Apr 30, 2018 - MANDATORY INTERLOCKS FOR ALL DUI OFFENDERS SAVE LIVES, NEW RESEARCH FINDS


Laws that require all offenders driving under the influence (DUI) to install alcohol interlocks reduce the number of impaired drivers in fatal crashes by 16 percent. If all states without such laws adopted them, something like 543 additional lives could be saved each year.

Those are the highlights of a new study released last month by the Insurance Institute for Highway Safety, a nonprofit financed by the insurance industry.

Alcohol interlocks are in-vehicle breath-testing units that require a blood alcohol concentration (BAC) below a certain level, typically somewhere between 0.02 and 0.04 percent, before the vehicle can be started.

More than a quarter of U.S. crash deaths occur in crashes in which at least one driver has a BAC of 0.08 percent or higher, according to the report. Forty-five states require them for at least certain impaired-driving offenders. Twenty-eight states, the District of Columbia and four California counties have some type of interlock requirement that applies to first-time offenders.

"We looked at the number of alcohol-impaired passenger vehicle drivers involved in fatal crashes over time and compared them with the number of drivers in fatal crashes that didn't involve impairment," Eric Teoh, a senior statistician with the institute and the paper's lead author, said in a statement.

The analysis indicated that the number of impaired drivers (with BAC .08% or higher) in fatal crashes drops:

--3% when states have laws that require interlocks for repeat offenders only

--8% when states require interlocks for repeat offenders and first offenders with high BACs
