Licence classes, testing and medical rules: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

The class licence system (fold-out) and Basic licensing requirements (pp. 3–4)

Class 1: semi-trailer trucks, plus everything in Classes 2–5; minimum age 18.
Class 2: buses seating over 24 passengers and school buses seating over 36, while carrying passengers; includes Classes 3–5.
Class 3: trucks with more than two axles; combinations with such a truck (not semi-trailers); a two-axle truck, or a Class 5 vehicle other than a truck, towing a unit registered over 4,540 kg; includes Classes 4 and 5.
Class 4: ambulances and other emergency vehicles, buses seating 10 to 24 and school buses seating 10 to 36 while carrying passengers; includes Class 5. Some municipalities require Class 4 for vehicles for hire.
A bus is any vehicle designed to carry 11 or more people including the driver that is not used only for personal transportation.
Authorized Instruction in Classes 2–4 needs at least a Class 5I or 5A licence; Class 1 needs at least a Class 5F (Full) licence. Road tests for Classes 1–4 need a Class 5F licence.
The supervising driver must have held a full Class 5 for at least three years, two of them in the class being learned, sit nearest the driver, have under .05 blood alcohol and pass any drug screening.
Class 1 applicants must show they completed an approved MELT course before booking the road test; practice hours as a 1A learner do not count toward MELT.
You must be tested for a class if you were never licensed in it, have not held a Manitoba licence in the past four years, or hold a non-exchangeable licence.

Test appointments and key points (p. 5)

Tests are by appointment through an Autopac agent and can be booked up to eight weeks ahead; weekdays, with Saturday appointments in Winnipeg.
Fees change: the manual lists a $10 knowledge test, but MPI's testing page (checked October 2026) lists $12 per knowledge test and road tests of $50 (Class 1, 2 or 3), $40 (Class 4) and $35 (air brake practical).
Knowledge tests for Class 1 and air brake are offered in English, French or Punjabi; Class 2, 3, 4 and school bus tests in English and French.
Knowledge tests have a 30-minute limit, are not open book, and phones and electronic devices are not allowed.
Only one knowledge or road test of the same class per day; Class 1–4, air brake and school bus knowledge tests can be repeated the next working day.

Ch. 1 Class 1 to Class 4 requirements (pp. 8–10)

A Medical Examination Report is mandatory for Classes 1–4; you may write the knowledge test before it is approved, but it must be approved before Authorized Instruction is issued.
The medical report is valid for six months, and Authorized Instruction must be obtained within that time.
Vision: at least 6/9 with both eyes, the worse eye at least 6/30, and a 150° visual field.
Medical reports are renewed every five years to age 45, every three years to age 64 and every year from 65.
The knowledge tests for Classes 1–4 are based on the Professional Driver's Manual and are not open book.
Class 1 road tests must be done in a manual-transmission vehicle, with a Daily Vehicle Inspection Report from the past 24 hours.
A Manitoba Class 1–4 licence is accepted as a commercial licence in the US; drivers with certain medical conditions get a Code W restriction. US rules require age 21 and a medical card.
Any vehicle with air brakes needs an air brake endorsement: a knowledge test plus a practical test (A endorsement); adjusting manual slack adjusters is the separate S endorsement.
The air brake practical demonstration is part of every Class 1 road test.
