Great decision. The original rules were leftist anti-trucks efforts and would have crippled the movement of goods (hint, hint, like today’s Marxist Biden rules and California port rules).
You can see that Marxist Obama tried to cripple the US economy. Now BloJo and his Obama communist advisors are following his program to the “T”.
I worked in environmental cleanup affairs for almost 30 years and Obama/Biden put forth the most economically crippling and stupid proposed rules and actual rules in modern US history.
About time that they were stopped from their “total economy control” Marxist programs.
It is a safety issue too. Brakes run a lot hotter going down steep grades with the skirts reducing much needed extra air flow through the brake drums.
