Class D the misunderstood license

Ontario has several classes of licenses designed for different types of vehicle configurations.  We have looked at Class A and AR (restricted) so now is the time to look at the Class D license which often is very misunderstood.

Ontario Drivers Licence Class D

Most people start with a Class G license (G1, G2 and then G).  This is often the standard “drive the family car or pick up truck around” license.  Once you start considering driving heavier vehicles, the next class people think about is Class D.  

Class D is for bigger trucks, not trailers

Some people seem to think that with a Class D license you can tow a bigger trailer then you can with a Class G.  This is totally untrue!  A Class D is not about towing a larger, heavier trailer; it is about larger and heavier tow vehicles.

Ontario Highway Traffic Act states a Class D driver can drive “Any truck or motor vehicle combination exceeding 11,000 kg provided the towed vehicle is not over 4,600 kg”   This means, if the truck is over 11,000 kg you can drive it.

If the truck and trailer is more then 11,000 kg combined you can drive it.


The trailer itself is over 4,600 kg.

Say again!

Yes you’re limited to a towed vehicle(s) of less then 4,600 kg.  It is the exact same limit as your Class G license!

The Class D is really for bigger trucks not for bigger trailers.


Minimum requirements for Class A or D driver’s licence application

An applicant for a class A or D driver’s licence must:

  • Be at least 18 years of age
  • Hold a valid Ontario class G or higher licence or equivalent
  • Pass a test of operating knowledge of large trucks and tractor trailers
  • Meet vision standards
  • Provide a satisfactory medical certificate on application and periodically thereafter
  • Demonstrate driving competence during a road test while driving the following types of vehicles:
    • For class D – a motor vehicle exceeding 11,000 kg (24,000 lb) gross weight or registered gross weight
    • For class A – a motor vehicle and towed vehicle where the towed vehicle exceeds a total gross weight of 4600 kg (10,000 lb)

It is very important that we as drivers hold the correct license for the vehicles we are driving and or towing.  Without it we can face stiff fines and possible loss of coverage in insurance if ever in an accident.   It is our responsibility!
