Prince Edward Island Commercial Licence Practice

Prince Edward Island's commercial knowledge test covers the rules and operating standards for class 1 (tractor-trailer). The test has 30 multiple-choice questions and you need at least 24 correct answers (80%) to pass. It's administered by Transportation and Infrastructure, Access PEI with no formal time limit. PEI uses numerical classes 1 and 3 plus an air-brake endorsement. Class 2 (bus) and Class 4 are administered through other classes.

Federal Hours-of-Service rules (SOR/2005-313) apply to commercial drivers across Canada and are a major topic on the test. Drivers operating in the South of 60° latitude are limited to 13 hours of driving, 14 hours on-duty, and a 16-hour driving-window in a single shift. After 70 hours on-duty in a 7-day cycle (or 120 hours in a 14-day cycle), you must take 36+ hours off. Logbooks (paper or electronic - ELDs are now mandatory for federally-regulated carriers) must be kept current.

Air-brake systems are fundamental to most heavy commercial vehicles and operate on a different principle than hydraulic brakes - air pressure releases spring-loaded brakes rather than applying them. Loss of air pressure causes spring-brake application, which is why the system "fails safe." The test covers air-brake fundamentals: governor cut-in/cut-out pressure (typically 100-125 psi), low-air warning thresholds (≈60 psi), spring-brake application thresholds (≈20-45 psi), and slack adjuster inspection.

Pre-trip inspection is one of the most important duties of a commercial driver and is heavily tested. A complete pre-trip covers: tires (tread depth, sidewall damage), wheels (lug nut visual check), brakes (slack, drum/rotor inspection, hose integrity), lights, mirrors, fluids, fifth wheel, kingpin, and trailer connections. Prince Edward Island commercial drivers who fail to perform pre-trip inspections face significant fines and can lose their commercial endorsement.

Cargo securement follows the federal National Safety Code (NSC) Standard 10 and is uniform across Canada. The standard specifies minimum tie-down requirements based on cargo weight, type, and trailer configuration. Hazardous-materials transport falls under the Transportation of Dangerous Goods (TDG) Regulations and requires additional certification beyond the basic Class 1 endorsement. Drivers transporting TDG-classified loads must carry shipping documents, display proper placards, and complete TDG-specific training every 36 months.
