Probably Asked A,thousand Times.

I took my test today. I passed the pretrip but failed skills so I have to take skills and the road trip next time. Many students get confused at the school. The exam course is kind of funky. I got all hundreds when I took the skills tests on the range in every course but one so knowing how to do the skills is not the problem. Just a very funky course with the test boxes all lined up together and lines and cones everywhere. When I finished pretrip I was thrilled because I think in many ways it is the most difficult and because I've done so well with skills I started thinking ahead to the road and lost focus.

You are right as they must have a valid CDL in order to accompany the permit holder taking his test. When I took my test the tester who was also the owner of the atlas testing site. Never drove a truck a day in his life he said. Just wanted to help Kevin to calm Himself before his test

Yosemite Sam wrote in response to the CDL exams:

Just think of it as a demonstration rather than a test. U are demonstrating to the tester what is done while pre tripping doing ur backing and finally ur road test. The tester probably never drove a truck in his or her life. Everyone is nervous just try to take a deep breath and show the tester what u got.

Sam...the "tester" must hold a valid and active CDL, they are accompanying a CDL permit holder on public roads and highways. At least the ones I have met and know, they are all former truckers.
