Decided to bimble up the M5 rather than take the A roads to get to work this morning...bad choice! Quite literally 1/4 mile from my junction the police closed the motorway right in front of us because of an accident just before the exit slip. Nothing to do but wait it out - we got going again within 45 mins so no real harm done. The accident looked like a three car rear-end shunt, only one ambulance in attendance and no mention of it in social media today so I assume no bad casualties...
