[LaMatthew]

The minimum speed limit for driving on elevated roads is 60 kilometers per hour. Procedure for handling breakdowns: When a motor vehicle breaks down on the highway, the relevant provisions of Article 52 of this law shall apply; however, warning signs should be placed at least 150 meters away from the direction of oncoming traffic, and passengers should quickly move to the right shoulder or emergency lane and promptly call the police. Precautions: If a motor vehicle breaks down or is involved in a traffic accident on the highway and cannot be driven normally, it should be towed or pulled by a rescue vehicle or a wrecker. No unit or individual may intercept or inspect vehicles on the highway, except for public security police officers performing urgent official duties in accordance with the law.
