Reduce Impaired Driving Everywhere or RIDE is a sobriety testing program used by police in Ontario, Canada.
The roadside spot-checks usually appear during the holidays to catch drunk drivers, but the program lasts year round.
Officers from participating police forces are usually members of traffic and auxiliary units.
Police roadside spot-checks are set up on major roadways and off-ramps of highways.
The Supreme Court of Canada ruled that the random roadside checks do not violate the Charter as long as they are carried out for the purposes of the R.I.D.E.
