"H" plates on trucks.
I thought that rule was brought in as "special" exemption to allow longer/heavier trucks to use certain roads. Yesterday I got stuck behind a convoy of 3 milk tankers on SH1, all with "H" plates. What was sold to the public as a needed exception in some special cases seems to have become the norm.
OOI why is the fact that they have H plates on an annoyance?
Bigger heavier trucks stuff the road surface much faster, longer trucks are harder to pass, but there should be some kind of compensation to the poor motorist by way of fewer large trucks than more small ones, but it doesn't seem to have worked out that way either.
Your bigger heavier H trucks have additional wheels, usually an extra axle. So no extra pavement loading. Bridges etc. have been strengthened to cope where required. If it wasn't three H tankers it would have been four (probably overweight) tankers doing damage to the road. I know what I'd choose.
Yeah - looking at some data from a letter from AA to NZTA, compliance for axle loading according to them was only 82%.
I'm just not sure about the logic of it WRT axle loadings - instead of 3 "H" plated trucks - why not have them 150 tonnes with 27 axles? Then there'd only be one to pass / only a third of the number of large trucks on the road.
