When a post-trip inspection reveals a problem or unusual situation, when should it be reported?
Correct answer: A – Immediately
A post-trip inspection should include a search for mechanical or operational problems, damage, vandalism, sleeping students, and articles left aboard. Any problem or special situation must be reported immediately to the supervisor or school authorities. Prompt reporting allows safety concerns to be evaluated before the bus returns to service.
