How many kinds of inspections are there?

• There are 3 types of vehicle inspections
• Pre-trips … done every working day before you start driving
• On the road inspection or in route
• After the first 50 miles
• Whenever a change in duty status is made
• And every 150 miles or 3 hours
• Post trip inspection (this is the one you must document on you Driver Vehicle Inspection Report or the DVIR)

What is the point of all these inspections?

• The driver must be satisfied that the vehicle is in a safe operating condition & meets all safety requirements
• If the vehicle doesn’t meet DOT safety requirement, don’t drive it. Get It Fixed First.

Tips for doing a good inspection as quickly as possible

• First start at the same place every time you do an inspection. The driver’s door for instance.
• Work your way around the truck in the same direction every time
• Always check under the hood …

What should be checked under the hood?

• Fluids like coolant, and washer fluid
• Belt and hoses for signs of wear
• Nuts and bolts for rust leaking out

How do you keep from missing something?

• Always check everything … it’s the thing you skip that will cause breakdowns and delays.
• If you check everything, every time, you will be alert to little problems before they cost you time, money and violations. Your eyes will begin to catch things that have changed.

What about tires, what are you looking for?

• Check tire tread depth at the lowest spot … that’s where the DOT will check it
• Tires with cuts or exposed cord material are an out of service violation and must be replaced on the side of the road at a very high price
• You only need a penny to check the tread depth on your tires the distance between the edge of a penny and the top of Abraham Lincoln’s head is 2/32” the minimum tread depth for drive tires. Steer tires are 4/32”.
• Don’t forget the wheels… if they have dirt and oil in them, there is a seal leaking and it needs to be fixed. If you feel heat coming from the hub (careful not to touch, they can be very hot) you may have a bad bearing or it may be low on hub oil.

There are a lot of lights on a truck … if one or two are out is that ok?

• Be sure all lights work… If it’s on the truck it must work, even if it is a light you added that is not required.
• A single light out on the truck give the DOT a reason to pull you over and look at everything.
• Check your low beam and high beam headlights
• Check your lights every time you stop… they can burn out during the trip

Are drivers responsible for the lights on a chassis?

• Yes… you are responsible for the lights on the trailer or chassis, be sure they are working before you leave and check them whenever you stop. If they don’t work fix them.

What else should we look for on a trailer or chassis?

• Check the sliders on both trailer and chassis and the locking pins on chassis
• If you don’t bend over and look you don’t know if the slider’s pins are locked in the holes.

Is it possible wheels could come out from under the trailer?

• Yes the wheels can come all the way out from under the trailer or chassis…
• If you use zip ties to secure the locking pins on the 4 corners of the container you can be sure they stay locked and an added benefit is the DOT will see the zip tie and leave you alone.

What else should we check on the truck and trailer?

• The DOT is looking at brakes very closely…it is important that drivers check them on every trip.

Any tips on checking breaks?

• Check your brakes using your eyes, ears and nose.
• Using your eyes … are the brake pads at least 1/4” in thickness? Are the brake drums cracked or grease? Do the push rods travel more than 2 ½ inches? If the answer is yes to any of these questions you could be placed out of service and in for an expensive roadside repair.
• Use your ears… air up the brakes and listen for air leaks if you can hear it the DOT inspector will be able to hear it too.
• Use your nose… if you smell a burning smell it could be oil or grease dripping on your hot brake shoes; this could be a warning of a leaking wheel seal.

ABS Malfunction Indicator

• There are two Antilock Braking System malfunction indicator lights, one on the dash for the truck and one on the lower left rear corner of the trailer.

Should the lights be on or off?

• These lights should come on when you start your truck and go off when the truck starts moving. If they don’t go off you have a problem with the ABS system on your truck which needs to be fixed before you continue your trip. If the ABS light on the lower left rear corner of the trailer is on … it is like having a sign on the truck that says,”Pull me over I have violations”
• Remember the ABS lights should come on when you start your truck and go off when you start moving.
• Fire extinguisher
• Windshield wiper
• Horn
• Emergency triangles … you should have 3
• Is the floor neat and clean, so nothing that can get under your feet
• Is the dash clear of item that could slide off and distract you
• Is your truck clean… a clean truck is a happy truck and it is not inspected as often by the DOT
