SAN ANTONIO – Drivers who travel on Loop 1604 will have to pay close attention to some orange trailers with speed limit signs because the number could change.
The Texas Department of Transportation will begin to test a variable speed limit system next week on Loop 1604 westbound between U.S. Highway 281 and Interstate 10.
TxDOT officials say the speed limit could change depending on traffic conditions.
The default speed will be 70 miles an hour, but if traffic comes to a crawl in a certain location, the speed limit will be lowered for drivers before they reach that backup.
"The idea here is to get traffic to ease into the congestion spots so you're not running along at 70 miles an hour and all of a sudden see that traffic is at a near-stop and all of a sudden slam on your breaks and risk a rear-end collision," Josh Donat, TxDOT Public Information Officer.
Officials say whatever the speed limit sign says is enforceable by law. The variable speed limit pilot program will start next Monday, June 30.
