Truck Pre-Trip/Inspection

Pre – Trip Inspection 

This slide program was designed to 

assist personnel with their pre – trip 

inspection 

This slide program comes with an 

outline that can be used for preparing for 

the pre-trip inspection. It includes all 

department Class B material 

This slide program is designed to help 

you complete an accurate and 

systematic pre-trip check off

This slide program will cover each of the main 

areas of the morning check off 

This slide program will cover all the 

components in each of the main areas 

Component locations can change on different 

types of truck manufactures 

Start with the Brake Test inside cab, once 

completed start the In Cab Inspection. When 

the check off is completed start on the outside 

with Engine Compartment – Drivers Side and 

work in a clockwise order.

The Main Areas Consist of 

Air Brake Test – (Inside Cab)

Air Brake Check Inside Cab 

 

 

 

 

Start air test 

• Place chock block against down hill side of the rear wheel 

• Prior to starting engine , pump service brakes until air gauges read 

about 70 – 80 psi. 

• Start engine (Ensure Tillerman is in bucket on Deadman switch) 

Max air 

• Build air pressure to maximum 120 to 130 psi (at idle) 

Governor cut out 

• When air pressure stops rising (at idle) – air dryers may release 

• Give reading for both primary and secondary air gauges 

• The maximum cut out pressure is 130 psi 

Governor cut in 

• Pump service brake pedal slowly (push and hold for 3 seconds , then 

release and wait for 4 seconds , then repeat if necessary) until 

governor cuts in. The minimum cut in pressure is 85 psi. Continually 

watch air gauge needles for upward movement. 

• If gauges do not move upward (governor cut in) , continue to pump 

brakes slowly (as above) release about 5 psi. each time until governor 

cuts in. 

• The gauges will start to move upward 

• Give reading for both primary and secondary air gauges 

• Build air back to maximum

Static air Test – 2/60 single 

vehicle Place vehicle in low 

gear (manual shift 

transmission) 

• Place vehicle in neutral 

(Automatic Shift 

transmission) 

• Shut down engine (turn 

off engine) 

• Release emergency / 

parking brakes 

• Wait for system to settle 

• Note and verbalize 

Primary and Secondary 

air gauges 

• Time 1 minute (60 

seconds) 

• Gauges should not drop 

more than 2 psi / 60 

seconds = single vehicle

Applied air test – 3 / 60 

single vehicle 

• With emergency / parking 

brakes still released 

• Apply and hold service 

brake pedal for 1 minute 

• Wait for system to settle 


primary and Secondary 

air gauges 

• Time 1 minute (60 

seconds) 


Primary and Secondary 

air gauges 

• Gauges should not drop 

more than 3 psi / 60 

seconds = single vehicle

Low air warning 

• Turn on key / ignition 

• DO NOT start engine 

• Pump service brake pedal 

slowly (above) until LOW 

AIR buzzer / light activates 

• Note and verbalize Primary 

and Secondary air gauges 

• Should activate at between 

the minimum and maximum 

of 55 psi to 75 psi 

• above 

Pop out test – Emergency 

valve check (older vehicles will 

be pulled in) 

• Pump service brakes pedal 

slowly (as above) until 

emergency valve pops out 

• Emergency activation 

should be around 45 psi and 

no less than 20 psi 

• Note and verbalize Primary 

and Secondary air gauges

Air recovery 

 

• Start engine (Ensure Tillerman is in bucket on Deadman 

switch) 

Max air 

• Bring engine to 1200 RPM 

• Build air pressure to 85 psi 

• Verbalize start time 

• Build air pressure to 100 psi at 1200 RPM 

• Verbalize stop time 

• Note air should build and recover within 45 

seconds from 85 psi to 100 psi at 1200 RPM 

• This will assure that the air compressor is building 

air at the normal rate

Tug test 

• Remove chock block 

• Buckle seat belts 

• Build air pressure to maximum (cut out) 

• Apply emergency brakes valve only – release all other 

brakes 

• For manual transmissions 

○ Put transmission in low gear 

○ Slowly release clutch 

○ Gently tug against emergency brakes 

For automatic shift transmissions 

• Put transmission in “D” Drive 

• Gently tug against emergency brakes 

Apply column (trolley / hand ) brake valve ONLY 

– release all other brakes including emergency 

brakes

For manual shift transmission 

• Transmission in low gear 

• Slowly release clutch 

• Gently tug against column brakes 

• Release column (trolley / hand) brake 

For automatic transmissions 


• Gently tug against column brakes 

• Release column (trolley / hand ) brake

Service brake test 

• For manual shift transmissions 

○ All personnel fasten seat belts 

○ Put transmission in low gear 

○ Slowly release clutch – start vehicle moving 

○ Lift hands from steering wheel (Instruct Tillerman to also lift 

hands from tiller wheel) 

○ Apply service brakes pedal sharply 

○ Note any movement left or right and equal adjustment of 

brakes 

For automatic shift transmissions 

• All personnel fasten seatbelts 


• Start vehicle driving 

• Lift hands from steering wheel (Instruct Tillerman to 

also lift hands from tiller wheel) 

• Apply service brake pedal sharply 

• Note any movement left or right and equal 

adjustments of brakes

Complete air test 

• Apply emergency / parking brakes 

• Transmission into neutral 

• Brake check is complete 

• Keep engine running 

• Start in cab inspection
