CDL PRE-TRIP VEHICLE INSPECTION
MEMORY AID
You may use this list of vehicle components during the test to help remember components you must inspect as
described in the Oregon Commercial Driver Manual. You need only inspect those components with which your vehicle
is equipped.
As much as possible, you should inspect the components on your vehicle in the order they are listed below. This will help
you conduct a methodical inspection without missing required components.
When visible or accessible, you must point at or touch the component you are inspecting. If your vehicle has the
component but it is not visible or accessible, describe its location. Explain to the examiner how you are or would inspect
the component. Specifically describe conditions that would lead you to believe an item or component is illegal or unsafe. If
your vehicle does not have listed components, skip them and go to the next component/area.
The pre-trip inspection tests your familiarity with your vehicle and your ability to identify unsafe or illegal vehicle
components. It is not representative of the complete inspection that you would perform daily.
