pickens writes "Starting yesterday in New York state, anyone sentenced for felony or misdemeanor DWI, whether a first-time or repeat offender, will have to install an ignition interlock in any vehicle they own or operate. The interlock contains a breath-checking unit that keeps the car from starting if the offender's blood-alcohol level registers 0.025 or higher, a little less than one-third of the legal limit. 'The addition of ignition interlocks will save lives in New York state,' says State Probation Director Robert Maccarone, who led the team that wrote the regulation. 'It's been proven in other states. New Mexico realized a 37 percent reduction in DWI recidivism.' Whether that will be enough to persuade more people to take a cab or find a designated driver is unknown. 'It's one more thing to make people think, it may help — it may keep a few people from getting behind the wheel,' says Onondaga County Sheriff Kevin Walsh."
