AI Article Synopsis

  • The widespread use of alcohol ignition interlocks can effectively reduce drunk driving among convicted offenders, but the problem persists once the devices are removed.
  • Many convicted drunk drivers fail to install these interlocks, leading to calls for making them standard in all new vehicles, though this approach oversimplifies the complex issues surrounding drunk driving.
  • There is a need for careful consideration before mandating interlocks in all new cars, as technology alone may not adequately address the underlying sociopsychological factors involved.

Article Abstract

Objective: To discuss the implications of widespread implementation of alcohol ignition interlocks.

Method: We base our discussion on data from Finland including crash statistics and surveys collected from criminal justice professionals and general driving population.

Results: Alcohol ignition interlocks are an effective preventive measure against drunk driving when installed in the vehicles of convicted drunk drivers. However, once they are removed from the vehicles, drivers typically return to their habit of drinking and driving. Furthermore, for a number of reasons, the proportion of convicted drunk drivers that install an interlock in their vehicles is quite small. Therefore, many stakeholders believe that the solution to the drunk driving problem will come when interlocks become standard equipment in all new vehicles. However, drunk driving is a complex sociopsychological problem, and technology can rarely offer a solution to such complex problems. Consequently, many aspects of such interventions might be difficult to identify and include in cost-benefit analysis.

Conclusion: We express caution about requiring an interlock as standard equipment in all new vehicles.
