CDL restriction codes are used by the California Department of Motor Vehicles (DMV) to indicate certain limitations or requirements for Class A CDL holders. These codes are important because they help make sure the safety and security of drivers, passengers, and other road users. Some common California CDL restriction codes include restriction code 50, which requires the driver to wear corrective lenses while driving, and restriction code 46, which restricts the driver to operating a vehicle with automatic transmission. Other CDL restriction codes may indicate the need for a hearing aid or for a driver to operate a commercial vehicle only within a certain geographic area. It is important for Class A CDL holders to be familiar with the California DMV restriction code list to ensure compliance with all relevant requirements.
