MAYFIELD VILLAGE, Ohio — Progressive Commercial, part of the Progressive Group of Insurance Companies, finds that crashes involving trucks occur least often at either end of the business work week and mostly in the summer time.

The U.S. insurance giant recently reviewed claims data from crashes involving commercial vehicles it insures. The study looked at “light local” vehicles as well as heavy trucks with a GVWR of more than 16,000 pounds. Light local vehicles insured on a commercial policy included passenger cars, pickup trucks, SUVs, vans and minivans, etc., and trucks would include tractor-trailers, dump and tow trucks, flatbeds, etc.

Fridays Not Good — But It Depends on What You Drive:

Most crashes, the report says, involving light local vehicles happened on Fridays, while the least number of crashes happened on Tuesdays and Mondays (Saturdays and Sundays were excluded from the study). However, crashes involving heavier trucks happened most often on Thursdays and least often on Mondays and Fridays.

January Winter Blues Equals Fewer Crashes:

In the study period, December 2005 had the highest rate of accidents involving light local vehicles insured by the company. The month with the second highest was November 2005. The months with the lowest rate of accidents were January and April 2006. The difference between highest and lowest? The likelihood of light local vehicles being involved in a crash was 17 percent greater in December 2005 than in January 2006.

June 2006 had the highest rate of accidents involving trucks, which was 29 percent greater than the month with the lowest, January 2006.

Trucks Start Earlier, Finish Earlier:

Not surprisingly, about 66 percent of all crashes involving light local and heavier trucks happened during traditional work hours, though most of the crashes involving heavier trucks happened between 6 a.m. and 5 p.m. and those involving light local vehicles started one hour later — 7 a.m. to 6 p.m.

Light local vehicles were involved in most crashes between 12 p.m. and 6 p.m. while heavier trucks were involved in most of their crashes between 11 a.m. and 4 p.m.
