Not according to the fmcsa website
Sorry, but I call BS. Show me where it says that having a CDL cuts your BAC in half while not operating a commercial motor vehicle. I can't find anywhere that shows that a CDL causes you to get more points for traffic offenses either.
I don't drive for a living, but I hold a class A CDL. It doesn't affect my life or driving habits any, except that I get a physical for free every other year, and I am subject to random drug tests through work. I dont have to worry when I'm pulling a gooseneck trailer behind my truck about getting a fine either. I have heard the same excuses from others about why they won't get their license, and instead, choose to drive illegally. I think that's pretty dumb.
