Mounties say you might want to wait a few hours before picking up your car after a night of heavy drinking.
Sergeant Al Leblanc says even if you've slept, it takes a while for the body to break down the booze.
He says waking up and jumping into your car isn't the best move.
He says sometimes people make the mistake of drinking extensively at night and go to sleep for a few hours and then 5 or 6 hours later they think they are ok to drive. Leblanc calls that a big no-no.
Leblanc explains police often set up early morning checkstops to nab those people who had a lot to drink the night before and could still be impaired.
He says RCMP are working to debunk the myth that impaired drivers are only on the road at night.
