How many years of experience is required for a co-driver to accompany on the highway?

[LaKarter]

On the highway, a co-driver with more than three years of experience can accompany. Here are the relevant details: 1. Accompanying driver: When a driver operates a motor vehicle on the highway during the probationary period, they must be accompanied by a driver who holds a driver's license for the corresponding or higher vehicle class for more than three years. The accompanying driver should sit in the co-driver's seat to guide the probationary driver. 2. Probationary period: The probationary period for a driver is 12 months from the date of first obtaining the driver's license or adding a new vehicle class (i.e., 12 months from the "initial license date" on the main copy of the driver's license); if the probationary period is extended, it will be 24 months from the "initial license date."
