The Texas Department of Transportation has activated the Ice Plan Command Post at Transguide, where crews are monitoring the weather and road conditions.

TxDOT officials said in a news release that road crews are on standby to treat overpasses and bridges in addition to responding to emergency situations in the San Antonio area as necessary.

If the event of icy conditions, TxDOT plans to use the following types of materials to prevent or minimize ice formation on overpasses and bridges:

  • A liquid ice control agent is used in an effort to prevent ice from forming
  • A granular ice control agent may be used for more severe ice conditions
  • Crushed rock (called chat rock) will continue to be used to improve traction

Sleet or freezing rain can make driving extremely hazardous. TxDOT advises motorists to avoid driving and stay at home. If motorists must get on the roads, please use extreme caution and remember the following safe-driving tips:

  • Reduce speed. Speed limits are based on normal road and weather conditions, not winter road conditions
  • Maintain at least three times the normal following distance
  • Use extra caution on bridges, ramps, overpasses and shaded areas as they tend to freeze first
  • If you start to slide, ease off the gas pedal or brakes. Steer into the direction of the skid until you feel you have regained traction then straighten your vehicle
  • If possible, avoid unnecessary travel
