School Bus CHP Practice Test 2026 - Free School Bus Certification Practice Questions and Study Guide

The statement that alcoholic beverages may be carried on a bus only when no pupils are aboard is deemed incorrect because regulations typically prohibit any presence of alcoholic beverages on school buses at all times, regardless of whether students are aboard or not. School bus regulations are designed to ensure the safety and well-being of students, and allowing any alcohol, even if students are not present, contradicts these safety protocols.

In contrast, the other statements align with established regulations. Smoking being permitted only when no pupils are aboard emphasizes the need to maintain a healthy environment for students. The prohibition of transporting hazardous materials on school buses is established to prevent any potential harm to students and drivers. Lastly, the requirement that the bus shall not move until doors are closed with passengers aboard is a critical safety rule to ensure all students are safely seated and secure before the bus begins to operate.
