Work Zone Safety

MDT wants everyone to remember the three S’s of work zone safety: speed, space, and stress. Slow down in work zones and follow speed limits. Leave enough room around your vehicle. Stay calm and pay attention to the road. Be prepared for delays before you leave, download MDT’s mobile app “MDT 511” or visit 511mt.net and check your route. If you're driving and want to check in, pull safely off the road and dial 511. Tune in to local radio stations and watch for variable message signs along the route.

Slow for the cone zone. Give workers a break. Stay alert! Better roads ahead.
