The goal was to crack down on unsafe and overweight trucks to protect motorists and limit damage to roads, said highway police, who were assisted by officers from the Sixth Precinct and state Department of Environmental Conservation.

Of the 26 vehicles weighed, seven violated weight limits. Those violations could result in fines totaling $110,000, police said.
