Re: Cop Braked to Provoke Incident
" "overtaking on the left"
Is this still illegal in the UK today?"
I believe that if you are traveling on an inside lane when someone is going slowly in an outside lane and the road in front of you is clear then it isn't an undertake - you are simply making progress in your lane.
However, if you are behind the car in the outside lane, move to an inside lane to get past them and then return to the outside lane then that is in undertake.
Otherwise everyone stuck in a traffic jam would technically be undertaking when the inside lane starts to flow faster than the outer,
