(Harrisburg) - A new law going into effect Friday aims to cut down on drunk driving.
It requires first-time offenders to have breathalyzers installed in their cars—something 48 other states already do.
Car breathalyzers—officially called Ignition Interlock Systems—require drivers to blow into a device to start their vehicle. If the device detects any alcohol, the car won't start, and it'll also register the attempt.
