Police officers in Windsor and Amherstburg were busy over Halloween weekend, ensuring drivers did not have too much "witches' brew".
Windsor police conducted RIDE (Reduce Impaired Driving Everywhere) programs all day Friday at locations across both municipalities.
Officers interviewed 305 drivers and issued four roadside sobriety tests.
There was also one standardized field sobriety test administered, but there was no word on whether charges were filed.
Earlier Friday, officers laid 72 charges for various infractions, including speeding, driving without insurance, red-light violations, cellphone use, and vehicle documentation offences.
