SGI Class 1 License 3 — Questions and Answers
Question 1: Which of the following best describes 'black ice' conditions that Class 1 drivers must watch for in Saskatchewan winters?
- Thick visible ice covered with snow
- A thin transparent layer of ice that makes pavement look wet (Correct answer)
- Ice formed only on bridges and overpasses
- Dark coloured road salt residue
Correct answer: A thin transparent layer of ice that makes pavement look wet
Black ice is a thin, nearly invisible coating of ice on the road surface that appears as a wet sheen and offers almost no traction.
Question 2: What does a Class 1 driver need to know about high centre-of-gravity loads on curves?
- Heavier loads lower the centre of gravity, reducing rollover risk
- High loads shift the centre of gravity up, increasing rollover risk on curves (Correct answer)
- Speed does not affect rollover risk if cargo is properly secured
- Rollover risk only applies to empty trailers
Correct answer: High loads shift the centre of gravity up, increasing rollover risk on curves
High centre-of-gravity loads increase the risk of rollover when taking curves, especially at highway speeds.
Question 3: Under the National Safety Code, a Class 1 driver must carry a logbook for how many previous consecutive days?
- 3 days
- 5 days
- 7 days (Correct answer)
- 14 days
Correct answer: 7 days
Drivers must carry completed log records for the current day plus the previous 7 consecutive days.
Question 4: What is the correct procedure when a Class 1 driver encounters a weight scale on a Saskatchewan highway?
- Bypass the scale if the load is within legal limits
- Stop and weigh only if operating over 8,000 kg
- All vehicles subject to scale must enter when the scale is open and the light is red or flashing (Correct answer)
- Enter the scale only if a sign specifically directs your vehicle type
Correct answer: All vehicles subject to scale must enter when the scale is open and the light is red or flashing
When a weigh scale is open and displays a red or flashing signal, all applicable commercial vehicles must enter regardless of perceived weight.
Question 5: A Class 1 driver is operating on a gravel secondary highway in Saskatchewan. What should the driver be most cautious about regarding following distance?
- Gravel roads have better stopping distance than pavement
- Loose gravel reduces tire traction and increases stopping distance (Correct answer)
- Gravel highways have a higher speed limit than paved roads
- Following distance rules only apply on paved highways
Correct answer: Loose gravel reduces tire traction and increases stopping distance
Loose gravel reduces traction significantly, meaning stopping distances are much longer than on dry pavement.
Question 6: Which type of tanker rollover is most common for Class 1 drivers hauling liquid cargo in Saskatchewan?
- Front rollover caused by engine weight
- Outward rollover on curves due to liquid surge (Correct answer)
- Rear rollover from braking on hills
- Side rollover caused by crosswinds only
Correct answer: Outward rollover on curves due to liquid surge
Liquid surge in partially filled tankers shifts weight outward on curves, dramatically increasing rollover risk.
Question 7: When a Class 1 commercial vehicle is involved in a collision in Saskatchewan resulting in injury or death, within what time must the driver report to police?
- 6 hours
- 12 hours
- 24 hours
- Immediately at the scene (Correct answer)
Correct answer: Immediately at the scene
Drivers must remain at the scene and report immediately when a collision involves injury, death, or property damage over the reporting threshold.
