The document summarizes Ontario's Commercial Vehicle Impoundment Program, which impounds commercial vehicles found with critical defects to improve road safety. Under the program, vehicles are impounded for a minimum of 15 days for the first incident within 2 years, with longer impoundment periods for repeat offenses. Vehicles can only be released after all impoundment costs are paid and repairs are made to address critical defects. The goal of the program is to encourage operators and drivers to properly maintain commercial vehicles and conduct pre-trip inspections, in order to reduce collisions and increase road safety.
