- Direct damage
- Damage that occurs at the point of impact where the colliding object first contacts the vehicle. Usually the most obvious damage to identify.
- Indirect damage
- Damage that occurs away from the point of impact as collision energy travels through the vehicle structure (buckled floors, popped welds, misaligned gaps).
- Primary damage
- Damage produced by the initial impact itself at the point of contact. Often used interchangeably with direct damage.
- Secondary damage
- Damage that occurs after the initial impact, such as the vehicle striking a second object or energy traveling onward through the structure.
- Inertia damage
- Damage caused by heavy components (engine, transmission, battery) continuing their motion after the vehicle suddenly stops, stressing or breaking their mounts.
- Hidden damage
- Damage that cannot be seen during the initial visual inspection and is only revealed after parts are removed during teardown/disassembly.
- Teardown (disassembly)
- Removing damaged and adjacent parts to expose and document all damage before writing the complete repair plan, so hidden damage is found early.
- Blueprinting (repair planning)
- Thorough disassembly and inspection that produces a complete repair plan and a 100 percent accurate estimate before repairs begin.
- Direction of impact
- The angle and path the force took into the vehicle; analyzing it lets the technician trace the energy and predict where indirect damage occurred.
- Collision energy
- The kinetic energy transferred into a vehicle during impact; it travels along structural paths, so damage severity generally decreases with distance from the point of impact.
- Structural damage
- Damage to load-bearing parts such as rails, pillars, rockers, and the floor pan that affects the vehicle's strength and dimensions.
- Non-structural damage
- Damage to bolt-on or cosmetic parts (fenders, doors, bumper covers) that does not affect the vehicle's load-bearing structure.
- Three-dimensional measurement
- Measuring length, width, and height of structural points against factory specs to find frame/unibody misalignment that the eye cannot detect.

- A structural condition where a section of the frame/rail is bent downward below its normal height.
- Sway damage
- A structural condition where a section of the frame/structure is pushed sideways, left or right of centerline.
- Twist damage
- A structural condition where one corner of the vehicle is higher and the diagonal corner lower, so the structure is no longer flat.
- Prior (pre-existing) damage
- Damage or repairs that existed before the current collision; it must be identified and excluded so the customer/insurer is not billed for it.
- Damage zones
- Dividing the vehicle into areas (front, rear, sides, structural) to systematically inspect and document all damage during analysis.
- Radiator support displacement
- Movement of the radiator support after a frontal hit; because it is fixed to the structure, its shift can signal frame/rail damage.
- Visual inspection
- The first damage-analysis step: looking over the vehicle for obvious crush, gaps, cracks, fluid leaks, and clues to the energy path.
- Paint cracking/flaking at impact
- Surface cracking that can reveal body filler or previous repair work hidden beneath the paint at the impact site.
- Flood damage indicators
- Corrosion, mud/silt lines, and electrical malfunctions; hidden electrical-system damage is a primary concern in flood-damaged vehicles.

- Checking the undercarriage (exhaust, floor pan, rails, suspension mounts) for damage that is not visible from above after a collision.
- Tracking / tram gauge
- A measuring tool used to check point-to-point and diagonal (cross) dimensions to detect frame misalignment.

- The route collision force follows through the vehicle's structure; following it locates indirect and hidden damage beyond the obvious crush.
