FRIDAY 13th comes around once more this week and it could be a particularly miserable day for many fleet motorists.

Accidents are more likely to occur on a Friday than any other day of the week according to new research. Experts believe much of the blame is down to a build-up of stress during the working week, which means drivers are unable to concentrate on the road by the time they reach the weekend and make basic mistakes.

The latest survey was carried out by Town & Country Assistance, an Ipswich-based insurance claims management firm that handles 120,000 motor claims a year on behalf of insurers, brokers, and vehicle fleets. Over four years between 1999 and 2002, Town & Country Assistance found that 17.5% of accidents occurred on a Friday on average.

The likelihood of an accident grows during the week, with 16.8% on Monday, 16.9% of Tuesday, 17.3% on Wednesday, and 17.2% on Thursday, before peaking on Friday.

Saturday and Sunday represented just 8.5% and 5.7% of the total number of accidents recorded.
