We were on the side of I-35 when our truck blew the trans seal about 18 months ago. A trooper pulled up, rolled down the window ,and asked me what was wrong. I explained the problem and that we had help on the way and then I told him I was packin' and had a permit. He said"You should have told me before now". He laughed and said "Looks like you got it covered and drove off. He was right.I should have told him first thing.
Hmm... Sounds to me that this was not an arrest, detainment, or routine traffic stop. Seems you complied with the law and advised him of your carrying out of the goodness of your own heart.
