COMPLETE PRACTICE EXAM
Question 1 of 150
You are operating a powered industrial truck (PIT) in a busy mail processing
,facility. As you approach a blind corner, you sound your horn but do not hear a
response. What is the safest action to take?

B. Stop completely, sound the horn again, and then proceed slowly.
C. Proceed at a reduced speed, keeping your foot over the brake.
D. Rely on the mirror at the corner to check for oncoming traffic.
Correct Answer: B
Explanation: The safest practice at a blind corner is to stop, sound the horn,
and proceed only when you are confident the path is clear. Relying solely on
mirrors or simply slowing down (A, C) is insufficient, and maintaining speed (A) is
dangerous. A complete stop ensures maximum visibility and reaction time.

from it. What is your FIRST priority?
A. Attempt to identify the substance using a field test kit.
B. Carefully repackage the damaged item to stop the leak.

D. Move the package to a designated hazardous materials area.
Correct Answer: C
Explanation: Your primary duty is personal and public safety. The first step is
to secure the area by clearing personnel and isolating the suspicious item.
Notifying a supervisor or security (C) triggers the proper emergency response. Do
not handle or test the substance (A, B, D), as this can expose you to potential

be professionally repaired. Performing repairs yourself (D) is a violation of safety
policy, and taping the cord (A) is a temporary, unsafe fix. Ignoring it (C) is a serious
safety violation.
