CAADE Vehicle Damage Identification 2 — Questions and Answers
Question 1: Which term describes damage that is visible only after disassembly of a component or panel?
- Primary damage
- Induced damage
- Hidden damage (Correct answer)
- Residual damage
Correct answer: Hidden damage
Hidden damage is concealed behind or beneath components and is only revealed during teardown or disassembly.
Question 2: A vehicle's unibody frame shows a 'diamond' distortion. What does this indicate?
- A minor side impact
- A frontal offset collision
- A twisting force applied diagonally across the structure (Correct answer)
- Thermal expansion from fire damage
Correct answer: A twisting force applied diagonally across the structure
Diamond distortion results from a diagonal force that causes the body to twist so that one corner is pushed forward or backward relative to the opposite corner.
Question 3: When appraising hail damage, which tool is most appropriate for measuring individual dent depth?
- Tram gauge
- Ultrasonic thickness gauge
- Depth gauge (PDR dent gauge) (Correct answer)
- Laser measuring system
Correct answer: Depth gauge (PDR dent gauge)
A PDR dent depth gauge measures the depth of individual hail dents accurately, which is critical for estimating repair costs.
Question 4: What type of damage occurs in body panels adjacent to the primary impact zone due to transferred energy?
- Secondary damage (Correct answer)
- Crush damage
- Cosmetic damage
- Subsurface damage
Correct answer: Secondary damage
Secondary damage occurs in areas surrounding the primary impact point as collision energy transfers through the structure.
Question 5: A door gap that is wider at the top than at the bottom on one side is most indicative of which structural condition?
- Sag damage (Correct answer)
- Twist damage
- Mash damage
- Sidesway damage
Correct answer: Sag damage
Sag damage causes the roof to drop downward, which results in door openings that are wider at the top than the bottom.
Question 6: Which of the following paint defects is most commonly associated with collision repair that used improper heat during curing?
- Orange peel
- Fisheyes
- Blistering (Correct answer)
- Solvent popping
Correct answer: Blistering
Blistering in paint is typically caused by excessive heat during curing, which traps solvents or moisture beneath the film.
Question 7: Corrosion found between two overlapping metal panels is known as:
- Galvanic corrosion
- Crevice corrosion (Correct answer)
- Pitting corrosion
- Filiform corrosion
Correct answer: Crevice corrosion
Crevice corrosion occurs in confined spaces between overlapping metal surfaces where moisture and contaminants accumulate.
