Have another one, New Yorkers — the city wants to be your designated driver during March Madness.

The Department of Transportation is giving out 2,000 free single-ride MetroCards and 3,000 $15 prepaid debit cards — which work in yellow cabs, some livery cabs and mass-transit systems, like the subways — to discourage drunken driving.

Officials will distribute the cards on three nights during the NCAAs — tomorrow and March 22 and 31.
