How this list was compiled: Own questions, written from the Revised Statutes of Missouri, chapters 301, 302, 304, 307 and 387, read section by section on the Revisor of Statutes site, https://revisor.mo.gov/main/Home.aspx, on 2026-10-04, and from two rules of the Department of Revenue in 12 CSR 10-24 (10-24.060 on written examinations and 10-24.200 on license classes), read on 2026-10-04 in the Secretary of State's current copy of the chapter, https://www.sos.mo.gov/cmsimages/adrules/csr/current/12csr/12c10-24.pdf, whose pages carry their own dates: 10-24.060 is on a page dated 7/31/23, and sections (4) and (5) of 10-24.200 are on a page dated 8/31/25. The Missouri Driver Guide (Revised August 2026), https://dor.mo.gov/driver-license/guide/, read 2026-10-04, says the Class E written exam has questions based on the complete guide, mainly Chapter 15 (Commercial Vehicles). Nothing here was taken from the guide, so this bank does not cover everything in it: the guide's driving methods, off-tracking, following-time advice, emergency equipment list and permit phone numbers are not here, and neither are the rules of the road that the Missouri permit bank on this site asks. Exam facts: 12 CSR 10-24.060(1)(C) asks a Class E applicant for 20 of 25 questions on commercial motor vehicle laws, in addition to 20 of 25 as for a Class F license. Licence: Own work. Statutes and rules of the State of Missouri are cited as the source of each fact and are not copied as questions.
How it works
This unofficial study guide is a practice test for Missouri's Class E for-hire license. The real test is based on the Missouri Driver Guide; these 93 questions come from state law and do not cover it all.
Read the full guide
Who needs a Class E license
Class E covers a driver paid in wages, salary, commission or fare to carry persons or property, and an employee who regularly drives another person's commercial motor vehicle (RSMo 302.015). The minimum age is 18 (302.060). Taxi, ride-hail and prepared food delivery drivers in vehicles of 12,000 pounds or less need only Class F (387.438).
What the Class E written test asks
The Missouri State Highway Patrol gives it. The state rule asks for 20 of 25 questions on commercial motor vehicle laws, plus 20 of 25 as for Class F, a part waived for a Class F holder who gives the examiner a copy of the test paper (12 CSR 10-24.060). Exam mode draws 25 and marks a pass at 80 percent.
Start with Weight limits in the Start from menu: 20,000 pounds on one axle, 34,000 on a tandem axle (RSMo 304.180).
A vehicle carrying passengers for hire stops 15 to 50 feet from the nearest rail at a railroad grade crossing (RSMo 304.030).
Commercial motor vehicles licensed for more than 18,000 pounds stop at official weigh stations (RSMo 304.235).
Questions and answers
Are these the questions on the real Missouri Class E test?
No. The Driver Guide says the Class E written exam is based on the complete guide, mainly its commercial vehicles chapter. This bank copies nothing from it. Each question comes from the Revised Statutes of Missouri or a state rule, so read the guide too.
Is Class E the Missouri chauffeur's license?
Missouri's class rule has no chauffeur's license today. The license for paid driving below commercial driver's license size is Class E, the for-hire license (12 CSR 10-24.200). An older statute still mentions drivers licensed as chauffeurs in 1988 (RSMo 307.400).
How many questions are on the Missouri Class E test?
The state rule asks a Class E applicant for 20 correct out of 25 questions on commercial motor vehicle laws, in addition to 20 out of 25 as for a Class F license (12 CSR 10-24.060). The Driver Guide prints no count for Class E.
Do taxi and food delivery drivers need a Class E license in Missouri?
Not in a vehicle with a gross vehicle weight of 12,000 pounds or less. RSMo 387.438 says the state may not require more than a Class F license of a taxicab driver, a transportation network company driver or a prepared food delivery driver.
