These are independent truckers. The large trucking companies are not part of the protest. Many of their truckers are in the protest but not with their trucks.
And they should not be in those large company's trucks if the independents strike.
Or any other driver for that matter.
Just because they work for a company does not mean they are not subject to the mandates.
A trucking company can not remain operational with only a small fraction of their drivers.
.
Leaving the large trucking companies with abundant trucks and few drivers.
Same net effect.
