The laws have been modified several times over the past two decades to expand ignition interlock device (IID) use and increase compliance. In 2009, Washington State created Ignition Interlock Licenses (IIL) and modified the existing ignition interlock laws. The Washington Traffic Safety Commission (WTSC) evaluated the effects of the 2009 law on recidivism and compliance. This report provides an evaluation of drivers who had an IID installed during 2009 under the new laws. Utilizing data provided by ignition interlock vendors and the Department of Licensing (DOL), WTSC evaluated installation compliance, noncompliance behaviors, and recidivism. The evaluation showed: Installation compliance has improved. - An installation compliance rate of 56 percent, higher than the 33 percent compliance rate reported in an evaluation of the 2004-2006 laws. There is a high frequency of driver noncompliant actions after the IID is installed. - Among IID drivers, 8.2 percent started their vehicles either never or rarely (0-9 starts per month). An additional 5.1 percent of drivers exhibited minimum vehicle use (10-19 starts per month). - Overall, 21 percent of interlocked drivers were found to have tampered with the IID at least once. Among drivers who tampered with their IIDs, the average number of tampering attempts was 11.6 times. - Overall, 73 percent of interlocked drivers experienced one or more start failures; the average number of start failures was 10.8. Ten percent of these drivers had 27 or more start failures. The average blood alcohol concentration (BAC) reading for start failures was 0.09. - Failures in random retests occurred for 37 percent of all drivers with an average of 1.6 retest failures. The average BAC reading was 0.06 for retest failures. - Vehicle lockouts occurred among 25 percent of the drivers, with an average of 1.32 lockouts. The IID significantly lowered recidivism among second and third-plus DUI offenders. - Among first driving under the influence (DUI) offenders, no significant difference in recidivism was found between the IID drivers and non-IID drivers. Differences in age and prior driving history between IID drivers and non-IID drivers did not affect the results. - Among second DUI offenders, there was a significant difference in recidivism between the IID drivers and non-IID drivers. Second DUI offenders with an IID had a 26 percent lower recidivism rate. - Among third-plus DUI offenders, there was a significant difference in recidivism between the IID drivers and non-IID drivers. Third-plus DUI offenders with an IID had a 28 percent lower recidivism rate. Details: Olympia, WA: Washington Traffic Safety Commission, 2014. 19p.
