2.5 Vehicle Parts and Construction, Repair Terminology, Regulation 79 Inspections, Rideshare & Supplemental Spousal Liability
Key Takeaways
- Body-on-frame construction places a separate body on a ladder frame, while unibody construction integrates rails, floor pan, rocker panels and pillars into one stressed shell that must be measured three-dimensionally after a collision.
- Fenders, hoods, doors and deck lids are bolted, but quarter panels and roofs are welded — writing one converts a cosmetic repair into a structural operation.
- Boron and ultra-high-strength steel components generally must be replaced rather than heated or straightened, and aluminium repair requires isolated tooling and a segregated work area.
- Regulation 79 (11 NYCRR Part 67) requires a photo inspection within 14 calendar days of the effective date before physical damage coverage attaches to a private passenger auto, with waivers including vehicles at least seven model years old and new unused dealer purchases.
- VTL § 1693 sets rideshare limits of 75/150/25 with UM and PIP in Period 1 and $1,250,000 combined with $1,250,000 SUM and PIP in Period 2; Insurance Law § 3420(g) requires supplemental spousal liability unless declined in writing, and § 2610 bars the insurer from requiring a particular repair shop.
Vehicle Parts and Construction, Repair Terminology, Regulation 79 Inspections, Rideshare & Supplemental Spousal Liability
Exam Focus: The Series 17-70 outline devotes an unusually long list to vehicle parts and construction — body panels, substructure, mechanical systems, glass, interior and paint. New York is one of the few states that tests it on a general adjuster exam, because the general license in 11 NYCRR 26.3(j) carries the automobile authority in 26.3(d). Learn the panel names and the frame versus unibody distinction; then add the three New York statutory items at the end of this section.
Body Construction: Frame vs. Unibody
Body-on-frame construction places a separate body on a full perimeter or ladder frame. Most full-size pickups and some SUVs are still built this way. Frame damage is measured and corrected on a frame rack, and the frame can often be straightened.
Unibody (unitised) construction integrates the body panels and structural members into a single stressed shell, with front and rear rails, a floor pan, rocker panels and pillars carrying the loads. Almost every modern passenger car and crossover is unibody. Two consequences drive claim value:
- Collision energy travels through the structure, so a moderate-looking impact can misalign a distant point. Unibody repair requires three-dimensional measuring against factory specifications.
- Manufacturers specify sectioning locations and prohibit straightening of certain members, so some damage requires replacement of a structural component rather than repair.
Advanced Body Materials
Modern vehicles mix mild steel, high-strength steel (HSS), ultra-high-strength steel (UHSS), boron steel, aluminium and composites. The consequences for the estimate are real: boron and UHSS components generally may not be heated or straightened and must be replaced; aluminium repair requires isolated, dedicated tooling and a segregated work area to avoid galvanic corrosion and dust contamination. An estimate that writes “repair” on a boron B-pillar is not a low estimate — it is an unsafe one.
Body Panels and Structure
| Region | Components |
|---|---|
| Front end | Bumper cover and reinforcement, grille, hood, headlamp assemblies, radiator core support, fenders, front rails |
| Cowl | The structural panel between the hood and the windshield, housing the HVAC intake and wiper mechanism; cowl damage frequently means structural involvement |
| Doors | Outer skin, inner structure, intrusion beam, regulator, glass, mirror, handle and latch |
| Quarter panels | The rear outer body panels — welded, not bolted, so replacement is a structural operation, unlike a fender |
| Rear body | Deck lid or liftgate, rear body panel, tail lamps, rear bumper cover and reinforcement, rear rails |
| Roof | Roof panel, roof rails, header; roof replacement on a unibody is major structural work |
| Pillars | A-pillar (windshield), B-pillar (between front and rear doors), C-pillar (rear); frequently UHSS or boron |
| Rocker panels | The structural sills below the doors |
| Floor pan | The stamped floor structure; pan damage indicates severe energy transfer |
| Substructure | Rails, crush zones, aprons, cross-members — the load path beneath the cosmetic panels |
| Bumpers | Cover (commonly urethane or thermoplastic, often repairable), absorber, and reinforcement bar |
| Lamps | Headlamps, tail lamps, markers — increasingly sealed LED or adaptive units carrying high part costs |
Scoping Rule of Thumb: fenders, hoods, doors and deck lids are bolted and typically replaceable without structural work. Quarter panels and roofs are welded; writing one of them changes the job from cosmetic to structural, and pulls in corrosion protection, seam sealer and — on many vehicles — pre- and post-repair scanning.
Mechanical Systems
| System | What an adjuster checks |
|---|---|
| Engine | Impact damage, mounts, oil pan, accessory drive; pre-existing mechanical condition is not a collision loss |
| Cooling | Radiator, condenser, fan assembly, hoses — commonly damaged in front impacts |
| Electrical / computers | Modules, wiring harnesses, sensors; modern vehicles require pre- and post-repair diagnostic scans and often ADAS calibration after a windshield, bumper or mirror is disturbed |
| Exhaust | Manifold, catalytic converter (a theft-target part), muffler, hangers |
| Fuel | Tank, lines, pump — any breach is a safety hold on the file |
| Heating and air conditioning | Evaporator, compressor, condenser, blower; refrigerant recovery and recharge are separate labour operations |
| Brakes / ABS | Rotors, calipers, lines, ABS module and wheel speed sensors |
| Steering | Rack, column, tie rods; a bent steering component signals structural involvement |
| Suspension | Control arms, struts, springs, knuckles, subframe; a four-wheel alignment is routine after suspension work |
| Transmission | Case, mounts, lines, cooler |
| Air bags / SRS (and seat belts) | Deployed modules, clock spring, pretensioners and the control module. Deployment is a major cost driver and often pushes a vehicle toward total loss |
| Glass | Windshield (bonded and structural on most vehicles, and a camera mount for ADAS), tempered side and back glass |
| Interior | Seats, headliner, trim, carpet, instrument panel |
| Paint | Single-stage, two-stage (base coat / clear coat) and three-stage (tri-coat) pearl; refinish time is written per panel with blend allowances, and colour match on a tri-coat requires a spray-out card |
Regulation 79: Mandatory Photo Inspection (11 NYCRR Part 67)
New York is one of a handful of states requiring a pre-insurance inspection before physical damage coverage attaches to a private passenger automobile. The authority is Insurance Law § 3411 and Regulation 79, 11 NYCRR Part 67.
- Scope. A private passenger automobile for this purpose is an owned or leased four-wheeled motor vehicle — including station wagons, jeep-type vehicles, pickups, panel trucks, delivery sedans and vans — except vehicles weighing more than 6,500 pounds unloaded (11 NYCRR 67.1(a)).
- The requirement. Where physical damage (collision or other than collision) coverage is written, the vehicle must be inspected and photographed. The inspection must be completed within 14 calendar days after the effective date of coverage; if it is not, physical damage coverage is suspended until it is done.
- Waivers (11 NYCRR 67.3). The insurer may waive the inspection where, among other grounds, the automobile is at least seven model years old on the effective date of the physical damage coverage, or the vehicle is new and unused and purchased from a dealer with acceptable documentation, or the placement involves an additional or replacement vehicle in the circumstances the regulation describes.
Claims Consequence. The first thing a New York physical damage adjuster checks on an early-term collision claim is whether the Regulation 79 inspection was completed or properly waived. If it was not, physical damage coverage may never have attached — and that is a coverage question, not a damage question.
Transportation Network Companies (Vehicle and Traffic Law Article 44-B)
New York recognised rideshare in VTL Article 44-B, and VTL § 1693 sets the financial responsibility requirements in two periods. This matters to a general adjuster because a personal auto policy may exclude coverage while the vehicle is used as a TNC vehicle in either period.
| Period 1 — logged on, no prearranged trip | Period 2 — engaged in a prearranged trip | |
|---|---|---|
| Liability | At least $75,000 per person / $150,000 per accident bodily injury and $25,000 property damage (“75/150/25”) | At least $1,250,000 combined for bodily injury, death and property damage |
| Uninsured / SUM | UM coverage required | SUM of $1,250,000 required |
| No-fault | PIP required | PIP required |
The coverage may be supplied by the TNC's group policy, by the driver's own policy, or by a combination. A driver must in all events still carry an Article 6 owner's policy for the vehicle.
Coverage Gap Cue: if the fact pattern says the driver was “waiting for a ping” with the app on, that is Period 1, and the personal policy has probably excluded it — look to the TNC group policy at the 75/150/25 level. If the driver had accepted a ride or had a passenger aboard, that is Period 2 at the $1,250,000 level.
Two More New York Statutory Items
Supplemental Spousal Liability (Insurance Law § 3420(g))
At common law New York's interspousal rule meant a standard auto policy did not cover liability of one spouse to the other. Section 3420(g) requires every motor vehicle liability policy issued or renewed in New York to include supplemental spousal liability coverage — which extends the policy's bodily injury liability limits to a claim by one spouse against the other — unless the named insured declines it in writing. On a New York file involving spouses in the same vehicle, confirm whether the coverage was declined before denying.
Choice of Repair Shop (Insurance Law § 2610)
An insurer may not require that repairs be made in a particular place or shop or by a particular concern. If the insured asks, the insurer must tell the insured of the right to have repairs made in the shop of the insured's choice, and must pay the reasonable cost of repair regardless of where it is done. Coupled with Regulation 64 § 216.7, this is New York's anti-steering framework: the adjuster may recommend a direct-repair shop, but may not condition payment on its use.
An estimate on a late-model unibody sedan writes “repair” on a boron-steel B-pillar and “replace” on the quarter panel. What is the correct assessment?
A rideshare driver in Albany has the app on and is waiting for a request when he rear-ends another vehicle. His personal auto policy excludes coverage while the vehicle is used as a TNC vehicle. What coverage level applies under Vehicle and Traffic Law § 1693?
