WHAT is it about the M62  and Friday afternoons?  This year there has  been a worrying  number of  serious incidents on the  motorway, one of the country’s  busiest.There have been at least two accidents  involving fatalities, a tanker crash  which caused major delays and a three  car smash caused when a lorry crashed  through the central reservation. All of  them happened on a Friday.  Yes there have been incidents on other  days. It is inevitable when this  particular stretch of motorway carries  huge volumes across the Pennines as  people commute between towns on a  daily basis.Slow-moving traffic and incidents of  all kinds are a part of daily life for  those who commute in to and out of  Huddersfield.But the concerning factor is that in  recent months, Fridays seem to be the  day when major accidents are taking  place.Is it law of averages, different traffic  patterns as the week comes to a close,  tired drivers perhaps  more distracted  as they near the weekend? The bottom line is surely this. Is there  something that we are missing? Is this  just an unfortunate statistical blip or  are there any lessons to be learned  from a spate of accidents that have  turned Fridays into bleak days indeed. A look at the figures, some input from  the experts and we might discover  whether this  is sadly a series of  incidents which could have happened  at any other time rather than an  indication that Fridays really are days  when our motorway becomes a  particularly hazardous place to be.
