Drinking + driving = caught, cuffed, car confiscated.

That's the no-nonsense math that came out of City Hall yesterday.

Mayor Bloomberg announced that starting Memorial Day weekend, the city will launch an aggressive summer-long crackdown on driving while intoxicated. Last year, there were 1,971 DWI accidents - and 34 fatalities - citywide.

"If you are thinking about driving while drunk, don't do it because we will take your car and send you to jail. Make no mistake about it," Bloomberg said.

The city will operate 36 sobriety checkpoints. The NYPD Highway Division will station extra units at each of the city's principal entrances, and foot patrols will be on the lookout for reckless drivers.

The drunken-driving vehicle forfeiture program, begun in 1999 under former Mayor Rudy Giuliani, has resulted in the seizure of 5,460 cars, including 647 this year.

The NYPD also will step up seat-belt enforcement, said Police Commissioner Raymond Kelly, who warned, "If you are caught not wearing a seat belt, you will be pulled over, summonsed and fined."
