This test is for vehicles over 4,500 kg in weight and buses that can carry 10 or more people (except for private use buses). When you go outside Ontario with a vehicle over 11,793 kg or over three axles, you also need the International Registration Plan (IRP) and International Fuel Tax Agreement (IFTA).

After your application is okayed, you must do a CVOR knowledge test at a DriveTest Centre in Ontario.
This test quizzes you on safety rules, vehicle care, and major safety no-noes. You need to score at least 80% to get your CVOR certificate.

The CVOR Written Examination
The CVOR written test is a key part of becoming CVOR certified. It has 30 multiple-choice questions on commercial vehicle operation. This includes safety rules, how to maintain vehicles, and road laws for big vehicles. It’s designed to ensure operators in Ontario understand their role and safety rules well.

Scheduling and Taking the Exam
The CVOR written test is given at DriveTest Centres in Ontario. Book your test online and bring your ID. To pass, you need at least 80% and you can try as many times as you need. But every new try costs money. When you pass, the DriveTest agent will tell the MTO. Then you’ll get your CVOR certificate.

Sample CVOR - Commercial Vehicle Operator’s Registration Practice Questions
Try these questions from our free CVOR - Commercial Vehicle Operator’s Registration practice tests. The correct answer and an explanation follow each question.
Trucks that have a gross weight or registered gross weight over _______ kg or tow trucks, regardless of weight, require a Commercial Vehicle Operators Registration (CVOR) certificate.
- A. 4,500
- B. 4,000
- C. 10,000
- D. 11,793
Answer: A. 4,500
Ontario law sets the CVOR threshold at 4,500 kg gross weight or registered gross weight for trucks. Tow trucks are subject to CVOR requirements regardless of their weight because of the unique safety risks they pose. The other weight options (4,000, 10,000, and 11,793 kg) are not the legislated threshold.
A carrier's driver is convicted of operating a commercial vehicle with a major defect. What is the most immediate and direct impact on the carrier's CVOR record?
- A. The carrier's safety rating is automatically downgraded to 'Conditional'.
- B. A set number of CVOR points for the severe conviction is added to the carrier's record.
- C. The MTO requires all other vehicles in the carrier's fleet to be inspected within 7 days.
- D. The carrier is immediately scheduled for a mandatory facility audit.
Answer: B. A set number of CVOR points for the severe conviction is added to the carrier's record.
Each conviction for a safety-related offence is assigned a specific point value based on its severity. A conviction for a major defect will result in points being added to the carrier's record, which directly increases their Overall Violation Rate. While this may contribute to a future rating downgrade or audit, the most direct and immediate consequence is the addition of points.
Under CVOR rules, which condition would disqualify a driver from operating a commercial vehicle?
- A. Licence suspended for demerit points
- B. Holding a Class G licence
- C. Being over age 60
- D. Having a minor traffic conviction more than 5 years ago
Answer: A. Licence suspended for demerit points
A suspended licence means the driver is legally prohibited from operating any motor vehicle, including commercial vehicles.
A driver operating a commercial vehicle subject to CVOR is found to have a blood alcohol concentration above the legal limit. What is the carrier's potential consequence?
- A. CVOR record is negatively impacted
- B. No consequence to the carrier
- C. Carrier receives a written warning only
- D. Carrier's insurance is cancelled automatically
Answer: A. CVOR record is negatively impacted
Impaired driving convictions recorded against drivers linked to a carrier's CVOR certificate contribute to the carrier's safety performance record.
