Introduction
This comprehensive examination is designed to assess the competency of candidates for the Alberta Automotive
Service Technician Red Seal certification. It evaluates the essential skills, technical knowledge, and diagnostic
abilities required for success in the trade . The exam is structured to cover a wide range of topics, from
foundational theory and applied professional knowledge to regulatory compliance and ethical practice. It
employs a multiple-choice format with scenario-based questions that emphasize real-world application, critical
thinking, and effective problem-solving in the repair and maintenance of automotive vehicles and light trucks .
Mastery of these areas is crucial for ensuring safety, reliability, and efficiency in the automotive service industry.
SECTION ONE: QUESTIONS 1 – 100
,1. Who is ultimately responsible for maintaining a safe work environment in an automotive service shop?
A. The shop owner
B. The Occupational Health and Safety department
C. Every technician and employee
D. The service manager
🟢C
🔴 Explanation: Safety is a shared responsibility, but every technician and employee has a personal duty to
follow safety protocols, use PPE, and report hazards. While management provides the framework, individual
actions determine a safe workplace.
2. What is the correct procedure for preparing an engine hoist to lift an engine?
A. Draw the legs of the hoist in, then extend the lift arm to access the engine.
B. Extend the legs as far as possible, then pull the lifting arm in for stability.
C. Adjust the leg length and then adjust the lift beam length to lift the engine.
D. Adjust the engine hoist to carry the engine as low as possible, then lift the engine.
🟢C
🔴 Explanation: The legs must be extended and the lift beam adjusted to distribute the heavy engine load
safely and maintain stability . The hoist should be positioned so the load is centered and the machine is on a
stable, level surface.
3. What is the primary function of the oxygen sensor (O2 sensor) in a modern vehicle?
A. Measure fuel pressure
B. Monitor exhaust oxygen levels
C. Control engine temperature
D. Regulate coolant flow
,🟢B
🔴 Explanation: The oxygen sensor monitors the amount of oxygen in the exhaust stream to help the engine
control module (ECM) optimize the fuel-air mixture for efficiency and emissions control .
4. A MacPherson strut suspension system combines a shock absorber with which other component?
A. A leaf spring
B. A torsion bar
C. A coil spring
D. An air spring
🟢C
🔴 Explanation: A MacPherson strut is a compact suspension design that combines a shock absorber and a
coil spring into a single unit, which also serves as a pivot point for the steering .
5. What is the primary purpose of a catalytic converter?
A. Increase engine horsepower
B. Reduce fuel consumption
C. Convert harmful gases into less harmful emissions
D. Filter particulate matter from the air intake
🟢C
🔴 Explanation: Catalytic converters convert harmful exhaust gases like carbon monoxide and hydrocarbons
into less harmful emissions such as carbon dioxide and water vapor .
6. A customer reports that their headlights dim at idle but brighten when the engine is revved. What is the
most likely cause?
A. Engine overheating
B. A failing alternator
, C. Excessive exhaust smoke
D. Hard steering
🟢B
🔴 Explanation: A failing alternator may not produce sufficient voltage at idle to power the vehicle's
electrical system, causing lights to dim . The higher RPM increases alternator output, temporarily improving
the condition.
7. In a hydraulic brake system, what is the role of the master cylinder?
A. Store brake fluid
B. Convert pedal force into hydraulic pressure
C. Act as a pressure relief valve
D. Regulate ABS sensors
🟢B
🔴 Explanation: When the brake pedal is pressed, the master cylinder converts mechanical force into
hydraulic pressure, forcing brake fluid through the lines to actuate the brakes .
8. A vehicle engine is equipped with a liquid-cooled system. What component circulates the coolant?
A. Water pump
B. Thermostat
C. Radiator cap
D. Coolant sensor
🟢A
🔴 Explanation: The water pump is the heart of the liquid-cooling system, circulating coolant through the
engine block, cylinder head, and radiator .
