Two people are facing impaired driving charge after separate incidents in Chatham last night.

Authorities responded to a two-vehicle crash on Queen Street last night and say one of the drivers had more than twice the legal limit of alcohol in his system.

Meantime just after 2 this morning, officers found a man asleep behind the wheel of a running vehicle on Joseph Street.

After several attempts to wake up the driver to no avail. Worrying the man might be suffering from a medical emergency, police say they had to break the car window to get in.

The 25-year-old in that case also tested over twice the legal limit.
