How long after getting a C1 driver's license can you drive on the highway?

[DelJace]

A C1 driver's license holder can drive alone on the highway after one year of obtaining the license. Conditions for driving on the highway: If a driver operates a motor vehicle on the highway during the probationary period, they must be accompanied by a driver who has held a driver's license for the same or a higher vehicle category for more than three years. The accompanying driver should sit in the front passenger seat and provide guidance to the probationary driver. Failure to be accompanied by a qualified driver will result in a fine. Legal basis: Article 75 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses': A driver operating a motor vehicle on the highway during the probationary period must be accompanied by a driver who has held a driver's license for the same or a higher vehicle category for more than three years. However, drivers of small automatic transmission vehicles specially designed for the disabled can be accompanied by a driver who holds a driver's license for small automatic transmission passenger vehicles or higher. During the probationary period after adding a new vehicle category, the above restrictions do not apply when driving the original vehicle category.
