State police said Trooper Jonathan Nickles was not hurt in the crash, which happened at about 10 p.m. on Route 109 in Medfield.
State police said Milford officers were pursuing Dana Scovil, 36, of Webster, at a high rate of speed after he failed to pull over.
Nickles stopped his cruiser across the median of Route 109 in an attempt to help stop Scovil’s pickup truck.
State police said the pickup truck veered to the left, hitting a car, and then struck the right front of the cruiser. The impact ripped off the cruiser’s front tire.
State police said officers arrested Scovil, who tried to run. He faces a drunken driving charge and a list of traffic violations.
