CDL exam with the examiner you can get

one of three forms the front of the

vehicle the side of the vehicle or the

trailer no matter what form you get on

the class a tractor trailer you always

have to do the coupling devices your

external light operation check and your

end cap so let's start with the front of

unique items before we start our

external light operation check

once you have completed the pre-trip

inspection on the outside of the vehicle

the next step is to do an external light

operation check depending on what form

you get whether it's the front form side

form or the trailer form of the vehicle

for your inspection that's where you

will do your light check your examiner

will read you the instructions you'll

hop in the truck and start your light

check so I'm going to hop in the vehicle

to start with the front of the vehicle's

external light operation check

when you get in the truck you want to

brakes

once the air settles out

I'm going to start my lab test

step number one

I'm going to hold my foot on the brake

for one minute

and I have to count that minute or have

the examiner count that minute

and while I hold my foot on the brake I

do not lose more than 4 PSI of air in my

my minute is up I counted to a minute I

did not lose more

then four PSI of air in my air tanks

it's a good test next up we're going to

check the alarm and buzzers I'm going to

Fan my foot brake my service brake till

around 60 to 40 PSI alarm and or buzzer

should come on to indicate that I have

low air in my air tanks let's do that now

my alarm and buzzer did come on that

works properly

now we're going to move to the final

step the buttons my emergency spring

break should come on while I'm Fanning

my brake to 20 to 40 PSI to indicate

that those work also let's move to the

my buttons both popped out around 20 to

40 PSI that was a successful test we're

going to move on to start the vehicle

build the air back up to do the service

brake and the parking brake test let's

do that now make sure the vehicle is

neutral your brakes are on foot on the brake

brake

start your truck

to build the air quicker we're going to

hit the accelerator a little bit to

around 10 or 12 RPM and we're going to

move that air pressure to build much

[Music] foreign

foreign [Music]

trucks the air pressure takes longer to

build than other trucks

so we got to get to at least 100 PSI of

air at the minimum or more before we

start the service rate test [Music]

now that we're around 100 PSI of air

working to do our service brake test

the way we do that we put our foot on

the service brake put the vehicle in

Drive release the parking brakes now

we're going to accelerate to about five

miles per hour or 10 or 20 feet and see

if the service brake actually stops the vehicle

we're going about five miles per hour

I'm gonna hit the service brake

it did stop the vehicle also the vehicle

did not sway from left to right or right

to left to indicate a suspension problem

now we're going to put the vehicle

neutral pull both parking brakes out

next we're going to test our parking

brakes we'll start off with a tractor

brake we're going to put our foot on the

service brake put the vehicle in Drive

release a trailer brake to test the

tractor brake leave the tractor brake on

I'm going to hit the accelerator a little

little

to make sure that the parking brake for

the tractor holds it does hold we're not

going anywhere

now I'm going to put my foot back on the

surface brake

pull out the trailer brake

push in the tractor brake now we're

going to test the parking brake on the

trailer same thing get your foot off the

service brake hit the accelerator a

little bit

to make sure we're now moving and we are

not so it's kind of a tug test to make

sure that your parking brakes do work

now we're going to put our vehicle back

in neutral

pull the brakes back out

now I feel that I have completed my

entire pre-trip exam properly

and I'm going to tell my examiner I'm

done with the exam now if you do

something wrong you forgot an item you

can go back to it your examiner will let

you do that also on the lab test if you

did something wrong

you forgot to do your leak or your

alarms or buttons ask the examiner can I

restart my laptops they will let you

restart the lab test start your truck

build your air restart it from scratch

so we have completed the in-cab

inspection and that's your pre-trip on

the class a tractor trailer thanks for watching
