En un estrechamiento sin señal de prioridad se encuentran por un lado un turismo que arrastra un remolque y por el otro un autobús, sin que se sepa quien entró primero. ¿Cuál de ellos tendrá prioridad?

On stretches of road so narrow that it is impossible or very difficult for two vehicles travelling in opposite directions to pass at the same time, and where there are no specific signs, the vehicle that entered first has right of way. If there is doubt, the vehicle that finds it harder to manoeuvre has right of way, in this order of priority: 1. Special vehicles and special transport exceeding the masses or dimensions set in vehicle regulations. 2. Combinations of vehicles, except those in point 4. 3. Animal-drawn vehicles. 4. Cars towing trailers with a maximum authorised mass of up to 750 kg, and motor caravans. 5. Vehicles used for public passenger transport. 6. Lorries, tractor units and vans. 7. Cars and car-derived vehicles. 8. Special vehicles not exceeding the masses or dimensions set in vehicle regulations, quadricycles and light quadricycles. 9. Three-wheeled vehicles, motorcycles with sidecar and three-wheeled mopeds. 10. Motorcycles, two-wheeled mopeds and bicycles. So in the case in the question, the car towing a trailer has right of way.
