A 42 year old Chatham man was caught at an OPP R.I.D.E. check Wednesday night.
Chatham OPP say the man was stopped at their checkpoint on Communication Rd shortly before 11 p.m.
They suspected he had been drinking so they took him to the detachment office where further tests confirmed their suspicions.
Shane Mullaly was charged with having more than 80 milligrams of alcohol in his blood.
He was later released with an October 17th court date.
