The Pennsylvania Senate has passed legislation that will require some first-time offenders convicted of driving under the influence to use interlock devices on their cars.

An ignition interlock device requires the driver to blow into a breathalyzer before it allows the engine to start. The new measure would require anyone caught driving with a blood alcohol content of 0.10%, just above the legal definition of intoxication at a BAC of 0.08%, to have one of the devices installed.
