Calgary police is expanding its mandatory alcohol screening program, meaning all drivers can expect to blow into a roadside device when pulled over or going through a Checkstop.

The expansion will see all frontline officers with Calgary Police Service issued with roadside screening devices.Watch Live at 1:30 p.m
