RCMP patrolling a regional highway on Newfoundland's Avalon Peninsula charged a driver Thursday whose blood alcohol level exceeded the legal limit four times over.

Police said the driver's vehicle had crashed late Thursday night on Roaches Line, which connects the Trans-Canada Highway with communities in Conception Bay.

The driver — described by police as "extremely intoxicated" — escaped injury, but not criminal charges.

"On testing he was found to have a shocking blood alcohol concentration of 320 mg%. This is 4 times the legal limit," RCMP said in a statement early Friday.

No one else was hurt in the incident. Police charged the man and then released him for a later court appearance.

RCMP said the incident was one of two calls of drunk driving reported by the public on Thursday.

In Old Perlican, RCMP located and arrested a man whose erratic driving had prompted a call. That man, whose blood alcohol level was twice the legal limit, has also been charged with impaired driving.
