A citizen report has led to the arrest of an impaired driver Wednesday night.

Police were alerted by a citizen to a suspected impaired driver at a McDonald's drive-thru at Queenston and Nash Roads shortly before 8 p.m., police say.

The citizen reported to Operation Lookout, a year-round awareness campaign that encourages citizens to phone 911 or the OPP when they see a suspected impaired driver.

The driver showed signs of impairment by drug when officers found him and was arrested, according to the police.

A search revealed that the man had a quantity of methamphetamines. He was then taken to the police station for a drug evaluation and failed all tests, police say.

A 38-year-old man from Hamilton is charged with impaired operation by drug and possession of a controlled substance. He was held for a bail hearing.
