Air Brake Test W/o Chocks?

Chocks are absolutely not needed. Remember you will constantly be hitting the brakes and during the leak test you will have your foot on the pedal the entire time. This is why putting the truck in gear at the proper time of the test is so critical. Putting the truck in gear is what prevents you from rolling.

I asked the tester if he wanted me to use chocks he said no. When I do my airbrake test, I put the truck in great to prevent it from rolling.

Yea, that should work for manual.

I'll be testing in an automatic though...

You're referring to manual transmissions right?

I'm testing in an automatic.

Works for automatics too. All I drive now is automatics. Put it in drive and it won't roll. Just make sure it's in drive on the instrument cluster. They haven't taught you this in school?

I didn't go to school.

I don't have the time or money.

I just took a few hour long lessons and renting a truck.

Could you explain a little of how that works in an automatic?

Thanks.

Yes, I can but first I'm going to tell you you're going about this all wrong.

I'll preface this by saying I don't know if this is how it works on the state test because I tested in a manual.

You charge up the brakes until the governor kicks.

You turn the truck off, wait for it to shut off completely and then turn the key to the on position so the gauges work.

You hit the brake (part I'm not sure about) and put it in drive. On the panel you need to see it say drive because sometimes It'll stay in neutral. And you have to press the brake otherwise it won't change gear, like a car. The shifter will move, but it'll stay in neutral.

So after I turn the engine off, and turn the key to on position for the gauges, put it into Drive, and that will prevent the truck from rolling, and than proceed with the air brake testing... and that won't affect the testing at all?

Putting it in Drive while the engine is off will act like the wheel chock and the truck won't start moving either, right?

Think I'm understanding you, if I'm not mistaken.

I'm going to try and ask my instructor about doing it like that... I'd hate for one stupid mistake to cause me to fail the test!

Thanks for your help.

Why test in an automatic? You'll have a restriction on your license and most companies are still using manuals

From the things I've come across online... it seemed like many companies have been transitioning to autos.

Maybe it varies per company or type of driving...

But for OTR cross country with the company I have in mind, I think auto should be no problem.

Putting it in drive will have no effect on the brakes. It'll just stop the wheels from rolling because the engine isn't running.
