Question 2: A Class 1 driver is transporting dangerous goods placarded FLAMMABLE GAS. Which document must accompany the shipment?
- A cargo manifest signed by the shipper
- A Transport Canada shipping document (bill of lading) with dangerous goods information (Correct answer)
- A federal highway permit

Correct answer: A Transport Canada shipping document (bill of lading) with dangerous goods information
Transportation of Dangerous Goods (TDG) regulations require a shipping document detailing the dangerous goods classification, UN number, quantity, and shipper information.
Question 3: What is 'off-tracking' and why is it important for a Class 1 driver making a right turn in a city?
- Off-tracking is when the trailer tires follow a wider arc than the tractor, requiring the driver to swing wide before turning
- Off-tracking is when the trailer tires cut inside the tractor's path, requiring extra caution for curbs (Correct answer)
- Off-tracking only occurs during lane changes on highways
- Off-tracking causes the trailer to push to the outside only at highway speeds
Correct answer: Off-tracking is when the trailer tires cut inside the tractor's path, requiring extra caution for curbs
Trailer rear tires track inside the front tractor tires on turns, so drivers must account for the trailer sweeping the curb or hitting obstacles inside the turn.
Question 4: When parking a Class 1 combination vehicle on a grade, what is the correct sequence for applying the parking brakes?
- Apply spring parking brakes first, then chock wheels
- Stop with service brakes, apply spring parking brakes, chock wheels if required (Correct answer)
- Chock wheels first, then apply spring brakes
- Apply trailer brakes only and leave tractor in gear
Correct answer: Stop with service brakes, apply spring parking brakes, chock wheels if required
The correct sequence is to stop using service brakes, then apply spring parking brakes, and chock wheels when required by grade or conditions.
Question 5: A Class 1 driver in Saskatchewan must carry proof of a valid medical fitness certificate. How often must the medical examination be renewed for drivers under age 46?
- Every year
- Every 2 years (Correct answer)
- Every 3 years
- Every 5 years
Correct answer: Every 2 years
Commercial drivers under age 46 must renew their medical fitness certificate every 2 years; frequency increases with age.
Question 6: What is the correct action when a Class 1 driver's trailer begins to skid sideways (trailer jackknife) on a slippery road?
- Apply full brakes and steer away from the skid
- Release the brakes to allow wheels to rotate and regain traction, then gently steer to straighten (Correct answer)
- Accelerate to pull the trailer straight
- Apply only the trailer hand brake to correct the skid
Correct answer: Release the brakes to allow wheels to rotate and regain traction, then gently steer to straighten
Releasing brake pressure allows locked trailer wheels to spin again, restoring traction and allowing the trailer to straighten behind the tractor.
Question 7: Under Saskatchewan law, what is the minimum following distance a Class 1 driver must maintain at highway speeds under normal conditions?

- At least 2 seconds behind the vehicle ahead
- 60 metres at all times
- At least 4 seconds behind the vehicle ahead for commercial vehicles (Correct answer)
Correct answer: At least 4 seconds behind the vehicle ahead for commercial vehicles
Commercial vehicle drivers should maintain a minimum 4-second following distance under normal conditions to account for longer stopping distances.
