Making impaired driving arrests quicker and more efficient

The Challenge 

Arresting someone for driving while intoxicated or driving while impaired (DWI) and processing the paperwork is a crucial but time-consuming task for police officers. The National Highway Traffic Safety Administration (NHTSA) asked Westat to see what strategies law enforcement agencies are using to reduce the cost and time of alcohol-related driving arrests, including the use of electronic reporting systems.

Our Solutions 

  • Working with the Traffic Injury Research Foundation, we collected data about DWI arrests to determine what strategies law enforcement agencies are using to reduce the cost and time of processing these arrests.
  • We performed the following
    • Conducted a literature search of publications discussing improvements in the arrests of DWI drivers
    • Identified law enforcement agencies that incorporated electronic arrest processing and reporting systems; these include electronic driver history checks and vehicle identification systems
    • Collected information from agencies on how much time and money they saved from improving their DWI arrest strategies

The Results 

  • We prepared a comprehensive report that described for NHTSA the best practices currently used, and the resulting cost and time savings.
  • This information may help agencies
    • Identify methods to simplify tasks
    • Accelerate identifying, quantifying, and documenting violations
    • Protect law enforcement officers and the public
