Kansas CDL Practice Test 2025

Kansas CDLs are issued by the Kansas Department of Revenue (DOR), Division of Vehicles. Kansas does not have a DMV. CDL applicants must visit a DOR Division of Vehicles office to complete knowledge tests, submit a current DOT medical certificate, and complete the CDL skills test with an approved examiner. DOR offices are located in most Kansas counties. When searching for a CDL testing location in Kansas, search for 'Kansas DOR Division of Vehicles' rather than 'Kansas DMV.'

All Kansas CDL applicants must pass the General Knowledge test. Additional tests are required based on the vehicle class and endorsements: Combination Vehicles (Class A), Air Brakes (if the vehicle has air brakes), Passenger Transport, Hazardous Materials (plus TSA security threat assessment), Tank Vehicles, Doubles/Triples, and School Bus. Each test requires a minimum score of 80%. Kansas CDL applicants should also understand state-specific operational requirements including I-70 crosswind advisories, Kansas Turnpike toll procedures, and KDOT seasonal overweight permit processes.

The FMCSA BAC limit of 0.04% applies to CDL drivers operating a CMV in Kansas. Kansas uses DUI terminology. Kansas also prohibits CDL drivers from consuming alcohol within 4 hours before operating a CMV. A CDL driver who tests at 0.04% BAC or above is placed out of service and faces CDL disqualification. The standard Kansas DUI limit of 0.08% applies to CDL holders driving personal (non-CMV) vehicles, and the 0.02% limit applies to CDL holders under 21.

The Kansas Turnpike Authority (KTA) operates I-335 (the main Kansas Turnpike) and portions of I-70 near Wichita. CDL vehicles on KTA routes pay commercial vehicle toll rates, which are higher than passenger car rates and are based on vehicle axle count and weight class. Drivers can pay with exact change cash at toll plazas or use a K-TAG electronic transponder for automated billing. Commercial fleet operators often use K-TAG accounts for CDL vehicles. Bypassing a toll plaza is a violation. CDL drivers should verify the toll amounts for their specific vehicle configuration before traveling KTA routes.

Kansas I-70 presents multiple operational hazards for CDL drivers. Crosswinds of 30–50 mph can push high-profile CMVs off the road — KDOT monitors conditions and issues crosswind advisories and restrictions for specific vehicle types. Dust storms from agricultural fields have caused multi-vehicle pileups on I-70. Winter ice and blizzard conditions can trigger I-70 closures. Variable speed limit zones near Wichita (I-70/I-135 interchange) require CDL driver attention. CDL drivers should monitor KDOT's 511 road conditions system throughout any I-70 transit in Kansas and be prepared to stop and wait out dangerous conditions rather than proceeding through them.

A Class A CDL allows you to operate any combination of vehicles with a Gross Vehicle Weight Rating (GVWR) of 26,001 lbs or more, provided the towed unit exceeds 10,000 lbs — this includes tractor-trailers and double/triple trailer rigs. A Class B CDL covers single vehicles with a GVWR of 26,001 lbs or more, or any such vehicle towing a unit not exceeding 10,000 lbs — this includes straight trucks and large buses. A Class C CDL is required for vehicles designed to carry 16 or more passengers (including the driver) or for vehicles transporting hazardous materials that require placarding, when those vehicles do not qualify for Class A or B.

CDL fees vary by state and by the class and endorsements you obtain. Most states charge separate fees for the CDL knowledge test ($10–$30 per attempt), the CDL skills test ($50–$150), and the CDL license itself ($50–$100). Additional fees apply for each endorsement (HazMat, Tanker, Passenger, etc.). The HazMat endorsement also requires a TSA security threat assessment fee of approximately $86. Check your Kansas DMV website for current fee schedules.

Federal regulations (49 CFR 383.133) require that CDL applicants be able to read and speak the English language sufficiently to understand highway traffic signs and signals and to respond to official inquiries. Many states offer CDL knowledge tests in Spanish and other languages for non-commercial knowledge questions, but the actual CDL test must be taken in a language that allows the driver to meet the English proficiency requirement. Check with the Kansas DMV for available language options.

In most states, a CDL is valid for 4–8 years (commonly 4–5 years). To renew your Kansas CDL, you typically need to visit a DMV office, pass a vision test, pay the renewal fee, and update your medical certification (DOT physical). If you hold a HazMat endorsement, your TSA background check must also be current. CDLs cannot generally be renewed online due to federal requirements for in-person verification of medical certification.

If you fail the CDL General Knowledge test in Kansas, you are typically required to wait a specified period (commonly 1–7 days) before retaking it. Most states allow 2–3 attempts before requiring additional waiting periods or study requirements. There is usually a retest fee for each attempt. Focus on the areas you missed — most states provide a score sheet showing which topic areas you need to review.
