The Kentucky CDL knowledge test is a computerized exam that tests your knowledge of commercial driving laws, safety protocols and Kentucky specific regulations. This test is required to get a Commercial Learner's Permit (CLP) which allows you to practice with commercial vehicles before taking the skills test. The test covers topics such as vehicle operation techniques, Kentucky traffic laws, federal safety regulations and emergency procedures. Kentucky's testing system ensures you have the knowledge to operate commercial vehicles safely on Kentucky roads and across state lines.

In Kentucky you'll need to take the CDL knowledge test if:

• You're applying for your first Commercial Learner's Permit
• You want to add new endorsements to your existing Kentucky CDL
• You need to upgrade your license class (such as from Class B to Class A)
• You must reinstate a Kentucky CDL that has been expired for more than one year
• You're transferring a CDL from another state and need additional endorsements

The Kentucky Transportation Cabinet requires all CDL applicants to take the general knowledge test and additional specialized tests based on the type of commercial driving you'll be doing.

Kentucky's CDL knowledge test is the foundation for safer roads throughout the Commonwealth. The test verifies that commercial drivers know how to handle large vehicles, proper loading techniques and emergency procedures specific to Kentucky's varied terrain – from the mountains of Eastern Kentucky to the flat farmland of Western Kentucky. Since commercial vehicle accidents can be devastating, this test is the first line of defense to ensure only qualified people are driving these vehicles on Kentucky roads.

Kentucky's CDL testing program meets Federal Motor Carrier Safety Administration standards while adding state specific elements for driving in the Commonwealth. This dual approach means Kentucky CDL holders meet national qualification standards and are prepared for the unique challenges of Kentucky's roads – from mountain driving in the east, urban congestion in Louisville and Lexington and rural highways. This standardization means your Kentucky CDL is valid for intrastate and interstate commerce (as long as you meet age and additional federal requirements).

Kentucky's CDL knowledge test has multiple separate exams depending on your license class and endorsement needs:

• General Knowledge: 50 multiple-choice questions
• Air Brakes: 25 multiple-choice questions
• Combination Vehicles: 20 multiple-choice questions
• Passenger Endorsement: 20 multiple-choice questions
• School Bus Endorsement: 20 multiple-choice questions
• Hazardous Materials Endorsement: 30 multiple-choice questions
• Tank Vehicles Endorsement: 20 multiple-choice questions
• Doubles/Triples Endorsement: 20 multiple-choice questions

Each test has 4 answer choices and thoroughly tests your knowledge of Kentucky commercial driving regulations and safety procedures.

Sample Question: During a pre-trip inspection what should you check on the fifth wheel? A) That the fifth wheel is secured with the jaws around the shank of the kingpin B) That the release arm is in the unlocked position C) That there is space between the upper and lower fifth wheel D) That the apron rests on top of the fifth wheel

Answer: A) That the fifth wheel is secured with the jaws around the shank of the kingpin

Kentucky requires an 80% correct answer rate on each section of the CDL knowledge test:

• General Knowledge: 40 out of 50 questions correct
• Air Brakes: 20 out of 25 questions correct
• Combination Vehicles: 16 out of 20 questions correct
• Passenger Endorsement: 16 out of 20 questions correct
• School Bus Endorsement: 16 out of 20 questions correct
• Hazardous Materials Endorsement: 24 out of 30 questions correct
• Tank Vehicles Endorsement: 16 out of 20 questions correct
• Doubles/Triples Endorsement: 16 out of 20 questions correct

Kentucky only offers the CDL knowledge test in English. This aligns with federal requirements that commercial drivers must have sufficient English proficiency to interpret highway signs, communicate with enforcement officers, complete shipping paperwork, and understand vehicle instructions. Kentucky testing officials cannot provide translations or interpreters during the examination. This English-only requirement applies to all CDL testing in Kentucky, with no exceptions.

No, Kentucky's CDL testing procedures prohibit all study aids, reference materials, and electronic devices during the examination. Testing monitors in Kentucky CDL testing facilities will require you to store all personal items before beginning your test, including:

• Mobile phones and all electronic devices
• Personal notes, flashcards, or study sheets
• Kentucky CDL manuals or handbooks
• Reference guides of any kind
• Calculators (except when explicitly permitted for specific calculations)

Using unauthorized materials during your Kentucky CDL test may result in automatic test failure and could impact your eligibility for future testing opportunities with the Kentucky Transportation Cabinet.

Kentucky's CDL knowledge test doesn't impose strict time constraints, but most applicants complete the general knowledge portion within 60-90 minutes. The specialized endorsement tests typically require 30-45 minutes each. Kentucky testing facilities allocate sufficient time for careful consideration of each question without unnecessary pressure. If you have documented learning disabilities or other qualifying conditions, the Kentucky Transportation Cabinet can provide appropriate accommodations with proper documentation submitted prior to your test date.

We recommend understanding the underlying concepts rather than memorizing specific practice test answers, as Kentucky's actual CDL test draws from an extensive question bank.

Kentucky offers CDL knowledge testing at Kentucky Transportation Cabinet (KYTC) Driver Licensing Regional Offices throughout the Commonwealth. These dedicated regional facilities have replaced county clerk offices for CDL services. Regional testing locations include Bowling Green, Elizabethtown, Lexington, Louisville, Paducah, Prestonsburg, Somerset and other strategic locations across Kentucky. Visit drive.ky.gov for a complete list of Kentucky's CDL testing locations.

Yes, Kentucky requires appointments for CDL knowledge testing. Schedule your test through:

• Kentucky's official online scheduling portal at drive.ky.gov
• Calling your nearest KYTC regional office directly
• Using Kentucky's Driver Licensing Division telephone scheduling system

While some Kentucky locations might occasionally accommodate walk-ins for CDL testing, appointment holders receive priority. The appointment system ensures testing availability and minimizes wait times at Kentucky's regional licensing offices.

No, Kentucky doesn't offer online CDL knowledge testing. Federal regulations and Kentucky state law require in-person testing at authorized KYTC Regional Offices to verify your identity, maintain test security and ensure testing integrity. This in-person requirement applies uniformly across Kentucky and all other states. Kentucky's in-person testing protocols help prevent impersonation and ensure that CDL recipients have personally demonstrated the required knowledge.

When taking your Kentucky CDL knowledge test, bring these required documents:

• Current Kentucky driver's license
• Social Security card or verification of your Social Security number
• Birth certificate, U.S. passport or permanent resident card
• Two proof of Kentucky residency documents (utility bills, tax records etc.)
• Valid DOT Medical Examiner's Certificate (Form MCSA-5876)
• Completed Kentucky CDL application form
• Payment method for applicable fees
• For hazardous materials testing: Additional identification for security screening

Kentucky requires original documents or certified copies—standard photocopies aren't accepted. Contact your regional KYTC office if you have questions about specific document requirements.

Arrive at the Kentucky testing center at least 15-20 minutes before your scheduled appointment to:

• Process your documentation
• Complete application procedures
• Pay testing fees
• Prepare for the testing environment

Late arrivals may need to reschedule according to Kentucky Transportation Cabinet policies. First-time Kentucky CDL applicants should consider arriving 30 minutes early to allow for additional paperwork processing. Factor in traffic conditions, especially at busy Kentucky locations like Louisville and Lexington.

After passing Kentucky's CDL knowledge tests, you'll receive a Commercial Learner's Permit (CLP) valid for 180 days with these Kentucky restrictions:

• 14-day waiting period before taking the skills test
• Must be accompanied by a licensed CDL holder in the passenger seat
• No passenger transport (except instructors, examiners, or other trainees)
• No hazardous materials transport
• Additional restrictions based on your testing and vehicle specifications

Your Kentucky CLP will display the endorsements you've successfully tested for, allowing practice with those specific vehicle types or functions.

Your Kentucky Commercial Learner's Permit allows you to practice driving commercial vehicles under specific conditions:

• You must be accompanied by a qualified Kentucky CDL holder at all times
• You can operate vehicles matching your permit's class and endorsements
• You can drive on all appropriate Kentucky roadways and interstate highways
• You can develop the skills necessary for your eventual skills test

Kentucky's CLP provides essential hands-on experience before your skills evaluation. Use this period to become thoroughly familiar with commercial vehicle operation under proper supervision.

KENTUCKY REQUIREMENT: Kentucky follows the federal mandate requiring CLP holders to wait a minimum of 14 days before taking their skills test. Use this time effectively to practice commercial vehicle operation within Kentucky's diverse driving environments.

In Kentucky, your CDL knowledge test scores are good for the entire 180-day CLP period. If your Kentucky CLP expires before you take your skills test, you'll need to retake all knowledge tests. Kentucky doesn't offer extensions on these testing requirements, so plan your skills testing within the six-month window to avoid re-taking the knowledge test. This will keep your knowledge current when you apply for your full Kentucky CDL.

If you don't pass a Kentucky CDL knowledge test:

• First failure: You can retest as early as the next business day
• Subsequent failures: Kentucky has a 7-day waiting period
• You only need to retake the tests you didn't pass
• Use our Kentucky practice tests to strengthen weak areas
• Review your incorrect answers to identify knowledge gaps
• Consider alternative study methods if specific topics are tough for you

Kentucky doesn't limit the number of testing attempts, but repeated failures may indicate you need more preparation.

Sample Question: In Kentucky, if you fail a CDL knowledge test section, when can you retest? A) Same day B) Next business day for first failure; 7 days for subsequent failures C) Must wait 30 days between attempts D) Must complete additional training before retesting

Answer: B) Next business day for first failure; 7 days for subsequent failures

After you've held your Kentucky CLP for the required 14-day minimum:

• Contact your Kentucky State Police testing location directly
• Ensure your Kentucky CLP is still valid and your medical certification is current
• Get an appropriate test vehicle for your desired license class
• Pay Kentucky's skills testing fee ($50)
• Choose from available testing appointments

Kentucky administers CDL skills testing through the Kentucky State Police at designated testing locations, separate from the knowledge testing sites. The three-part skills test includes pre-trip inspection, basic control maneuvers, and on-road testing on Kentucky roads.
