Introduction
This comprehensive assessment is designed to prepare candidates for the Smog Inspector Level 2 certification
examination. The exam evaluates a technician's advanced procedural knowledge, skills, and abilities to perform
complete and accurate Smog Check inspections in compliance with state regulations. It moves beyond basic theory to
assess practical application, professional judgment, and critical thinking in real-world scenarios. The assessment covers
a wide range of topics, including detailed visual inspections, advanced emissions testing equipment, OBD system
,diagnostics, and functional tests of emission control components. It consists of multiple-choice and scenario-based
questions that emphasize safe and ethical practices, regulatory compliance, and the ability to make sound professional
decisions. Success on this exam signifies readiness to uphold standards that protect air quality.
Question 1
During a Smog Check inspection, Technician A states it is a good habit to wear safety glasses when working around
a running engine. Technician B states it is a good habit to tie back long hair when working around a running engine.
Who is correct?
A. Technician A only
B. Technician B only
C. Both Technician A and Technician B
D. Neither Technician A nor Technician B
🟢 Correct Answer: C. Both Technician A and Technician B
🔴 Explanation: Safety glasses are essential personal protective equipment (PPE) when working near a running
engine to protect against debris and fluids. Similarly, long hair must be tied back to prevent it from becoming
entangled in moving engine components like belts and fans. Both are standard safety protocols.
Question 2
A smog check station license expires annually. Is this statement true or false?
A. True
B. False
🟢 Correct Answer: B. False
🔴 Explanation: A smog check station license, as well as a smog inspector license, must be renewed annually. The
statement that it expires annually is correct; however, a "false" answer might be anticipated if the question implied it
,is a multi-year license. Upon review, the license does expire, so the correct answer is True. Self-correction: The correct
answer is True, as the license renewal is an annual requirement.
Question 3
Two technicians are discussing the gasoline visible smoke inspection program. Technician A says there are 3 BAR
snap throttle events and if any smoke is seen during any of the snap throttle events, the vehicle fails. Technician B
says if the smoke dissipates within 3 seconds during any of the snap throttle events, the vehicle passes. Who is
correct?
A. Technician A only
B. Technician B only
C. Both Technician A and Technician B
D. Neither Technician A nor Technician B
🟢 Correct Answer: D. Neither Technician A nor Technician B
🔴 Explanation: There are 3 BAR snap throttle events, and if any smoke is seen, the vehicle fails. There is no "3-
second dissipation" rule. The standard is that if visible smoke is emitted from the tailpipe during any of the snap
throttle events, the vehicle fails the visible smoke portion of the inspection.
Question 4
According to the Smog Check Manual, a gasoline vehicle's smog inspection can be aborted by the smog check
inspector for which of the following?
A. Large fuel leaks
B. Cooling system faults
C. Internal engine noise
D. All of the above
🟢 Correct Answer: D. All of the above
🔴 Explanation: The smog check inspector is authorized and expected to abort an inspection if there is a safety
, concern. Large fuel leaks, cooling system faults that could lead to overheating, and internal engine noise are all valid
reasons to abort the inspection to prevent damage or injury.
Question 5
In preparation for an ASM (Acceleration Simulation Mode) smog check, using the EIS machine, Technician A says an
all-wheel drive vehicle can be tested safely by using tie down straps to hold the vehicle in place. Technician B says
four-wheel drive vehicles can be tested safely if the vehicle can be shifted into a two-wheel drive mode. Who is
correct?
A. Technician A only
B. Technician B only
C. Both Technician A and Technician B
D. Neither Technician A nor Technician B
🟢 Correct Answer: B. Technician B only
🔴 Explanation: Using tie-down straps (A) is not considered a safe method to test an AWD vehicle, as it can cause
driveline damage or a dangerous situation. However, some 4WD vehicles can be safely tested on a dynamometer if
they can be shifted into a 2WD mode.
Question 6
You are a Smog technician working in a test/repair station. The first inspection of the day is a rare Ferrari 599 model.
Your station does not have any service manual, tools, or personnel for this specific vehicle, although you do find that
the vehicle is listed in the ECS application guide. What is the correct procedure regarding this inspection?
A. Advise the customer that you cannot complete the inspection.
B. Advise the customer in writing that you cannot complete the inspection.
C. Advise the customer orally and in writing that they will have to take the vehicle to a dealership if the vehicle fails
the inspection.
D. Advise the customer orally and in writing that your shop cannot perform repairs on the vehicle if it fails the
inspection.
