HALT Technology

Bexar County is prone to flash flooding. Within seconds and without warning, drivers can find themselves stranded or even swept away by flood water.

Bexar County's HALT, or High-Water Alert Lifesaving Technology, is a high-tech system to alert drivers of dangerous waters with either flashing lights or a combination of flashing lights and gates.

Tips for Driving in the Rain

Tips for Driving
  • Monitor the news for weather related information. If there is a flash flood watch or warning in effect, stay off the roads.

  • Avoid areas that are already flooded and do not attempt to cross a flooded roadway.

  • Recognize flood-prone areas such as low water crossings, dips and ditches and do not attempt to cross if flooding is possible.

  • Be cautious when driving at night or in unfamiliar areas when it is harder to recognize flood dangers.
