        (8)         Despite subrule (2), a driver may approach and enter the roundabout from the marked lane next to the left lane as well as, or instead of, the left lane if—

            (a)         the driver's vehicle, together with any load or projection, is 7.5 metres long, or longer; and

            (b)         the vehicle displays a do not overtake turning vehicle sign; and

            (c)         any part of the vehicle is within 50 metres of the nearest point of the roundabout; and

            (d)         it is not practicable for the driver to leave the roundabout less than halfway around it from within the left lane; and

            (e)         the driver can safely occupy the next marked lane and can safely leave the roundabout less than halfway around it by occupying the next marked lane, or both lanes.

        (9)         Despite subrule (3), a driver may approach and enter the roundabout from the marked lane next to the right lane as well as, or instead of, the right lane if—

            (a)         the driver's vehicle, together with any load or projection, is 7.5 metres long, or longer; and

            (b)         the vehicle displays a do not overtake turning vehicle sign; and

"marked lane", for a driver, does not include a special purpose lane in which the driver is not permitted to drive.

"right lane" means—

            (a)         the marked lane nearest to the dividing line or median strip on the road; or

            (b)         if there is an obstruction (for example, a parked car or roadworks) in that marked lane—the marked lane nearest to that marked lane that is not obstructed.
