Topeka ? Kansas will require first-time drunken driving offenders to use ignition interlock devices on their vehicles, starting in July.

Gov. Sam Brownback signed a bill Wednesday that strengthens the state’s laws against driving under the influence of alcohol or other drugs. The new law also requires the state to set up a central database of driving-under-the-influence cases to track of offenders’ histories.

Mothers Against Drunk Driving pushed Kansas to make its laws tougher. Last year, federal statistics showed alcohol-related traffic deaths in Kansas jumped in 2009, even as they dropped nationwide.

Current law suspends a first-time DUI offender’s license for 30 days and allows a judge to order use of an ignition interlock for 330 days after that. The new law will mandate 180 days’ use after the suspension.
