This commercial driver study guide covers relevant Federal Motor Carrier Safety Administration (FMCSA) Entry-Level Driver Training (ELDT) concepts and Ohio commercial driver knowledge topics. Review the regulations, procedures, and safety checklists below as part of your CDL and commercial learner permit (CLP) preparation.
Knowledge testing
Ohio requires at least 80 percent on General Knowledge and each required endorsement or equipment module. The official rule specifies 50 General Knowledge questions, 25 air-brake questions, 30 HazMat questions, and 20 for each listed combination or endorsement module.
Retesting
Ohio requires a two-day wait after failure of any skills-test segment. Knowledge-test retesting follows the current exam-station process; the live BMV instructions control scheduling and transaction limits.
Skills sequence
The skills test is completed in order: Vehicle Inspection, Basic Control Skills, then On-Road Driving. Failure ends that test attempt before the next segment; passed segment results remain usable only within the initial CLP issuance and all segments restart after CLP renewal.
Skills time and fees
At a state-owned site, Vehicle Inspection has a 30-minute limit and costs $10, Basic Control Skills has a 40-minute limit and costs $10, and the road test costs $30. Third-party fees vary. Ohio administers the CDL testing process in English.
Exam focus
Apply the rule to the exact Ohio vehicle, credential, date, trip, test stage, and operating facts in the question. Current Ohio BMV pages and Ohio law control when an older manual sentence conflicts with a newer official requirement.
Commercial Driver License Exam Readiness: Achieving a passing grade of 80% or higher on state DMV commercial driver knowledge exams requires mastery of federal vehicle inspection procedures, gross vehicle weight ratings (GVWR / GCWR), braking mechanics, and road safety regulations.
