Driver Fitness, Fatigue & Legal Compliance
8 free questions, part of the General Knowledge CDL practice test
Driver fitness and legal compliance cover the rules that can get your CDL disqualified, like a 0.04% BAC while driving a CMV or two serious traffic violations in three years, plus the fatigue facts every driver needs to know. NHTSA research cited in the CDL manual puts drowsy-driving crashes at around 100,000 a year, and sleep, not caffeine, is the only real fix.

What BAC gets your CDL disqualified?
0.04 percent or higher while operating a commercial motor vehicle. That's half the limit used for non-commercial drivers in most states.
How many days do you have to report a traffic conviction to your employer?
30 days, and that includes convictions in your personal vehicle, not just while driving commercially.
What's the only effective way to fight driver fatigue?
Sleep. If you have to stop, a 15 to 20 minute nap is recommended. Caffeine only delays fatigue, it doesn't prevent it.
