Halton police have launched a pilot project partnering with fast food restaurants to help spot impaired drivers going through the drive thru.

The collaboration is part of the wider #Campaign911 and #MakeTheCall911 initiative to get drunk drivers off the road.

Managers and supervisors at 38 participating restaurants are getting tips to educate their employees on how to spot a possible impaired driver. Police have provided laminated posters and an in-house video.

Signs of impairment include inability to navigate the drive thru, the smell or sight of drugs or alcohol, drowsiness, glossy eyes, slurred speech and reduced motor skills.

Members of the public are reminded to call 911 for any suspected impaired driving.
