If you want to reduce road damage then slow down the trucks to something less than 80 km/h.
Why, when the road is designed for 100km/h operations?
As a rail fan, I get despondent when government cuts maintenance on rail lines and the easiest solution is to cut speed limits, when they should invest and maintain the asset (the rail line) at the design level. they do this over many years. Every state has seen this.
Roads are no different.
I live in a region, why should I put up with a government underspending on their responsibility to maintain assets, that tax payers paid for in the first place with. This applies to all assets.
If the government wants to change service levels, then they should have the gonads to go to the community and have the discussion on why they can't and how they will use the funding instead. Instead, they will erode maintenance funding over time, to fund new
assets that they have no thought how they will be funded into the future to operate, as they won't be around in 3 years time. So over time the existing assets service levels drop by stealth, so they can have ribbon cutting exercises for the next white elephant.
Good on the VFF, on calling this out. Sorry linking this to speed kills, is dog whistling. Read their statement as posted. They are not saying everyone has a right to speed. They are saying do not let roads deteriorate. Fair call.
