A 13-metre rigid bus without a trailer travels on a dual carriageway outside a built-up area with three ordinary lanes in its direction. With no snow, sign or instruction preventing it, may it use the leftmost lane?

Correct answer

Yes, when traffic or road conditions make it advisable and it does not hinder the progress of another vehicle.

Yes, when traffic or road conditions make it advisable and without impeding a following vehicle. Normally use the right-hand lane. Article 31.2 limits lorries or vans over 3,500 kg, special vehicles not required to use the shoulder and combinations over seven metres to the two rightmost lanes. A rigid bus without a trailer is not a combination merely because it is 13 metres long. Observe specific restrictions and the special lane rule for snow.
