    I am referring only to coming to a stop -for whatevereason: stop sign, red signal, traffic stopped ahead.

    All of my manual vehicles and motorcycle I place ineutral and coast and brake.

    Always try to avoid coming to a complete stop - hopefully traffic takes off before I get to it or the signal turns green.

    OK...that may be fine for a bike under 1000 lbs or a car/pickup that is anywhere from 3000-8000 lbs. 80,000 lbs is not safe when rolling up to an intersection in neutral. Gearing down is dramatically going to help you to stop. But there is 6 other pages of folks saying this so this is obviously nothing new.

    Thank you.
    Several truckers and two transmission people say it is a matter of preference and how they were taught.

    The transmission guysay the brakes will do the job fine just by themselves leaving everything else out of it. (One transmission guy was a trucker.)
    They also said that one is applying fuel to get engine and gear speeds to match so they go into gear.

    So far, no one has explained why brakes alone aren't enough.
    Also what % of braking the averagengine accomplishes. (That may be difficulto determine.)

    If brakes are designed to effectively stop an 8,000 lb vehicle, can'they also designed to stop an 80,000 lb vehicle?

    No! And this is where you show you complete ignorance and nievety. I suppose you also think it is a waste of fuel when large aircraft use their engines to help slow them down. We should just build 5 mile long runways and let them coast to a stop. Now go drive your lawn service truck and leave the real iron to the people who know how and keep learning every day. You are an idiot. Hate to tell you but someone has to. You are trying to compare apples to taxi cabs. That's how far off base you are. You may just be a troll. How else could anyone be such a simpleton?

    this is how i drive as well. dont try and get a job driving a roadtrain over here in oz unless you drive correctly, because they just will not hire you because you will kill yourself or someone else or the truck or the freight which can be and are worth multi-millions of dollars per load. But i am also talking about drivers here that rely on the brakes far too much and they do have some bad accidents due to it.

    i hear ya pain, but some people have just learnt to drive that way and because they have not yet had a bad accident or know someone that has, they just think it is ok, and really i can understand thier way of thinking, because no one has expalined it correctly to them. I wish I could explain it on here and help safe some lives, but putting it in writing is just too hard.

    Thread was a joke from page one. They yanking everyones chain. I'd like to see them lose their brakes just once! They would never joke around again.

    Being in the right gear will save your brakes and your butt.

    It isn't just about braking, it is about being "in control". When a truck is moving, in neutral, irrespective of the fact he may be slowing down or stopping, if it is in neutral the driver is not in a position of complete control.



    And yes, I vote troll.
