Kentucky General Knowledge Test

About the Kentucky General Knowledge Test

Driving a big rig in Kentucky means you'll tackle everything from the steep grades of I-64 through the Appalachian Mountains to the heavy traffic around Louisville's I-65/I-264 interchange. Our winters bring ice and snow, especially in the eastern part of the state. Spring storms can spawn tornadoes without warning. You need to know your stuff before that DMV test.

Kentucky's roads carry more than just freight. You'll share the road with horse trailers going to Keeneland, coal trucks rolling out of Pike County, and farm equipment on rural highways. The General Knowledge test covers the rules you'll use every day: vehicle inspections, proper shifting on hills, and how to handle emergencies.

Our practice test uses questions pulled straight from the Kentucky CDL manual. We don't add fluff. Each question teaches you something you'll need. We explain every answer, so you learn why the right choice works. No guesswork.

Pass the Kentucky General Knowledge test on your first try. You'll save time and money. Study with us, and you'll walk into that DMV office ready.

What This Test Covers

• Vehicle Inspection: Kentucky's safety inspections happen before every trip; you'll learn the 7-step method to avoid failures.
• Basic Control: Mastering your mirrors and steering matters for navigating Lexington's construction zones.
• Shifting Gears: Kentucky's hills require proper gear selection; don't grind gears on I-75's slopes.
• Air Brakes: Cold Kentucky winters mean air line freeze-ups; understand air brake systems to stay safe.
• Emergency Procedures: Tornadoes and flash floods hit Kentucky; know how to react when weather turns bad.
• Hazard Perception: Watch for deer on country roads and sudden stops on I-264; this section sharpens your awareness.

Study Tips

Start with the Kentucky Commercial Driver's License Manual — get it free online or at any DMV. Focus on the sections we cover in this practice test. Don't just memorize answers; understand why each rule exists. Kentucky's roads throw curveballs, and you need to think on your feet.

Schedule your knowledge test appointment early — Louisville and Lexington offices fill up fast. Use our practice test to find your weak spots. Then review those sections in the manual. Take the test multiple times until you score 90% or higher. That margin gives you room for test-day nerves.

On test day, bring your Social Security card, proof of residency, and a medical examiner's certificate if you need one. Arrive early. Don't rush through the questions. You have 60 minutes for 50 questions — that's plenty of time. Read each question twice before answering.

You must pass the vision screening before taking the test. Bring your glasses or contacts if you need them. If you fail the knowledge test, you can retake it the next business day. There's no limit on retakes, but each try costs $12.
