Reduce Impaired Driving Everywhere or RIDE is a sobriety testing program used by police in Canada. The program began in 1977 as Reduce Impaired Driving in Etobicoke and the success of the program led to the expansion across the province of Ontario.
The roadside spot-checks usually appear during the holidays to catch drunk drivers, but the program lasts year round. Volunteers are also enlisted to participate in the program.
Police roadside spot-checks are set up on major roadways and off-ramps of highways. Random cars are stopped, and questions are asked. If a driver is suspected to be DUI, the officer may request a roadside breathalyzer test.
