Police say a man is facing an impaired driving charge after attempting to prove to his friends that he wasn't drunk.

Peel Regional Police allege the man was drinking at a bar early Wednesday morning and set out to show his friends he wasn't impaired.

It's alleged he drove to a Mississauga, Ont., police station to prove his point.

Police say he asked for a breath test and officers obliged.

A police spokeswoman says his blood-alcohol level was allegedly one-and-a-half times the legal limit.

A 32-year-old Caledon, Ont., man has been charged in connection with the incident.
