CDL Practice Question #425

A bus driver may carry, in the baggage compartment, certain hazardous materials in small quantities except:

Class 1 explosives (other than small arms), Division 6.1 PIH, Class 7 radioactives above limited quantities, and tear gas
Letters and parcels
Personal luggage
Driver's tools

Correct. Strict prohibitions for buses include Class 1 explosives (other than small-arms ammunition), Division 6.1 PIH, most Class 7 radioactives, and tear gas.

Why this question matters

This question is one of 58 in our Passenger bank. The reasoning above comes directly from the AAMVA CDL Manual, the source document used by every U.S. state DMV. Memorizing the underlying rule — not just the letter answer — is what separates passing on the first attempt from a return trip and another fee.
