Licence classes, endorsements and exams: 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 ↗

Ch. 1 Classified licence system (pp. 1–9)

  • You must hold the licence class for the vehicle you drive; being unpaid or not owning the vehicle is no exemption.
  • Exams are needed if you were never licensed, have not held that Saskatchewan class within five years, hold a licence Saskatchewan does not honour, want a higher class or an endorsement, or your licence is not valid.
  • Novice drivers (Class 7, or Class 5 with a Novice 1 or 2 restriction, or the out-of-province equivalent) cannot get Class 1–4, school bus or heavy trailer privileges.
  • Class 1: power units with semi-trailers, and trucks towing units heavier than 4,600 kg; also covers Classes 2–5.
  • Class 2: buses seating more than 24 passengers while carrying passengers; also covers Classes 3–5 and Class 1 as a learner with the endorsement.
  • Class 3: trucks with more than two axles (not farm-registered Class F), towing no more than 4,600 kg; power units with more than two axles when not towing a semi-trailer; also Classes 4–5.
  • Class 4: buses seating 24 or fewer while carrying passengers; taxis (PT) and rideshare (LV) carrying 9 or fewer; PB/PC vehicles carrying 24 or fewer for hire; ambulances used for hire; also Class 5.
  • Class 4 taxi, limousine and rideshare drivers file a criminal record check with their company every year; an unsatisfactory check can bring a T restriction (no passengers for hire).
  • None of Classes 1–4 allows air brakes, motorcycles or school buses without the matching endorsement.
  • Minimum age for Classes 1–4: 18, and not a novice driver.

Farm-plated vehicles and Endorsements (pp. 9–12)

  • Farm-plated 2- and 3-axle trucks, even with air brakes, can be driven on a Class 5 without the air brake endorsement.
  • A farm 2-axle power unit towing any trailer needs Class 1; a farm 3-axle power unit not towing needs Class 3 (3A with air brakes).
  • A endorsement: needed for any vehicle with air brakes, except farm-licensed Class 3 or 5 trucks; air-over-hydraulic brakes do not need it.
  • A endorsement requirements: written air brake test, adjust a manual slack adjuster on a model and explain automatic slack adjusters, practical demonstration on equipment you supply.
  • Without the A endorsement you may drive air-brake vehicles as a learner beside someone whose licence has it.
  • G endorsement (heavy trailer): towing a trailer over 4,600 kg (10,141 lb.) including its load needs Class 1 or a G endorsement on Class 2–5; G allows two-axle trucks (not power units) towing heavy trailers.
  • The 4,600 kg is the weight of the trailer(s) and contents, not the tow vehicle; two trailers are counted together.
  • S endorsement (school bus) can be added to a Class 1–5 licence; road test in the right size of bus: unrestricted means at least 36 student passengers (six rows of seats count as 36).
  • "Student passengers" means three passengers per seat.
  • Learner endorsements 1–4: age 18, not novice, written tests, vision and medical, supervised by someone who has held that class for 365 days within the last three years.

Examinations (pp. 12–15)

  • Papers: Sign 30 questions, Basic Class 5 20, Class 1 20, Class 2 15, Class 3 10, Class 4 10, Air Brake 18, Heavy Trailer 20, School Bus 15.
  • Class 1 writes Sign, Basic and the Class 1, 2, 3 and 4 papers; Class 2 writes Sign, Basic, 2, 3, 4; Class 3 writes Sign, Basic, 3, 4; Class 4 writes Sign, Basic, 4.
  • Knowledge exams may be attempted once per day; they are based on this handbook, the Saskatchewan Driver's Handbook and the Air Brake Manual.
  • Book and pre-pay on MySGI or with a motor licence issuer; walk-ins at Regina and Saskatoon Central, 8 a.m.–4 p.m., Monday to Saturday.
  • The vision test is part of the knowledge exam appointment.
  • Road tests include a highway turn-about; Class 1 adds offset and alley dock backing and coupling/uncoupling.
  • In a standard transmission for Class 1, 2, 3 or S (over 24 passengers) you must show clutch use through all gears; 13- or 18-speed: split the top range (Class 1).
  • Testing in an automatic or electronic-shift vehicle may restrict you to those transmissions.
  • A road test is rescheduled if the vehicle shows a dangerous goods placard, lacks an inspection decal, is unsafe or dirty, or the heavy trailer weighs under 4,600 kg.

Class 1-4 medical standards (pp. 16–18)

  • A Commercial Driver's Licence Medical Report must be submitted and approved before any testing.
  • Conditions that may block a commercial licence include seizures, some heart or insulin-dependent diabetic conditions, blackouts, head injuries, and vision or hearing problems.
  • Medical renewals: every five years at 18–45, every three years at 46–65, every year at 66 and older.
  • An unsatisfactory medical can bring an L restriction: no Class 2, Class 4 or rideshare vehicles.
  • Under the Canada–U.S. reciprocity agreement a valid Class 1, 2 or 3 licence proves medical fitness; Class 4 drivers of buses seating more than 10 are also covered.
  • Drivers with medical waivers get a W restriction: no commercial driving in the United States.
