Which of the following actions is NOT explicitly stated in the text as something that vehicle owners or safety driving managers must not order drivers to do or tolerate?

Answer: C: Overloading violations

Explanation

The text in "2 (5)" lists items (a) through (f), including "unlicensed driving," "maximum speed violations," and "drunk driving or alcohol-impaired driving." "Overloading violations" is described in item (e) as "driving a vehicle in violation of loading restrictions," using different wording. Since the question asks what is "not explicitly stated," all are mentioned, but "overloading violations" is phrased as "violations of loading restrictions" rather than the exact term used in the option.
