Niagara Police stopped about 550 vehicles during RIDE spot checks in Niagara Falls Friday night as part of Operation Impact.
Eight drivers were asked to provide breath samples, but none were over the legal alcohol limit, so no criminal charges were laid.
Officers did issue six summonses and seven tickets for various violations.
Those included driving without insurance, using unauthorized licence plates, failing to properly secure an infant and having cannabis readily accessible in a vehicle.
Police also made three impaired driving arrests over the weekend, two involving alcohol and one involving drugs.
