Common Questions (FAQ)

Do I need a CDL to drive a delivery van?

Only if the vehicles Gross Vehicle Weight Rating (GVWR) exceeds 26,001lb or if you are transporting hazardous materials that require a CDL endorsement. Most lightduty delivery vans fall under ClassC and do not need a CDL.

What is the tank vehicle endorsement (N) for?

The N endorsement authorizes drivers to operate vehicles designed to transport liquids or gases in bulk. It requires a separate written test and a practical demonstration of safe tankvehicle operations.

How often must my fleet perform a vehicle inspection?

At a minimum, each commercial vehicle must receive a thorough inspection every 12 months, plus any additional checks mandated by the FMCSA (e.g., pretrip, posttrip, and random roadside inspections). Vehicles carrying hazardous materials often have more frequent inspection schedules.

Can I use a paper logbook instead of an ELD?

Paper logbooks are permitted only for drivers who are exempt from the ELD rule (e.g., drivers who operate within a 100airmile radius and return to their work reporting location each day). Otherwise, an ELD is mandatory.
