4.1.4Mitigating measures – cross section#

The primary risks associated with narrower lane widths is reduced manoeuvrability space for larger vehicles and the increased potential for side swipe collisions. The element considered key to successfully implementing narrow lanes would be the restriction of wider vehicles to only use those lanes maintained at the lane widths specified in the Queensland MUTCD Part 3, or wider where required for specific projects.

QLD Road Rules Regulation 104 (reproduced below – in part) appears to allow the use of a “No Trucks” sign to apply to only some lanes on a road as per subsection (5). The relevant parts of the clause are highlighted.
