Three "Steps" of Pre Trip Inspection

1) Vehicle Overview

2) Check Engine Compartment

3) Start Engine, Inspect inside cab

Steps of a Pre-Trip Vehicle Overview

Review the last vehicle report. Any items which affect safety must be reported to carrier, and fixed. Things that do not affect safety must be certified by carrier. Sign only if defects were noted.

Checking the Engine Compartment involves three categories:


1) Fluid levels

2) Belts


Types of Vehicle Inspection
1) Pre-Trip Inspection 2) During a Trip (3) Post Trip Inspection/Report

All states are connected to one computerizedsystem to share information about CDLdrivers.
The states will check o n drivers' accident records and be sure that d rivers do not have more than one CDL.

What are some wheel and rim problems you will need to inspect for?

Damaged rims, rust around nuts, missing components, mismatched or bent parts, wheels or rims that have had welding repairs

Rust around the nuts of a wheel may indicate...

That the nuts are loose. Check tightness.

Some risks of inflating tires...

if the wheel and tire are not properly assembled, the lock ring may fly in your direction, eviscerating you! The tire can explode if you over-inflate, causing hearing loss/death!


What are some brake defects to watch for?

• C racked drums.

• Shoes or pads with oil, grease, or brake fluidon them.

• Shoes worn dangerously thin, missing, orbroken.

What are some steering system defects to watch for?

-Missing nuts, bolts, cotter keys, or other parts.

• Bent, loose, or broken parts, such as steeringcolumn, steering gear box, or tie rods.

• If power steering equipped, check hoses,pumps, and fluid level; check for leaks.

• Steering wheel play of more than 10 degrees(approximately 2 inches movement at the rimof a 2 0-inch steering wheel) can make it hardto steer.

What is the suspension system?

The su spensionsystem holds up the vehicle and its load. It keepsthe axles in place. Ther efore, broken suspensionparts can be extremely dangerous.

What is a spring leaf in the context of a suspension system?

 An elliptical spring used to suspend the load from the frame.

An elliptical spring used to suspend the load from the frame.

Why are leaf springs still used?

Though leaf springs have been replaced by coil springs for most uses, heavy commercial vehicles still use leaf springs because of their ability to more evenly distribute loads, rather than coil springs, which transfer the load to a single point.

What problems might you look for with a spring hanger system?

Spring hangers that allow movement of axlefrom proper position.

• Cracked or broken spring hangers.

• Missing or broken leaves in any leaf spring.

• Broken leaves in a multi-leaf spring or leavesthat have shifted so they might hit a tire orother part.

How can you tell if a shock absorber is leaking?

Inspect shock absorber for moisture. A certain amount of "oil mist" is normal. If there are clear traces of oil, then the piston is worn out from long use, severe operational demands, or dirt collection in the shock absorber. And should be cleaned out.

What are some additional benefits of leaf springs over coil springs?

"On a vehicle with longitudinal leaf springs, such as a Hotchkiss drive suspension, the springs themselves provide some longitudinal wheel control. One or more torque arms may be added to provide supplementary wheel control, particularly for vehicles with strong torque such as drag racers."

What components of a suspension system should you examine as part of your pre-trip inspection?

Torque rod or arm, u-bolts, spring hangers, orother axle positioning p arts that are cracked,damaged, or missing. • Air suspension systems that are damagedand/or leaking. • Any loose, cracked, broken, or missing framemembers.

Can a broken exhaust system let poisonous fumes into the cab or sleeper berth?

Yes. Maintain the exhaust system. Check for:

• Loose, bro ken, or missing exhaust pipes,mufflers, tailpipes, or vertical stacks.

• Loose, broken, or missing mounting brackets,clamps, bolts, or nuts.

• Exhaust system part s rubbing against fuelsystem parts, tires, or other moving parts ofvehicle.

• Exhaust system parts that are leaking.

Must a vehicle by equipped with emergency equipment by law?

• Fire extinguisher(s).

• Spare electrical fuses (unless equipped withcircuit breakers).

• Warning de vices for parked vehicles (forexample, three reflective warning triangles).

What cargo preparation must occur before a trip?

Cargo (Trucks). You must make sure the truck isnot overloaded and the cargo i s balanced andsecured before each trip. If the ca rgo co ntainshazardous m aterials, you must in spect for pro perpapers and placarding.

How many steps are in a pre-trip vehicle inspection?

Seven steps.

1) Vehicle Overview

2) Check engine compartment

3) Start Engine and Inspect Cab

4) Turn off engine and check lights

5) Do Walk-around inspection

6) Check Signal Lights

7) Start the Engine and Check

What should you do prior to your pre-vehicle inspection?

Approaching the Vehicle. Notice generalcondition. Look for damage or vehicle leaning toone side. Look under the vehicle for fresh oil,coolant, grease, or fuel leaks. Check the areaaround the vehicle for hazards to vehiclemovement (people, other vehicle s, objects, low hangingwires, limbs, etc.).

Do an engine check the same way every time, so that you are less likely to miss a step.

Safety Inspection. Drivers of trucks and trucktractors when transporting cargo must inspect thesecurement of the cargo within how many miles of a trip?
....the first 50 miles of a trip and every 150 miles or every three hours (whichever comes first) after.

What must you always do before checking the Engine Compartment?

Check that parking break is on/wheels are chocked, so the car doesn't roll!

What is Step 2 of a pre-trip inspection?

11 steps.

Check the Engine Compartment

(check brake)

• Engine oil level.

• Coolant level in radiator; condition of hoses.

• Power steering fluid level; hose condition (if so equipped).

• Windshield washer fluid level.

• Battery connections, and tie downs (batterymay be located elsewhere).

• Automatic transmission fluid level (may require engine to be running).

• Check belts for tightness and excessive wear(example: alternator, water pump, air compressor)--learn how much "give" the belts should have when adjusted right, and check each one. Belts should deflect no m ore than½ to ¾ inches.

• Leaks i n the engine compartment (fuel,coolant, oil, power steering fluid, hydraulicfluid, battery fluid).

• Cracked, worn electrical wiring insulation.

(close hood)

What is the important final step of checking an Engine Compartment?

Close and secure the hood or engine compartment door!
