With the Memorial Day weekend kicking off the “100 deadliest days for teen drivers,” two Bronx lawmakers yesterday proposed cracking down on fake IDs’ users and makers.

State Sen. Jeff Klein and Assemblyman Marcos Crespos think stores should be allowed to purchase devices that can detect fake IDs instead of being fined for selling liquor to those IDs’ users.

The two Democrats also want to let stores confiscate fake IDs, as well as stiffer penalties for anyone caught making fake IDs.

Underage liquor sales are up 73 percent since 2007, said Klein.

The two pols and industry execs launched the “Card Hard Campaign” outside McCabe’s Wine and Spirits on the Upper East Side.
