1What is the minimum age requirement to obtain a Class 1 commercial driver's licence in Saskatchewan?

A.16 years old

B.18 years old

C.21 years old

D.25 years old

Explanation: In Saskatchewan, you must be at least 18 years of age and hold a valid Class 5 or higher licence to apply for a Class 1 driver's licence. This ensures the applicant has basic driving experience before operating heavy commercial vehicles.

2Which of the following vehicles requires a Class 1 licence to operate in Saskatchewan?

A.Any power unit and semi-trailer combination

B.A standard two-axle passenger bus

C.A two-axle delivery truck weighing over 5,000 kg

D.A motorcycle

Explanation: A Class 1 licence in Saskatchewan allows the operation of power units and semi-trailers, as well as trucks towing trailers where the trailer's gross weight exceeds 4,600 kg. Other vehicles, like buses or delivery trucks, are covered by Class 2 or Class 3 licences unless towing heavy trailers.

3What is the blood alcohol concentration (BAC) limit for commercial drivers operating a Class 1 vehicle in Saskatchewan?

A.0.08%

B.0.05%

C.0.00%

D.0.02%

Explanation: In Saskatchewan, commercial drivers are subject to a zero-tolerance policy. This means they must maintain a 0.00% blood alcohol concentration (BAC) while operating any commercial vehicle.

4Which component of the air brake system is responsible for storing pressurized air?

A.The air compressor

B.The brake chambers

C.The air reservoirs (tanks)

D.The governor

Explanation: Air reservoirs are specialized storage tanks designed to hold compressed air for the braking system. They ensure that a sufficient volume of air is immediately available to apply the brakes when needed.

5What colour is the trailer supply valve on the tractor dashboard?

A.Red octagon

B.Yellow diamond

C.Blue circle

D.Green square

Explanation: The trailer supply valve on the dashboard of a tractor-trailer is a red, eight-sided (octagon) knob. Pulling this knob out cuts off the trailer air supply and applies the trailer spring parking brakes.

6According to Saskatchewan cargo securement rules, what is the minimum number of tiedowns required for an article of cargo that is 1.5 metres or less in length and weighs 228 kg?

A.One tiedown

B.Two tiedowns

C.Three tiedowns

D.Four tiedowns

Explanation: For cargo securement, if an article is 1.52 metres (5 feet) or less in length and weighs 500 kg (1,100 lbs) or less, it requires a minimum of one tiedown.

7Which of the following is considered a 'minor defect' during a commercial vehicle pre-trip inspection?

A.A flat tire

B.A leaking wheel hub oil seal

C.A broken leaf spring that allows the axle to shift

D.An inoperative horn

Explanation: An inoperative horn is classified as a minor defect under standard National Safety Code (NSC) inspection schedules. The driver must record the minor defect and report it, but they are not required to put the vehicle out of service immediately.

8When backing a tractor-trailer, which direction is it generally safest and easiest to turn the trailer?

A.Toward the passenger side (blind-side backing)

B.Toward the driver's side (sight-side backing)

C.Straight back without turning

D.Alternating directions continuously

Explanation: Sight-side backing (backing toward the driver's side) is much safer and easier because the driver can look directly out the window and see the rear of the trailer clearly. Blind-side backing relies heavily on mirrors and is far more dangerous.

9What does a flashing green light (or flashing green left-turn arrow) at an intersection in Saskatchewan indicate?

A.You have a protected left turn - oncoming traffic is stopped, so left-turning drivers may proceed

B.Pedestrians have the right of way to cross in every direction at once

C.Emergency vehicles are approaching the intersection

D.The signal is defective and must be treated as a four-way stop

Explanation: In Saskatchewan, a flashing green light or flashing green left-turn arrow gives left-turning drivers the right of way: oncoming traffic is being held at a red light, so you may complete your left turn without yielding. (This differs from British Columbia and Yukon, where a flashing green ball marks a pedestrian-controlled intersection.)

10What is 'off-tracking' (also known as cheat) when referring to a turning commercial vehicle?

A.The front wheels sliding on wet pavement

B.The path of the rear wheels being different from the path of the front wheels

C.The trailer tipping over during a sharp turn

D.The engine losing traction when pulling a hill

Explanation: Off-tracking occurs when a vehicle turns and the rear wheels do not follow the exact path of the front wheels, instead cutting inside the turn. The longer the distance between the front wheels and the rear axle, the greater the off-tracking.

About the SGI Class 1 Exam

The Saskatchewan Class 1 commercial licence written exam is administered by SGI. It evaluates candidates on the SGI Professional Driver's Handbook and air brake operating principles. The tests cover rules of the road, tractor-trailer coupling and uncoupling, vehicle off-tracking, backing procedures, National Safety Code Schedule 1 inspections (identifying major and minor defects), cargo securement rules (tiedown spacing and working load limits), and Hours of Service regulations (daily driving, on-duty, off-duty limits, Cycle 1 and Cycle 2). Passing the written test is a mandatory step before completing Class 1 MELT training and the road examination.

SGI Class 1 Study Tips from Top Performers

1Read the SGI Professional Driver's Handbook and the Air Brake Manual thoroughly before attempting the exam.

2Memorize the differences between major and minor vehicle defects. Minor defects must be logged and reported, whereas major defects put the vehicle out of service immediately.

3Learn the mathematical rules for cargo securement: remember that the aggregate working load limit of all tiedowns must equal at least 50% of the cargo weight.

4Understand Hours of Service: know that in Canada, the maximum daily driving time is 13 hours and the maximum daily on-duty time is 14 hours.

5Practice braking dynamics: learn how compressor cut-in (SGI minimum 100 psi) and cut-out (120-145 psi) pressures behave, and how low-air warning devices function.

Frequently Asked Questions

Do I need to take a separate air brake test for a Class 1 licence?

Yes. In Saskatchewan, a Class 1 licence requires operating vehicles with air brakes. You must pass the air brake written exam and a practical test in addition to the Class 1 rules of the road exam.

What is the Class 1 MELT requirement in Saskatchewan?

Saskatchewan requires all new Class 1 drivers to complete the Mandatory Entry-Level Training (MELT) program. The course consists of 121.5 hours of training combining classroom, yard, and behind-the-wheel instruction.

What is the passing score for the written exams?

The passing score is 80% on each section of the written exams. If you fail a section, you only need to retake that specific section and pay the $25 CAD fee again.

Can I take the exam online?

No. SGI commercial driver licensing written exams must be taken in person at an SGI examination office or motor licence issuer that offers testing services.
