Halifax Regional Police say they caught someone behind the wheel with four times the legal limit of alcohol in their system last month. That’s the story behind one of 53 drunk drivers police said they charged in April.

Police credited the public with calling in 24 per cent of the drunk drivers. Half of the drivers were caught during patrols, and 13 drivers were charged after a crash.

While one of the drivers was four times the legal limit, four were three times the limit. Another 15 were twice the limit.

Police said two of the cases involved drug impairment.

On May 1, Nova Scotia changed its drunk driving laws. Drivers caught above the limit with children in the car can lose their licence for two years, and be forced to install an interlock device in their vehicle.
