Over rev it will slow the truck down until you shut it off. Unless it is something new they don't count clutching. Now CRST does count the clutching, and will try and make you pay for the clutch if you don't.
double clutching, removes all "shock" from the driveline, not only saves the clutch,But saves u-joints and drive shafts, I learned to drive in a 2 stick gas-burner with a dog on the rear ends, you had to double clutch and could not any mistakes,if you did you had to come to a complete stop and start over
Well with my truck I don't double clutch or float the gears. I just push D at 1st I did not like it but now I love it,going to hate truning this truck in.
I can do both but perfer to float, when I got my cdl the.book says never shift in a intersection and always pump the clutch shift, I complained to the dmv guy so he told me to drive like I normaly do, so I floated and got threw the intersections on the first green light andassed the test on my.first go, when I was with crst on the road test the other hiree had problems tring to.clutch and has no idea what floating was, so when I got in the seat instead of talking to the crst guy I showed the new guy how to do it both ways, I aced the road test and never had to.deal with 28 days of hell learning from some kid that knows less about driving then his mom does about rasing kids to respect elders so drive however you can.to.say safe.
The law when I did my class 1 was you could not shift if hauling hazardous goods on a railway crossing. I normally clutch out and float in, or double clutch, if in traffic. When starting cold and going slow I just float.
That is crossing with or without hazmat. In TN you shift in an intersection during the test? You flunk. BTW auto shift transmissions cannot be shifted crossing tracks either. They need to be placed into the manual mode.
Double clutching has been a big time mind eff in this my 4th day on the road. I'm a perfectionist and when I hear a grind I want to rip my eyes out!
I normally float. Once you know how to do it right, it can actually be beneficial in reducing clutch wear and tear. That being said, you still have to know how to use the clutch if you need it. Off-road sitework driving, for example, can often put you in situations where you suddenly may need to drop three or four gears in one shot, and you'll need to know how to use the clutch for that. Swift was the only company where I had to double clutch for the road test. Well, a guy I drove dumps for wanted me to demonstrate that I could do it, but I floated through that test.
