RALEIGH — Under a new plan designed to use the element of surprise to put the brakes on drivers over their limit, the Raleigh Police Department was out and about Friday working to outfox heavy drinkers and the occasional traffic violator.

DWI checkpoints usually mean floods of lights, orange traffic cones, and cars being randomly stopped, but Friday's operation meant extra officers patrolling Raleigh's streets focusing on people suspected of driving while intoxicated.

Unlike a stationary checkpoint, the roving patrol gives officers flexibility; they can cruise the streets and change locations at a moment's notice. Officers also have to rely on their instincts and their drunk-driving detection training.

Sgt. Mike Alexander of the Raleigh Police Department says the roving patrol is for good reason.

"There have been some increased accidents out there in the evening hours," Alexander said. "And some of them have been alcohol-related."

For some motorists, the roving detail is like a safety net.

"I like the fact that Raleigh police appear to be everywhere, I feel safe," says motorist William Reed. "Drivers know they can't drink and drive or speed in Raleigh."
