* GVWR (Gross Vehicle Weight Rating): A Class B CDL is required for vehicles with a GVWR of 26,001 lbs or less. While a 16,000 lb trolley might seem light, the weight of the trolley itself plus any cargo or passengers it carries could easily exceed that limit.
* Air Brakes: A Class B CDL is also required for vehicles with air brakes. This is a safety measure to ensure drivers are properly trained to operate vehicles with this type of braking system.
Important Note: Specific regulations vary by state. It's always best to consult with your state's Department of Motor Vehicles for the most accurate information.
