Nassau and Suffolk officials have announced heightened DWI enforcement during this Memorial Day weekend.

To emphasize the stepped-up enforcement of anti-drunken-driving laws on Nassau roads, County Executive Edward Mangano drove to a DWI-awareness news conference Friday in a police car. Its rear half was painted taxicab yellow, and on the side was the slogan: "Choose your ride, don't drink and drive."

"This demonstrates your choices if you go out drinking," he said.

In Suffolk, Police Commissioner Richard Dormer said Wednesday that there will be a "comprehensive boating and driving while intoxicated crackdown plan" for the weekend that will include using police helicopters "to spot potential DWI offenders from the air."

Mangano said his marine bureau will participate in perimeter patrols Saturday and Sunday from 10 a.m. to 3 p.m. at the Bethpage Air Show at Jones Beach.
