Most have moved to an APU device. Basically a little generator that runs hvac and stuff so the big motor isn't burning so much fuel.
There's also this: https://www.idleair.com/?mobile=no Which is a billion dollar idea for whoever came up with it.
Dumb question. Do you truckers appreciate when us cagers flash our high beams to let you know it's ok to pull in front after passing? I always do. I try to watch the side mirror to see when they are looking.
I do in the RV. Easy way to tell - they'll flash their hazards a couple times as they change lanes to say thanks (or dim the running lights at night, personal preference thing tho).
With all the idiots driving these days, I'll bet the truckers like all the help they can get. I couldn't imagine driving an 18 wheeler through traffic.
And don't be surprised if they don't notice or just wait until they're more than positive they have the room. Can't trust people.
It has to be frustrating to drive a big truck. As soon as you have enough room to get over, somebody has to squeeze in there.
truth. No matter how much room you leave for following distance there is always that dipshit that gets right in front of you then slows down. So then you're holding everybody else behind you up, and they pass you too cause you can't get around the dipshit. The cycle continues until you just wanna drive that bitch off a bridge.
Most truck drivers do not use their blinkers to ask permission. It is just a courtesy to let the people in the little vehicles know where the big piece of rolling metal is going to go, with or without their consent!
