TOPEKA, Kan. -

State lawmakers passed a bill Friday that will continue to require convicted drunk drivers to install an ignition interlock system. This is the breathalyzer that requires all DUI offenders to breathe into it before it will start.

The original bill regarding the interlock law was passed in 2011, but was expected to expire in in 2020.

Mothers Against Drunk Driving (MADD) asked lawmakers to remove this sunset clause. Both chambers overwhelmingly passed the bill.

According to MADD, Kansas has seen a 30 percent reduction in the number of drunk driving deaths since the first interlock law was passed.
