Highway Bill Interlock Mandate

The 2009 Highway Bill, currently being debated in Congress, has an extreme ignition interlock mandate that would force every state to punish all first-time DUI offenders with an in-car breathalyzer, even if they were just one sip over the legal limit.

MADD has been lobbying for similar interlock mandates at the state level across the country, but few states have acquiesced to their demands. MADD has since convinced their allies in Congress to mandate ignition interlocks on the federal level.

What is wrong with Congress’ interlock mandate?

Congress needs to amend the Highway Bill to target high-BAC and repeat-offenders
