Really? So how come trucks were banned from using the outside lane on
motorways with three or more lanes?

What makes you think that regulation only applies to motorways?

As it happened, it did only apply on motorways.

It didn't (and AFAIK still doesn't) apply on (the limited number of)
six-lane quasi-motorways such as the A1 at Hatfield (now part of A1(M)
anyway), the A2 at Dartford, the A3 at Kingston, the A12 between M25 and
Colchester or the A46 Stratford - Coventry.
