Because it allows a driver's license to be confiscated immediately, punishment is swift and sure. This is an important part of a strategy to separate the offender from the vehicle, but often it is circumvented by offenders who choose to drive, even while under suspension. Although these laws are among the most useful and most popular for targeting drunk drivers, ALR is only effective as part of a systematic approach to deterring hardcore drunk driving. The officer saw the person drive up to the office and come in. The removal of their driver's license had no impact on whether they continued to drive.
Compliance is poor for all licensing sanctions.
And many drivers do not reinstate their licenses even when permitted to do so. Additionally, many of these offenders drive without auto insurance and do not attend treatment programs where such programs are a prerequisite for reinstatement. Just a license suspension and alcohol education doesn't change the behavior of the hardcore. Problem drinkers are drinking and driving. The license sanction is not going to stop them. .
