Rise of alcohol interlock devices for DUI offenders in the US

According to a report, The 2013 Survey of Currently-Installed Interlocks in the US, which is conducted by Impact DWI, Inc., there are nearly 305,000 ignition interlock devices currently installed in the United States.  The use of interlocks has increased at a rate of 30,000 units installed per year over the past 8 years, while the number of drunk driving fatalities has been decreasing during the same time period.

States with well implemented ignition interlock laws have seen significant reductions in drunk driving deaths.   In Kansas, drunk driving deaths have dropped by 31% due in part to their all-offender interlock law implemented in 2011.  

MADD’s Campaign to Eliminate Drunk Driving launched in 2006, has been a strong voice for expanding the use of ignition interlocks to all convicted drunk drivers. In 2006, just over 100,000 ignition interlocks were installed in the US and only one state, New Mexico, required ignition interlocks for all convicted drunk drivers.  In 2013, the number of interlocks installed has more than tripled and 20 states currently require or highly incentivise the use of ignition interlocks for all convicted drunk drivers.

MADD’s 2014 Campaign strategy is underway to strengthen existing drunk driving legislation and to introduce all-offender ignition interlock laws in the remaining states.

“MADD calls on the 30 remaining states and DC to take action and enact an all-offender interlock laws,” said MADD National President Jan Withers.  “MADD also urges those states that have enacted all-offender interlock laws to fine-tune and close loopholes so all convicted drunk drivers must use an interlock for at least six months prior to regaining unrestricted driving privileges.”
