New Jersey Left-Turn Accident Fault: When Is the Other Driver 100% Liable?

PERSONAL INJURY LAW · SONG LAW FIRM COLUMN

Situation

A significant share of intersection collisions in New Jersey involve a driver attempting a left turn — most notably an unprotected left turn — against oncoming through traffic. At first glance the left-turning driver may appear entirely at fault. In practice, the actual apportionment of fault depends on signal state, speeds, road conditions, and eyewitness testimony, and it can shift dramatically once the full evidence is developed.

Legal Concept

New Jersey's core rule is that a left-turning driver must yield the right-of-way to any oncoming vehicle traveling straight or turning right, unless a dedicated protected-left signal (green arrow) grants priority. Failing to yield ordinarily assigns primary liability to the left-turning driver.

However, New Jersey follows Modified Comparative Negligence with a 51% bar (N.J.S.A. 2A:15-5.1). This means an oncoming through driver can still bear a share of fault if that driver contributed to the collision through speeding, running a red light, texting, or impaired driving. The left-turner's share of liability is reduced proportionally.

NJ Rules

Key statutes to be aware of:

• N.J.S.A. 39:4-90 — duty to yield when turning left at an intersection
• N.J.S.A. 39:4-98 — obligation to maintain a reasonable and prudent speed
• N.J.S.A. 39:4-97.3 — prohibition on handheld cell phone use while driving
• N.J.S.A. 2A:15-5.1 — Modified Comparative Negligence 51% Rule

The 51% Rule is decisive. If the injured plaintiff is found 51% or more at fault, recovery is completely barred. At 50% or less, the plaintiff recovers, but their damages are reduced by their own percentage. In left-turn cases, small evidentiary differences that move fault from 50% to 51% often mean the difference between substantial recovery and none at all.

Practical Response

After a left-turn collision, the following steps place a claimant in the strongest evidentiary position:

• Call the police and secure a copy of the Police Crash Investigation Report (PCIR). Officer notes often anchor the initial fault picture.
• Preserve intersection surveillance video. Nearby businesses, gas stations, and municipal traffic cameras may hold decisive footage, but many systems overwrite within 7 to 30 days. A written preservation letter must be sent promptly.
• Identify eyewitnesses at the scene. Note plates, phone numbers, and short statements before witnesses disperse.
• Back up the dashcam file immediately from both vehicles if available.
• Photograph damage patterns. The location, angle, and depth of impact damage is critical to reconstructing the collision geometry.
• Request signal timing data from the municipality when the signal state is disputed.

Common Misunderstandings

• "I had a green light, so I had the right of way." A round green signal grants priority only to through and right-turning traffic. Left turners must still yield unless a green arrow is displayed.
• "Turning on yellow is allowed." A yellow signal instructs drivers to stop if it is safe to do so. Even a lawful entry on yellow does not eliminate the duty to yield to oncoming traffic.
• "The other driver was speeding, so I have no fault." Speeding increases the oncoming driver's share, but does not automatically discharge the left-turner's baseline duty to yield.
• "The insurer's initial decision is final." An insurance carrier's first fault assessment is only an opening position, and can be adjusted with rebuttal evidence.

Key Takeaways

• New Jersey left-turn collisions default to primary liability on the left-turning driver, but that presumption can be shifted with strong evidence of the oncoming driver's contributing fault.
• Under the 51% Rule, a plaintiff found 51% or more at fault recovers nothing. Between 1% and 50%, recovery is reduced proportionally.
• Speed of evidence preservation — video, signal timing, witnesses — often determines the fault outcome.
• An insurer's early fault call is not final. Rebuttal evidence and legal analysis can reset the negotiation.

FAQ

• If the other driver entered the intersection on yellow, does my fault percentage drop?

Yes, evidence that the oncoming driver ran a late yellow or red often shifts a significant share of fault away from the left turner. That said, the left-turner's duty to yield is not fully eliminated, and a share of comparative fault typically remains.

• What if I had a green arrow (protected left) when the collision occurred?

A green arrow grants priority to the left-turning driver. In that case, an oncoming vehicle that entered the intersection against the signal will usually carry the majority of liability.

• The other driver's insurer told me I am 100% at fault. What should I do?

Do not sign anything acknowledging fault, and avoid a recorded statement without counsel. Assemble the police report, video, and witness information, and submit a rebuttal. Initial fault findings are commonly revised once complete evidence is presented.

• What is the statute of limitations for a New Jersey left-turn accident lawsuit?

Generally two years from the date of the accident (N.J.S.A. 2A:14-2). Exceptions exist for minors and for claims against public entities, so early consultation is advisable.

• Is New Jersey's 51% rule the same as New York's rule?

No. New York uses Pure Comparative Negligence: a plaintiff who is 99% at fault can still recover the remaining 1%. For collisions with cross-border facts, the choice of forum can significantly change the outcome.
