A Pennsylvania CDL applicant points to a steering part and names it. What must the applicant also do during the vehicle inspection test?
Correct answer: Explain what condition or defects are being checked
Identifying a part alone is incomplete. The applicant must name it, point to or touch it as appropriate, and explain what is being inspected to judge whether it is safe.

During a backing exercise, the driver has safely stopped and secured the truck, then opens the door to judge its position. The driver stays seated. What does this count as?
Correct answer: A look, even though the driver remained seated
Opening the door or moving from the seated position counts as a look. Remaining inside the cab does not make that action uncounted, and opening the door while moving is unsafe.

How do the stated pull-up and outside-check allowances compare for Pennsylvania's two backing exercises?
Correct answer: Straight backing: one free pull-up and one exit; reverse offset: two and two
The written instructions allow one free pull-up and one safe exit for straight-line backing, and two free pull-ups and up to two safe exits for reverse-offset backing. The examiner explains these allowances; safety requirements still apply.
