I've had to break the speed limit to allow the police to pass, was on the M26 2 lanes, inside there's a row or 5-6 lorries, I'm starting to overtake when I see in the distance a police car lights flashing catching me up, im doing 80...... its getting real close now and the lorries aint helping me out, so I floor the throttle and i'm soon hitting 100..110..and finally im past the last lorry and pull in, Police car passes me and the copper in the passenger seat gives me a thumbs up, well, I think it was the thumbs up!!
I'd always try and get out of the way, as you just dont know what they are trying to get too!
