15. Why should the steps of a pre-trip inspection be done in the same order each time?

Distractions that can affect safe driving can be classified as physical (such as reaching for an object), mental (such as talking with passenger), or both (such as talking on a hand-held phone).

When checking the tires as part of a pre-trip inspection, make sure the tires have sufficient tread. There should be at least 4/32 of an inch of tread in every major groove of the front tires, and at least 2/32 of an inch of tread depth on the other tires. Tires should not be mismatched in size and radial and bias-ply tires should not be used together.
18. An after-trip inspection should be done:
Explanation
You should always complete an after-trip inspection of your vehicle at the end of a trip, day, or tour of duty. Complete a vehicle inspection report, if required.

Explanation
Fully-loaded rigs are more vulnerable to rolling over than empty rigs because the weight of the cargo gives the vehicles higher centers of gravity.

Explanation
The trailer hand valve (also referred to as the "trolley valve" or "Johnson bar") works the trailer brakes and should be used only when testing them. Using the trailer hand valve while driving could result in a skid.
