DUmmie Tobin must live in a blue state, because I've had a CDL since 1984, including the required bi-annual physicals (the last one last year), and have never heard of such.
Outside of a basic vision test, color blindness test, and the standard height, weight, BP, etc., I have NEVER had to do anything more strenuous than "turn your head and cough" for any of them.
Hell, I passed one of them with a fever of 100.4 (bad case of bronchitis).
