Oregon CDL Classes Explained

Which Oregon CDL class you need depends on vehicle weight, what it tows, and the type of operation, not just the truck size. The three classes are set by federal rule (49 CFR 383.91) and are the same in every state, so a Oregon CDL is valid nationwide. Oregon Driver and Motor Vehicle Services issues the license and runs the knowledge and skills tests. Oregon's port activity and timber industry make it a key Pacific Northwest freight origin and destination.
