The next morning I could have done with a lie in. And if I'd know before I set out that a lorry was going to dump its load across the M6 then I would have done. Instead the new lights were flashing and we weren't moving.
So the great expensive system that got put in now meant we had 4 lans of stationary traffic and no hard shoulder for the Emergency services to use. I reached junction 10 at 10am and got off and made a back way round to junction 9 where behold the motorway was empty - unlike my bladder.
