Joint and Several Liability in New York and the Motor-Vehicle Exception

Joint and several liability, and the motor-vehicle exception

Practitioner note

Authority: CPLR 1601, 1602(6), 1603; Vehicle and Traffic Law §§ 388, 311; Towers v Hoag, 2007 NY Slip Op 03832.

This is the most valuable and least understood rule in New York injury practice, and the 2026 budget left it untouched.

The general rule under CPLR 1601 is a limitation, not a grant: where a defendant is found 50% or less at fault, its liability for the claimant’s non-economic loss is limited to its own equitable share. A defendant 10% at fault pays 10% of pain and suffering. That is the Article 16 regime, and it is what defense counsel will assume applies.

CPLR 1602 then lists exceptions, and the sixth is the one that matters. Article 16’s limitation does not apply to a person held liable by reason of their use, operation or ownership of a motor vehicle or motorcycle. For such a defendant, joint and several liability survives in full.

The consequence is stark and it is exactly why these cases are worth pursuing against commercial fleets. A trucking company found 1% at fault — whether through its driver’s negligence or purely as the owner of the vehicle — can be held liable for 100% of the plaintiff’s non-economic damages, with only a contribution claim against its co-defendants to recover the rest. Where the co-defendant is an uninsured or judgment-proof individual driver, that distinction decides whether the plaintiff is actually paid.

Two statutes compound this. Vehicle and Traffic Law § 388 makes the owner of a vehicle vicariously liable for the negligence of anyone operating it with permission, so the corporate owner is in the case regardless of its own conduct. CPLR 1602(6) then strips that owner of the Article 16 cap. Together they are the reason a well-pleaded commercial-vehicle case reaches a solvent defendant.

The exception must be pleaded and proved — and proved on time

Under CPLR 1603 the party asserting an Article 16 exception bears the burden of establishing it by a preponderance of the evidence. Courts have refused to let a plaintiff invoke the exception belatedly: in Denio v. State a request made eighteen months after the liability trial was held barred as prejudicial. Plead § 1602(6) from the outset.

"Motor vehicle" is a defined term, and narrower than it sounds

The exception borrows the definitions in Vehicle and Traffic Law §§ 311 and 125. In Towers v Hoag the Appellate Division held a Fire Department vehicle was not a "motor vehicle" within § 311, so the exception did not apply. Confirm the vehicle class before relying on § 1602(6).

It can reach out-of-state accidents

In Shaw v. Coach the court applied New York’s § 1602(6) exemption to a New York plaintiff’s action arising from a New Jersey accident, where New Jersey’s apportionment rules differ. Choice of law is worth briefing where the plaintiff is a New York domiciliary.

Economic damages were never capped

Article 16 limits liability for non-economic loss only. Medical expenses and lost earnings remain subject to joint and several liability against every liable defendant regardless of share.

Doctrines that make New York different

Practitioner note

Authority: Labor Law §§ 200, 240(1), 241(6); Vehicle and Traffic Law § 388; CPLR 4545.

Several New York rules have no real counterpart across the state line, and they are the reason venue and choice of law are worth litigating.

Vehicle and Traffic Law § 388 — owner liability

The owner of a vehicle is vicariously liable for the negligence of any person operating it with the owner’s express or implied permission. Combined with the CPLR 1602(6) exception to Article 16 above, this is what puts a solvent corporate owner on the hook for the full non-economic loss even where its own share of fault is nominal.

Labor Law § 240(1) — absolute liability on construction sites

New York imposes absolute, non-delegable liability on owners and general contractors for gravity-related construction injuries, and a plaintiff’s own comparative negligence is no defence. No neighbouring state has an equivalent. Because it interacts with Article 16 and with the workers’-compensation bar, it is treated in full on its own page rather than summarised here.

General Obligations Law § 11-101 — the Dram Shop Act

A person injured by an intoxicated individual has a direct statutory claim against whoever unlawfully sold or furnished the alcohol. This is a cause of action independent of ordinary negligence, and it reaches a commercially insured defendant in drunk-driving cases where the driver is judgment-proof.

Agriculture and Markets Law § 123 — dog bites

New York is a hybrid jurisdiction for animal injuries: the owner of a dog previously determined to be "dangerous" is strictly liable for medical costs, while a claim beyond that requires proof the owner knew of the animal’s vicious propensities. New York does not apply a general one-bite strict-liability rule.

No general damages cap

New York imposes no general cap on non-economic damages. The single exception, added in May 2026, is the $100,000 cap in Insurance Law § 5104(d) for certain at-fault uninsured or convicted claimants.
