The ERSI, along with study sponsors U.S. Fire Administration and U.S. Department of Justice, encourages emergency responders, leaders, standards development organizations and policy makers to read this study.

Effectiveness of Green Strobes on Winter Maintenance Vehicles and Equipment

Snow removal and deicing activities are performed by roadway agencies to enhance winter mobility and safety.  Due to slower travel speeds during these operations, low visibility and reduced pavement friction, safety and collision avoidance remain persistent concerns.  To improve the visibility of winter maintenance vehicles, the Michigan Department of Transportation (MDOT) has added green lights to the warning system of winter maintenance trucks (WMTs) since 2016.  This study investigates the degree to which the visibility can be affected by including these green lights.
