TRENTON, N.J. (AP) — Gov. Chris Christie has conditionally vetoed a measure that would have overhauled drunken driving penalties and required the use of interlock ignition devices.

In a statement issued Monday, Christie said he wants to “strengthen” the Legislature’s measure and enact stiffer penalties for DUI offenses.

Under the governor’s recommendation first-time offenders with blood alcohol levels from 0.08 percent to 0.1 percent would have their licenses suspended for three months. They would also be required to have an interlock system in place for three to six months.

The system prevents the driver from starting the car until he or she blows into a device. If alcohol is detected the car will not start.

For first-time offenders with blood alcohol levels in the same range, the Legislature’s bill called for a 10-day suspension.
