An erratic driver caught the watchful eye of Chatham-Kent OPP last night.
An officer spotted a vehicle heading down Grand Avenue East in Chatham just after 11 last night and pulled the driver over.
Authorities say the man behind the wheel seemed to have consumed an intoxicating substance. He was arrested and taken to the OPP detachment for a drug test.
The 64-year-old is charged with impaired driving, possession of methamphetamine, and failure to comply with an undertaking.
He was released with a date in court next month.
