Keeping your Class D licence: 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 ↗

Class D renewal

  • Since July 1, 2018, Class D drivers under 65 must pass a vision test and a knowledge test to renew.
  • Class D drivers 65 and older also renew with vision and knowledge tests, usually every five years.
  • Drivers aged 65 to 79 with Class A to F must also pass a road test after an at-fault collision or after building up three or more demerit points.
  • Drivers 80 and over with Class A, B, C, D, E or F must pass vision, knowledge and road tests before each renewal.
  • Renewals that need tests are done at a DriveTest centre; renewals without tests are done in person at ServiceOntario.
  • If you do not receive a renewal form, contact the ministry; keeping a valid licence is your responsibility.

Class D medical reports

  • Since July 1, 2018, Class D drivers must submit a satisfactory medical report periodically to keep Class D, or be downgraded to Class G.
  • Class D drivers aged 80 and older submit a medical report every year.
  • For other commercial classes the schedule is every five years under 46, every three years from 46 to 64, and every year from 65.
  • A medical notice and blank form come about three months before the report is due.

Records and documents

  • Report a change of name or address to the ministry within six days; the replacement licence is free.
  • Destroy the old licence when the new one arrives and carry the new one.
  • A licence that has been suspended, cancelled or expired for over three years means going back through graduated licensing before reapplying for any commercial class.
  • Demerit points stay on your record for two years from the date of the offence.

Other ways to lose your licence

  • Drivers of vehicles needing a Class A to F licence, of CVOR vehicles and of road-building machines must have no alcohol or drugs at all in their system.
  • Violations bring suspensions and administrative monetary penalties; impairment by any drug, including prescription or over-the-counter medicine, can lead to criminal charges and jail.
  • Police can demand breath, oral fluid, urine or blood samples, field sobriety tests or a drug-recognition evaluation; refusing is a criminal charge.
  • If you cannot give a breath sample, police can require a blood sample.
  • Ask your doctor or pharmacist about medications; drugs and alcohol together can affect you even days later.
  • Doctors must report drivers with medical conditions that may affect driving; the licence can be suspended until new evidence shows no safety risk.
