laws that same money
California started the trend, with a law about truck fuel use tied to trailer aerodynamic drag. Truckers bitched up a storm. Guess what. They save 6 - 7.5% on fuel use, combined with side skirts 12%, with low rolling resistant tires even more. The ROI (return on investment), depends on miles and speeds but in most cases 1 year. Truckers everywhere are adding them. That's lower freight costs for consumers, less pollution, less pressure on fuel prices, 12% fewer hours parked at a fuel pump. Damn the government and their anti-business laws.
In Europe some trucks now have flat hubcaps of cheap material, they save 1%, and also claim 1 year ROI, I have seen a few of these here. Bonus for other drivers, trailer tails reduce the mist cloud behind the truck in wet conditions
