Guide to Daily Pre-Trip School Bus Inspections

Guide to Daily Pre-Trip School Bus Inspections

A pre-trip inspection is an important daily practice for school buses and other large vehicles. It's essential to ensure the safety of all students on board as well as the bus's performance. A quick inspection usually doesn't take more than a few minutes, but it can make sure that the vehicle is in good condition before the daily journey begins. During inspection, exterior and interior components need to be carefully checked. By performing a pre-trip inspection every day, drivers can avoid any potential problems or safety hazards that could arise if the vehicle is not up to standard. Taking the time for this essential inspection ensures student safety and optimal performance of the bus on its journey.  With the right inspection preparation, your transportation department can function better and safer than ever. Let's get started!

1. Check the mirrors.

Start by checking your school bus's mirrors. This quick step is essential for drivers to ensure that the vehicle's mirrors are all in alignment and positioned correctly. Completing this quick step ensures that the driver has an unobstructed view of their surroundings while driving, making it safer and easier to maneuver within the area.

2. Check the windows and windshield.

Next, check the windows and windshield of the school bus. This step is important to ensure that there is no debris or dirt on the glass that can obstruct a driver's view. Ensure that all windows are securely closed and clean before continuing with the rest of the inspection. If there is any dirt on them, use a window cleaner to remove it before moving on to your next step.

3. Check the tires.

The next step of your pre-trip inspection is to check the tires. It's important to look for any visible signs of damage such as bulges, cracks, and wear. If your school bus has a tire pressure gauge, use it to ensure that all tires have enough air in them for a comfortable ride. Checking the pressure is even more important in the colder months, when pressure can quickly change. Additionally, be sure to inspect the tread of each tire to make sure it is deep enough and not worn down. If you find any issues with the tires, they should be addressed before driving the bus.

4. Check under the bus if there are traces of leaks.

Next, it's important to check under the bus for leaks. This step is important because leaks can cause damage to parts of the vehicle and can also be hazardous for passengers on board. Look for any traces of oil or liquid that could indicate a leak in the engine area or fuel system. If you find any leaks, report them to your supervisor or in your inspection checklist.

5. Check bus interior condition.

Next, check the interior condition of your bus. Look for any signs of wear and tear or damage that could be hazardous for passengers on board. Check to make sure all interior components such as seats, lights, emergency exits, and other equipment are in working order. Make sure the interior is clean and free of any major debris or dirt that can cause distractions while driving. Additionally, look for any signs of water or mold damage that could affect the interior condition and comfort of passengers, especially after any significant rain or snow.

6. Check all engine fluid levels.

Next, it's important to check all the engine fluids of your school bus. This includes checking the coolant levels when the engine is cold and oil levels when it is hot. Additionally, check other fluids such as brake fluid, power steering fluid, and windshield wiper fluid. If you need to add any fluids, make sure to use fluids specified by your bus's manufacturer. It is also important to check all fluids periodically throughout the year as they can significantly affect how well the vehicle runs and how safe it is to drive.

7. Double check for any braking system alerts.

Next, it's important to check for any braking system alerts. Make sure all brakes are working properly and that there are no brakes stuck or brakes that need to be adjusted. Check for any warning lights or indicators on the dashboard of your bus and make sure they are all in the off position. If there is an alert or indicator lit up or brakes not functioning properly, the bus should not be driven until it is inspected by a professional.

8. Check all exterior lights.

Finally, check all exterior lights of your school bus. This step is important to ensure that the vehicle is visible while driving and can be seen by other drivers on the road. Check brakes lights, reverse lights, headlights, turn signals and any other exterior warning lights to make sure they are working properly. If you find that any of these are not functioning properly, replace them with new bulbs before driving the bus.

9. Report any negative findings.

As mentioned above, it is extremely important to report any serious or dangerous findings during your daily pre-trip inspection.  If you find anything that could potentially be hazardous to the passengers or the bus itself, report the findings to your supervisor and do not drive the bus until it has been inspected and fixed. Taking these precautions is essential for ensuring a safe ride for everyone on board.

Pre-trip inspection printable resources, what you need to know about the pre-trip inspection.

The Pre-Trip Inspection is a thorough inspection of the vehicle and all of its major systems. Inspecting the vehicle before driving each day is a Federal requirement and normally takes about 15 minutes. It must be logged in your logbook as "on duty not driving."

You will have to do thorough safety inspections of the coupling system, the vehicle lights, engine compartment, tires and brakes, the chassis, the fuel tanks, and an in-cab inspection.

The following information is a brief summary of Daniel's Complete Pre-Trip Inspection taken from our oustanding free PDF download:

Engine Compartment

engine compartment pre-trip inspection

You will be checking the engine compartment for any sort of leaks. You will also be checking to see if all components are properly mounted and secured. None of the mounts must be cracked, bent, or broken.

You will be checking all hoses to make sure they aren't leaking, frayed, or sliced and the fluid levels including the oil level, the coolant, and the power steering fluid.

You must check the components like the water pump, the power steering pump, and the alternator to make sure nothing is leaking, the belts are not frayed, and that everything is properly mounted and secured.

From inside the engine compartment you will also find the steering system, the front suspension system, and the front brake system. All components of these systems must be properly mounted and secured without anything being cracked, bent, or broken. Finally you will be checking the tires, rims, and axle seals to make sure the tires are properly inflated, the rim isn't bent or cracked, and the axle seals are not leaking.

Fuel Tank And Battery Area

You will be standing where the tractor and trailer are connected and you'll start by checking the electrical line and air lines to make sure they're properly mounted and secure at both ends. No abrasions, bulges or cuts. Not leaking air. Make sure the electrical line has no wires exposed. Check the gladhands to make sure the seals are in good condition, no cracks or signs of dry rotting. Not leaking air.

Check the skid plate of the fifth wheel and the apron of the trailer to make sure there is no debris and nothing is cracked, bent, or broken. Make sure the fifth wheel is properly greased. Also make sure there is no gap in between the fifth wheel and the trailer apron once the tractor and trailer are coupled. Make sure the kingpin of the trailer is properly mounted and not cracked, bent, or broken and that the locking jaws of the fifth wheel are properly secured when the tractor and trailer are coupled.

Check the mounting bolts where the fifth wheel attaches to the tractor frame. Make sure there are no missing bolts and that everything is secured properly. Check the locking pin if you having a sliding fifth wheel to make sure it's properly locked into place.

Make sure that there is the proper clearance space between the tractor mudflap and the trailer landing gear so that they don’t hit each other when making a turn.

You will start inspecting the trailer at the head board, which is the front wall of the trailer. Make sure there are no holes or missing rivets. Check the landing gear to make sure it is properly mounted and secure. Not cracked, bent, or broken. Make sure the fully raised and the handle is secure in the cradle when the tractor and trailer are coupled.

Check the frame and crossmembers under the trailer to make sure they're not cracked, bent, or broken. Check the tandem frame and release pins to make sure the frame is in good condition and the release handle and locking pins are in the fully locked position.

You will check the entire suspension and brake system for the trailer tandems the same way you did for the drive axles of the tractor. You will also make sure the mudflaps are properly secured. For dual tires check to see that there is proper space between the tires and there is nothing stuck between the tires.

Check the rear door and hinges to make sure they are properly mounted and nothing is cracked, bent, or broken. Make sure the door seals are not worn, torn, or dry rotted.

Light Check

You will be checking all of the lights and reflectors on both the tractor and the trailer. Check the reflectors and reflective tape to make sure they are properly mounted and secure, not cracked, bent, or broken, and clean and illuminated. Check that you have the proper color of amber to the front and sides, and red to the rear.

Start by turning on your marker lights and headlights. Now walk around the entire truck and trailer and point out the lights. Give the function of the light and the location. You should then ask your examiner to help you check your five functions.

While you're sitting in the drivers seat, the examiner will stand to the front of the truck, then behind the trailer. He will then check your Turn Signals, Four Way Flashers and Brake Lights. You must do each function at every location.

The five locations that you must check your lights:

  • Front of the Truck
  • Both sides of the Truck
  • Rear of the Truck
  • Both sides of the Trailer

Air Brake Test

in-cab air brake test during pre-trip inspection

The air brake test will consist of a leakdown test to make sure your air brakes aren't leaking air and losing pressure. It will also test the warning lights and buzzer to make sure the driver gets the proper warning if the air pressure drops too low.

There are three stages to an Air Brake Test

#1: Applied Pressure Test

#2: Warning Light and Buzzer

#3 Tractor/Trailer Protection Valve Pop Out

Applied Pressure Test: Build the air pressure to governor cut out. Put the truck in the lowest gear. Then turn off the engine Immediately turn the engine back on. Push in both the tractor and trailer valves. (This will release the parking brakes.) Push and hold the Brake pedal fully. Allow the gauges to stabilize. Announce the gauges have stabilized and the Primary and Secondary PSI. With the Brakes fully pressed, you should not lose more than 4 PSI in one minute. Announce that you are listening for air leaks during that minute.

Warning Light and Buzzer Test: Pump down on the Brake pedal until the warning light and buzzer comes on, at or before 60 PSI.

Tractor/Trailer Protection Valve Pop Out Test: Pump down on the brake pedal until both the tractor and trailer protection valves pop out. They should both pop out between 40 and 20 PSI.

We have a ton of Pre-Trip Inspection Practice Questions along with the answers and a complete scoring system in our Free Online CDL Practice Tests :

The Engine Compartment Section will include questions about checking the oil level and coolant levels, inspecting belt-driven engine components (like the water pump, alternator, and air compressor), and the safety devices required in the cab. There will also be questions regarding the windshield wipers and free play in the steering wheel.

The Lights And Brakes Section will include questions about dashboard indicator lights, inspecting the parking brakes, and doing a leakdown test on the air brakes. It will also include questions about the low air pressure warning signal and testing your air horn and city horn.
