Kentucky CDL General Knowledge: Driver Fitness Test 2026

A rested, healthy driver is the cheapest safety device a fleet owns, which is why the Kentucky CDL driver fitness and hours of service test matters so much in 2026. The questions run through daily and weekly driving limits, required rest breaks, keeping an accurate log, and recognizing when illness, medication, or plain exhaustion means you should not be behind the wheel at all.

Hours-of-service math trips up a lot of candidates, so several items ask you to reason about when your clock resets and when you are out of legal hours. The Kentucky Commercial Driver License Manual spells these federal rules out, and reviewing that chapter first makes the numbers far less intimidating during practice.

Fitness and hours questions sit inside the broader 50-question general knowledge test tied to your Commercial Learner's Permit. Repeat this drill until log limits and self-assessment feel second nature, then push on to the remaining topic sets.
