A **passenger car with a trailer** is allowed to drive on an **additional lane**. This is because additional lanes are created on roads with two-way traffic to facilitate the flow of traffic when there are many vehicles. These lanes are marked with beacon signals and allow vehicles, including passenger cars with trailers, to drive on them under certain safety conditions, such as maintaining a speed between 60 and 80 km/h and using low beam headlights.


There are no specific restrictions for passenger cars with trailers in these additional lanes, as long as the traffic rules established for these lanes are followed.
