Police forces from across the GTA are in Vaughan for two days starting Wednesday for the launch of the 10th annual commercial safety blitz.
Officers are bringing cube vans, big rigs, cargo trucks, and trailers to Vaughan for spot inspections.
By Wednesday afternoon police had pulled several vehicles off the road for violations and they will only be allowed back on with a proper certification.
Common infractions included permit violations, bad tires, wonky brakes, and loads that were not secure.
Last year police pulled 35% of all vehicles during a two day commercial blitz in Milton, which is in line with typical numbers seen over the last ten years.
