In some states there are commercial speed limits which limit commercial vehicles to go much slower than passenger cars.
This is an unsafe practice as these passenger cars will do all it takes to pass any of these commercial vehicles; which at times may involve passing in heavy traffic areas which may result in a accident.
The commercial vehicles are driven by professionals whom have had many miles and much more training than passenger vehicle drivers.
Let's do our part and get these speed limits and commercial vehicle speed limits at the same speed by either raising or lowering the main speed limit on US Highways and Interstates across America.
