About the SK Class 1 Commercial Exam

The Saskatchewan Class 1 commercial knowledge pathway is SGI's written testing sequence for drivers preparing to operate power units and semi-trailers and other Class 1 combinations. Official Class 1 requirements include multiple knowledge papers (Class 1, 2, 3, 4, Basic and Sign), medical and vision screening, Mandatory Entry-Level Training before the road test, a Class 1 trip inspection, coupling and uncoupling, and a road test in a three-axle power unit with a minimum 48 ft trailer. Because Class 1 vehicles are typically air-brake equipped, applicants also need the A air-brake endorsement.

Assessment

Class 1 knowledge tests include Class 1, 2, 3, 4, Basic and Sign papers based on the Professional Driver's Handbook, Saskatchewan Driver's Handbook, and Air Brake Manual. The Class 1 licence path also requires vision testing, MELT before the road test, a Class 1 trip inspection, coupling/uncoupling, and a Class 1 road test; air-brake endorsement testing is separate.

SK Class 1 Commercial Study Tips from Top Performers

1Start with SGI's Class 1 page and the Professional Driver's Handbook chart so you know every required paper: Class 1, 2, 3, 4, Basic and Sign.
2Memorize the logistics numbers: Class 1 paper 20 questions, 80% pass, $25 written fee, knowledge attempts once per day, and 121.5-hour MELT split.
3Drill air-brake numbers from the SGI Air Brake Manual: cut-out 120–145 psi, cut-in 100 psi minimum, low-air warning at 60 psi, tractor protection at 20 psi.
4Practise trip-inspection decisions: major defects ground the vehicle; minor defects must be repaired before the next trip inspection; record all required report fields.
5Use the length÷3 following-distance method for semis and lengthen the count in rain, snow, or ice; do not draft in illegal caravans.
6Finish with mixed sets that jump between licensing, air brakes, coupling, cargo, signs, and emergency decisions the way SGI papers and MELT modules do.
