The crash took place around 8:42 a.m., Thursday, Feb. 11, on Watertown Avenue in Southbury, said Southbury Police Sgt. Nadine Amatruda.
Amatruda said the crash took place when the van was traveling northbound on Watertown Avenue at Riverside Street, and the tow truck was traveling eastbound on West Main Street and Watertown Avenue.
The front end of the tow truck made contact with the side of the van, causing the van to go on its side, she said.
