Drivers who leave their vehicles sitting idling in Vancouver for more than three minutes could face fines following the passage of a new city bylaw on Tuesday.

The anti-idling bylaw takes effect immediately, but enforcement won't begin for another six months.

City councillors say they see the bylaw as a tool that gives bylaw officers the chance to educate drivers on the problems associated with prolonged idling.

When the tickets are issued, car drivers will face fines of $50 and truck drivers will be hit with fines of $100.

The city hopes the bylaw will reduce emissions of greenhouse gases and other contaminants, while also reducing fuel consumption, noise and car theft.

The bylaw does not apply to emergency vehicles, buses that are loading or unloading passengers or armoured cars.

City officials say they expect most of the enforcement will happen through complaints from private citizens and businesses.
