Components - Crash investigation sites

Crash investigation site sign.

Crash investigation sites are designated safe zones for distressed motorists to relocate to if they are involved in an incident on the freeway.

The sites are intended for use by motorists to exchange insurance information or make emergency repairs to vehicles following a minor collision or breakdown, provided that the vehicle is able to be driven. They are also used as relocation sites by freeway service patrols.

The shoulder of the freeway is not a safe place for motorists to stop. These sites enhance safety by moving pedestrians and stalled vehicles away from high-speed, "live" traffic lanes. They also remove distractions and potential obstacles for other motorists, thereby minimizing secondary incidents.

Most crash investigation sites are located near freeway exits, but are not visible from the freeway. Future plans include sites along freeway off-ramps for easier accessibility.

Blue information signs located along freeway ramps and arterial streets guide motorists to the sites. Common locations are shopping centers, municipal sites, and park and ride lots. The sites are well lit and often include access to a pay phone.

Currently, crash investigation sites are located in the greater Milwaukee area:

I-94 corridor

  • State Patrol truck weigh station near County G
  • Racine County Sheriff’s substation at WIS 20
  • Wisconsin Tourism Information Center on WIS 165
