Pretrip in Winter

Also in cold the air is heavier, thus any exhaust leaks tends to stay low to the ground more.

 

Exhaust gases are hot, particularly compared to ambient air in the winter, also, carbon monoxide is lighter than air, particularly in winter temps. That is the reason carbon monoxide detectors are mounted(when mounted properly) near the ceiling of buildings, the gas rises then builds downward against the ceiling, thus providing early detection.

 

He was kidding probably. Haha

 

Tests questions have one answer, regardless of the reality.

It's going to be exhaust system first, then all the clamps and couplings on the rest of the truck. If it gets cold enough something is going to leak. Main air feed to the intercooler and turbo comes to mind.

You wont last a hour while asleep in a truck with carbon monoxide filling it. It will replace all of the oxygen being carried by your red blood cells until you die from suffocation. That wont take long at all. Or get a monstrous headache and get woken up if you are lucky.

Im not here to start a fight over real world and test answers, refer to my first sentence. Study and learn that first. Worry about the real world once they let you out of the kinder with a fresh CDL with a whole lot more to learn.

 

As long as you have no air leaks in system, brakes are good, lights are good, and tires are good. And your brakes are not froze to drums your ready to roll out.

 

The Steering is not exactly that important. I think we should already be inching into the age of electrically driven steering servos etc.

There is nothing on a 18 wheeler that is ... excess of what is absolutely needed for the task of rolling 40 ton at highway speeds. Excepting perhaps the piles of micromanagement emanating from dispatch. he he he.

 

I did that one night, the #### thing screamed.

Turned out I was on the lowest corner downwind of all the other trucks after careful thought in peace. Yanked the batteries. Waited until someone moved from a upwind spot. Grabbed that and managed to have a quiet detector most the night. Until the wind shifted towards morning...

Tossed it. The detector. #### thing is too sensitive.
