Today got caught up in a hold up on M5 at Junction 20 approx 2:15pm. Five vehicle pile up on north bound side. The crawler lane was marked closed by overhead gantry sign (red cross), the three outer lanes were restricted to 50mph. A grey Audi A6 "06" registered (CA reg. therefore from south east Wales.) estate with a new caravan on tow went belting up the closed lane and on reaching the accident tried to force his way out into the main stream of traffic in front of me. With the disaster of a weekend that I have just experienced I blasted him on the horn as I could not move out to the next lane and he was then forced to stay put until he could get out. I thought good enough for you as he had broken the law by driving passed three red stop crosses on the over head gantries. Thoght that he was above the law and to hell with the others driving in an orderly and legal manner. What would you have done in the circumstances?
