Ask your trainer if you're supposed to park your tractor in neutral or the lowest forward gear when you take your DOT road test.
There seems to be some confusion about that.......
Here safe start for dot test is vehicle in neutral, brake set , clutch depressed, check for oil pressure when it starts.
The dot test does cover a lot more and you should have a cdl exam booklet with all the stuff that will be on the test. Here backing was easy. 100' strait back, offset back left or right, not both, and either parallel park or alley dock. I got parallel park which will tighten your cheeks up a bit, but I swung it right in with only one pull up.
Pretrip is a lot different. Vehicle will be hooked already, and you pretrip tractor and trailer hooked up. Air bleed down is the same, but you have to call out the stuff, example, " low air warning light and buzzer at 65psi" . You also have to say tire tread depth is more than 4/32 on front tires, 2/32 on rear, check for condition, "no cuts bulges or abrasions, no cord or fabric showing,"hit tires with hammer or something, cannot kick them with foot.
Ask questions of your examiner. They should ask you if you have any question. I asked if we needed to chock the wheels checking for air leaks, no more than 3psi in a minute with breaks released, which means you have to have brakes off and your in neutral. Guy gigged me during pretrip for all slack adjusters, I said cannot pull out more than an inch but its an inch with brakes released, our brakes where set at this point but he wanted me to say no more than an inch with brakes released.
Good luck, hope this helps any taking dot test.
