Incorrect, FEDERAL is any vehicle with a towed unit that is over 10K that crosses state lines OR a 26,001 GVW (license, rated, actual) unit with or w/o towed unit.
Laws very by STATE that may say the total GVW of both needs to be over 26K, I know MN is this way, but Federal is anything in commerce with a towed unit over 10K crossing state lines.
Sorry Bud you are wrong here.
.Question 2: Is a driver of a combination vehicle with a GCWR of less than 26,001 pounds required to obtain a CDL even if the trailer GVWR is more than 10,000 pounds?
Guidance: No, because the GCWR is less than 26,001 pounds
