I get a bit nervous when a special tax is levied on one sector, in this case trucking; I understand the rationale that heavy trucks do more damage, but there is always the risk of predatory taxation levied against a politically vulnerable minority. Maybe we should tax all vehicles based on weight, and let the soccer moms in their SUV's pay their share.
Whether Georgia spends its highway dollars wisely or poorly is a separate question. Nationally there is clearly an infrastructure backlog. People bicker on how to pay for improved infrastructure, but the need is there.
The implication is that it will pay for roads, but it is a "transportation" tax not a road tax. Doubtless large fractions of it will be squandered on things like transit, light rail (always a politician's favorite), bike paths, etc. make no mistake about it this is plundering of the GA taxpayers pure and simple. What they should have done is cut spending elsewhere to pay for this, but easier to stick it in the taxpayers' collective backsides than risk offending any of the mouthy special interest groups that grow fat on taxpayer loot.
