At a narrowing without priority signs or controlling instructions, no steep gradient and doubt about who entered first, an unaccompanied tractor unit and an ordinary lorry meet. If one must reverse, what criterion first decides priority between them?

Correct answer

Priority will go to whichever would have to reverse the greater distance.

Both are in the same Article 62 group: lorries, tractor units and vans. Priority goes to the vehicle that would have to reverse farther. With equal reversing distance, greater width, length or MAM is considered under the legal rule. A tractor unit with a semi-trailer would be a combination in a different class. Special vehicles do not all have priority over lorries; their category and conditions matter.
