On a recent drive from Dallas to College Station, I noticed my bf flashing his lights at truckers after we passed speed traps. I noticed a lot of truckers acknowledged the signal with a friendly wave...It's something I've known about for a while know, but I was wondering exactly how common the knowledge is. Have yall ever heard of things like that, little curtesies that make long drives a little nicer? Like...
-Flashing your lights to warn of speed traps
-Flashing your lights to let a trucker know they have room in front of you
-Pulling onto the shoulder to allow passing (not something I do, but I appreciate it when others do...although it's pretty dangerous)
I was wondering if these are regional rules, or if it's a pretty widespread thing...I do know that Texas drivers are the friendliest of any state I've been to :)

Ya we do the same in california, and after some one lets us know it is clear to get over we usually turn the four ways on to thank them. Its a trucker thing that most real truckers all know. There is alot of little trucker things like that, I just dont do it to cars because chances are they would miss interpret it or something. Another way to tell them there are cops ahead with out a cb would be to give a peace sign, wich means peace officer ahead. Most truckers know exactly what it means.

they really can't teach the speed trap warnings in drivers ed.

Drivers education here is a joke compared to other countries. In germany it's much more money and much harder.
