STS's roots are in underserved areas not receiving the proper service needed when there is a turn-head situation in their area. The citizens have been relied upon as the safety "alarm" for the Department of Transportation ("DOT"), but the residents of these areas, in particular, are less likely to make that call.

When founder, Scott Bradley, a Los Angeles DOT TSR and master electrician, noticed that by the time the DOT was finally notified, the turnaround on turn-head service calls was weeks instead of days or hours. The longer it takes to correct these safety issues, the chance of an accident occurring increases dramatically. This results in unnecessary expense to city budgets, and even worse, innocent lives.

​

Scott knew he had to find a way to remove the public as a notification system, which was proving heavily flawed and potentially costly and dangerous. He conceived and developed an active sensor that could send an alarm to the DOT electronically when turn-head activity occurs providing the opportunity for the issue to be fixed right away. This concept and in turn product proved to be a winner when a 6-week municipality trial lasted more than a year and had a 99.9% success rate, showing new response times of about one hour as opposed to the previous 3 weeks.

Since then, STS has continued to grow year after year and in 2020, STS was able to onboard a new partner, Ben Reynolds, to help manage the company's newfound success in a dual role as the CFO/COO; and has partnered with Vision Zero Network, an organization that is working and pushing to have zero traffic deaths by 2035.
