The loops and highways this line covers
Flat tires and dead batteries in San Antonio happen where the miles are: on Loop 410 around the middle of town, on Loop 1604 around the edge, and on the interstates and US highways that cross them.
Summer heat adds blowouts and worn-out batteries. Work zones add nails and screws in tires. Tell the operator the freeway, the way you are facing and the last exit you passed. Many of these roads carry local names, such as the Pan Am Expressway for I-35 and the McAllister Freeway for US-281, so use whichever name you know.
Texas law protects the truck that comes to you: a driver approaching a tow truck or TxDOT vehicle stopped with its lights on has to move over a lane or slow to 20 mph under the posted limit, or to 5 mph where the limit is 25 or less.
TxDOT also runs a free Highway Emergency Response Operator (HERO) patrol on 261 miles of highway in the greater San Antonio area. It is a state program, separate from this line. Full service runs weekdays from 5 a.m. to 9 p.m., with limited service on weeknights and all weekend, and its crews change flats, add air or fuel and jump batteries on the roads they patrol. Off its roads or outside its hours, this line is the other option.
