Found out some interesting information today.
There is a Roadside Assistance phone number located just above the bar code on the back of your licence in the lower left hand corner of it. You can get free roadside assistance from the State of Texas.
I received an email telling me about it and tried to find it on snopes and on the Texas Government web site to no avail but I did speak to a lady here at work that has used it. She said the wait was long but that they came out to her truck and took care of the problem she was having.
Thought you fellow Texicans might want to know.
