to complain to the DSA but cant find much about it.
