Michigan DOT implements first all-wet reflective work zone standard in the nation

Michigan’s Department of Transportation (MDOT) had been using wet reflective optics in its permanent pavement markings on certain larger construction projects for years when officials decided to establish a standard to require full wet reflectivity in its work zones. MDOT wanted to increase safety and visibility in construction zones, where changing lane assignments combined with rain and darkness can make it difficult to see temporary markings without wet reflective optics.
The guideline mandating the use of temporary wet reflective tape and paint in work zones is the first of its kind in the country and went into full effect in 2017, according to MDOT Work Zone Delivery Engineer Chris Brookes.
