A holiday weekend RIDE Program in LaSalle appears to show drivers are following the rules.
Late Friday night and early Saturday morning, LaSalle Police was set up at two locations in the town.
More than 370 vehicles were stopped, but just one driver was asked for a roadside breath test and passed.
Warnings were issued for burnt out headlights and document infractions, but no licenses were suspended.
LaSalle Police are reminding drivers not to drink and drive this Labour Day weekend.
