Montreal drivers who don't obey the strict letter of the law are used to keeping an eye our for the familiar white car with blue stripes that mark a police cruiser.

Now they'll have to keep an eye out for black muscle cars as well.

The police force has purchased two 'camouflaged' black Dodge Chargers, and plans to buy several more.

The cars are marked 'police' in faded-out tones on the side with no obvious markings on the front or rear of the vehicle, which the force says is ideal for traffic patrol.

Police say the cars will first be used in the north and west parts of the island in an attempt to nab people using cell phones, speeding through school zones, or other traffic violations.
