How HALT Works
Bexar County’s HALT System – High water Alert Lifesaving Technology – is a tool to warn drivers when there is too much water over the road to drive through safely. HALT uses a sensor to detect rising water. Once the water reaches a certain depth, the system will warn drivers to turn around with either flashing lights or a combination of flashing lights and gates. HALT also sends real-time information to the website http://maps.bexar.org/halt/ so drivers can see which roads are safe to travel. Bexar County worked with High Sierra Electronics, Inc., to implement the system.
