That’s because our roots have been in the traffic safety business since 1958 when the industry was orange as it remains today. After three generations in the traffic safety business, Decker Supply is, without question, the one traffic safety provider you can trust.

It all started when Ken Decker, a 1958 pioneer in the the traffic safety industry, brought his talents to Warning Lites of Illinois in Chicago and later to Northern Signal in Saukville, Wisconsin in 1963. Ken’s passion for traffic safety led his son, Keith and daughter in law, Jane, to establish their own traffic control company in the late 1970s. Their company, Traffic Signing & Marking (TSM) eventually became the largest company of its kind in Wisconsin. A large part of Jane and Keith’s success can be attributed to their own hard work and that of their dedicated employees at Decker Supply.

Keith and Jane’s daughter, Megan Decker, founded her own traffic safety company, Mega Rentals, which is now a hugely successful traffic safety company in its own right.
