    Been driving 9 years accident free.
    And I don't understand why safety guys at most companies I worked say this:
    "Don't use engine brake on wet roads or in the snow".
    I just ignored them and especially use those jake brakes in winter conditions - helps me to slow down gradually, nice and easy.
    So my truck went to shop on wednesday and I got one of those newer kenworth trucks as a loaner until sunday.
    Had to drive it thru western PA last night - quess what? If you turn the wipers on the jakes won't work !
    I am the only one using engine brakes in winter?
    Do you guys use it in bad weather??

    Absolutely I do. Some conditions I don't but to think that any time you need the wipers you shouldn't use the brakes is desk driver absurdity.

    I can't even imagine the frustration that must cause, getting into a piece of equipment that won't let you use it how you want to.

    IT is equal to having the rear breaks lock up on wet or on icy roads, you slide.

    I know, I've done it on a skid pad.

    You never tried to play an original 8-bit Nintendo, did you?
    This machine is the root of my youthful disappointment with things, particularly machines. Lol.

    I have used engine brakes loaded (heavy) only, and very carefully when it is raining, never in the snow, I never do if I am empty or light. Ridgeline is exactly the reason I was told to do it this way. It can break the traction of your rear wheels and cause a jackknife accident. No trailer equals e-brake on a dirt road. It's that tiny little bump that starts at the engine brake, slowing the engine, forcing everything behind it to slow down. That little bump having traveled back to the rear end and wheels, is what will cause traction to break. The wheels don't even need to lock up. If it's slick enough, just that little bit of rolling hesitation will send you in to a slide.

    I think that wiper disabling engine brake is just silly. There must be some setting in that trucks computer that can change that. With everything else they can make these trucks do no reason to believe otherwise.

    One day. One day the OP will discover there are some slick conditions that the "reverse torque" from the engine brakes is sufficient to lock up the drives. And when this happens in a curve I'm going to laugh myself silly.

    But excluding their use with wiper use is dumb but I'm sure this was brought about by a bunch of poorly taught drivers who did not know basic engine brake usage protocol and perhaps had the same misguided understanding as the OP. [Read the owners manual for further clarification]

    Kind of ironic, huh. The one complaining may be part of the reason behind the subject of the complaint.
