Getting and renewing the Z endorsement: 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 ↗

Who needs it

  • In Ontario you need a Z endorsement on your licence to drive a vehicle with air brakes or air-over-hydraulic brakes.
  • You can earn it by taking an air brake endorsement course, or by taking the tests at a DriveTest centre.
  • The Official Air Brake Handbook is the study guide for the knowledge test; it is free online or can be bought in print.

Courses

  • Courses are offered by vehicle fleet owners, community colleges and safety organizations.
  • Class A holders upgrading to Z can use any of those three; holders of B, C, D, E, F or G must take the course with a fleet owner.
  • After the course you receive a referral envelope, which must be taken to a DriveTest centre within 6 months.

Tests

  • The knowledge test is taken at a DriveTest centre and requires a fee; after passing it you book the practical test.
  • There are two practical test versions: Version 1 for vehicles with a tractor-trailer air brake system, Version 2 for other air-braked vehicles.
  • Bring wheel chocks, a stopwatch or watch with a second hand, knowledge of every brake chamber's size and type, something to hold the pedal applied, a way to mark the pushrod, a stroke-measuring device and protective eyewear (the last three are not needed for motor coaches); a brake adjustment chart is optional.
  • On the practical test, tell the examiner what you are testing at each step.
  • Cancel a test at least 48 hours ahead to avoid a cancellation fee.

Renewal

  • Since September 1, 2023, renewing a licence with a Z endorsement requires completing an online air brake learning module instead of the air brake knowledge test.
  • Bring the certificate of completion (digital or printed) and your licence to a DriveTest centre or your Driver Certification Program organization.
  • Commercial-class holders also complete the vision and commercial knowledge tests in person when renewing.
  • From age 80, the learning module and the practical test are required every year; under 80, renewal is usually every five years.
  • If you cannot do the module online, you can complete it in person at a DriveTest centre.
