2026/2027 Edition) – 100% Correct Questions, Answers &
Detailed Rationales
Q1
A vehicle sustains damage to its front bumper cover during a collision. The estimator
reviews the damage and notes that the bumper cover has a small crack and scuff
marks but is otherwise intact. According to standard collision repair guidelines, which of
the following repair methods is most appropriate?
A) Replace the bumper cover with an OEM part
B) Repair the crack and refinish the bumper cover
C) Replace the bumper cover with an aftermarket part
D) Repair the crack but leave the scuff marks to reduce cost
Answer: B
Rationales:
● A: Replacement is unnecessary when the damage is minor and the part is
structurally sound, making this an inefficient and cost-prohibitive approach.
, ● B: Repairing the crack and refinishing the bumper cover restores the part to
pre-accident condition while adhering to standard repair-over-replace principles.
● C: Using an aftermarket part is not justified when the original part can be
economically repaired and restored to OEM specifications.
● D: Leaving scuff marks unaddressed fails to restore the vehicle to its
pre-accident cosmetic condition, violating standard repair quality requirements.
Q2
An estimator is writing a repair estimate for a 2024 sedan that requires replacement of
the left front fender. The vehicle is equipped with advanced driver-assistance systems
(ADAS), including a forward-facing camera mounted behind the windshield. Which step
must be included in the estimate?
A) Replacement of the windshield only if it is cracked
B) Calibration of the forward-facing camera after fender replacement
C) Painting of the new fender only
D) Removal and reinstallation of the front bumper only
Answer: B
Rationales:
● A: Windshield replacement is not triggered by fender replacement unless the
windshield itself is damaged, which is not indicated in this scenario.
● B: ADAS camera calibration is mandatory after any structural or sheet metal work
near the camera's mounting position to ensure proper sensor alignment and
function.
, ● C: While painting is required, omitting the calibration step would result in an
incomplete and unsafe repair estimate.
● D: Bumper R&I may be necessary for access, but it is not the critical step related
to the ADAS systems affected by this repair.
Q3
During a vehicle inspection, an estimator identifies corrosion on the inner structural rail
of a unibody vehicle. The corrosion has compromised the structural integrity of the rail.
What is the correct estimating approach?
A) Section the rail and weld in a partial replacement panel
B) Apply rust inhibitor and paint over the corrosion
C) Replace the entire rail assembly or vehicle section as specified by OEM procedures
D) Fill the corroded area with body filler and refinish
Answer: C
Rationales:
● A: Sectioning a structural rail requires strict OEM guidelines, but
corrosion-compromised metal cannot be reliably sectioned and welded to restore
structural integrity.
● B: Rust inhibitor and paint only address surface appearance and do not restore
the load-bearing capacity of a structurally compromised rail.
● C: OEM procedures require full replacement of structural components when
corrosion has compromised their integrity to ensure occupant safety and
crashworthiness.
, ● D: Body filler provides no structural strength and would create a dangerous
hidden defect in a critical safety component.
Q4
An estimator is evaluating a claim for hail damage on a 2023 pickup truck. The roof,
hood, and trunk lid have numerous small dents with no paint damage. The vehicle
owner requests paintless dent repair (PDR). What is the most accurate estimating
consideration?
A) PDR is not appropriate for hail damage and full conventional repair must be written
B) PDR is the preferred method when there is no paint damage and the dents are
accessible from the backside
C) PDR can only be used on aluminum panels, not steel
D) PDR requires drilling access holes in the panel to reach the dents
Answer: B
Rationales:
● A: PDR is a widely accepted and preferred method for hail damage when paint is
intact, making this statement factually incorrect.
● B: PDR is the optimal repair method for paint-undamaged, accessible dents
because it preserves the factory finish and is more cost-effective than
conventional repair.
● C: PDR can be performed on both steel and aluminum panels, though aluminum
requires specialized techniques, so this restriction is false.
● D: PDR does not require drilling holes; technicians use existing access points or
specialized tools to reach dents from behind without panel modification.
