Cross the railway crossing at a speed of more than 30 km / h
Cross the railway crossing at a speed of less than 30 km / h
Driving at a speed of 8 km / h at low speeds with tractors attached to the rails without the permission of the head of the railway section✓Respuesta correcta
Explicación
Machines whose speed is below 8 km/h, and tractor-drawn drag sleds, may cross only with permission from the head of the railway section because they can occupy the track for unusually long. Those conditions, not whether an ordinary vehicle crosses above or below 30 km/h, trigger the permission requirement.
