I still think they should go through them and look to see if they have a valid CDL license and school. That they can read road signs. I just went through CDL school and I had to do all of that and even take a real drive test with a state driving inspector and he asked me not once but twice what the road signs were as I passed them on the highway road test. No one should be driving these trucks without knowing how to read a road sign and speak english.
