Texas Drivers License & Emergency Information Really great Information to know! This was news to me. And trust me, I got my drivers license out and looked. It's really there! Something all Texans should know, especially since this has received very little or no publicity. Your Texas driver's license has a phone number on the back, just above the bar code on the lower left side: 1-800-525-5555. (It's VERY SMALL PRINT, but it IS there.) This number can be called for emergency assistance on the highway or wherever you might have trouble while in your car. A service truck will be sent to you. This service is state operated, paid for with your tax dollars. If you are ever stranded, just call the number on your driver's license...help is on the way. A state trooper will be sent to make sure all is well. This one is worth passing on especially to all the women you know.
