Leandra's Law/Ignition Interlock

LEANDRA ROSADO  09/06/1998 - 10/11/2009

Leandra Rosado, an 11-year-old girl, was killed on the Henry Hudson Parkwayin New York City on October 11, 2009 when her friend's mother, Carmen Huertas, lost control of the car they were in while allegedly under the influence of alcohol. The car, driving 68 miles per hour in a 50 mile per hour zone, flipped over on the highway. Six other children were also injured during the incident. Huertas pled guilty to all charges filed against her and was sentenced to four to twelve years in prison on October 29,2010 

Leandra's father, Lenny Rosado, lost his only daughter that day and vowed he would travel to Albany and not leave until changes were made to the existing DWI laws.  

On November 18, 2009, New York State enacted Leandra's Law named after Leandra Rosado. Leandra's law gives New York the toughest drunk driving punishments in the country. It's now an automatic felony to drive drunk with a child under 16in the car - punishable by up to four years in prison, even for first-time offenders.

The New York bill also mandates the use of interlock devices for any convicted offenders. The devices are connected to a car's ignition system and require a breath test before the car will start.

A 2009 study found repeat drunken driving offenses dropped 64 percent among those with interlock devices and wider implementation could save 750 lives a year.

An ignition interlock is a technology-based device that attaches to a person’s vehicle and requires a “clean” breath sample in order to start the car. If a person has been drinking, the device will be able to detect alcohol through the breath sample provided and will disable the vehicle’s ignition system. Once that person is sober and no alcohol is detected in the breath sample, the vehicle will start and operate as normal. All test failures are reported to the court or designated agency, however, so an offender will face additional penalties for attempting to drink and drive. That means that not only is the driver safe from harm, but, any passengers in the car or other drivers on the road are safe, as well. With “Leandra’s Law” and similar programs across the U.S., there are fewer risks for any child and adult to be injured or killed due to a drunk driver.
