It’s critical to know the local traffic regulations anytime you’re behind the wheel. Because there’s an unusual one in the Garden State, many drivers will ask: What is the New Jersey left lane law?

New Jersey’s left lane law, often called the “keep right” law, designates the left lane for passing only. Drivers must use the right lane unless actively overtaking another vehicle or preparing for a left turn. Failing to keep right can result in fines and points on your license.

In addition, not complying with the left lane law also increases the potential for accidents. If you were involved in a crash, your top priority should be retaining skilled legal representation. Over decades practicing as a New Jersey car accident attorney, I’ve helped many injured victims and their families get their lives back after tragedy strikes. I’m happy to assist with your legal remedies, but some background information is also helpful.

 

What is the Lane Change Law in New Jersey?

New Jersey law requires drivers to signal and ensure their intended lane change is safe before moving. Under New Jersey Statute 39:4-88, drivers must remain within a single lane unless they have a clear reason to change. Abrupt or unsafe lane changes can lead to fines or penalties. This regulation is designed to prevent sudden movements that could endanger other road users.

Drivers should check mirrors and blind spots, giving ample warning to others on the road. Failure to comply with the law increases the potential for injury-causing and fatal auto accidents.

 

Left turn law in New Jersey aims to ease traffic congestion.

 

How Do New Jersey’s Left Lane Rules Work?

New Jersey enforces strict left-lane driving laws to support smoother traffic flow. Drivers should use the left lane primarily for passing. Remaining in the left lane unnecessarily, especially when slower than surrounding traffic, may result in a citation. These rules aim to:

  • Reduce congestion
  • Prevent road rage incidents
  • Enhance fuel economy by smoothing traffic flow
  • Improves highway safety and efficiency

Motorists must return to the right or middle lane after overtaking unless preparing for a left turn. Remaining in the left lane too long after making a maneuver could also lead to a violation of the law.

 

What is a Left Lane Violation?

A left lane violation occurs when a driver uses the left lane improperly. In New Jersey, staying in the left lane without actively passing or turning left violates NJSA 39:4-88. This offense can lead to:

  • Fines ranging from $50 to $200
  • Potential points on a driver’s record
  • A license suspension, when points accrue

Such violations also increase the risk of traffic congestion and accidents. Drivers should use the left lane responsibly to avoid penalties and promote safety.

 

What is Violation 39:4-88 in NJ?

Violation 39:4-88 is a term that refers to breaking the law on left lane changes, and it governs improper use of traffic lanes in New Jersey. It requires drivers to stay in their designated lane and prohibits left-lane hogging. Offenders may face monetary fines and points on their driving record.

The law also addresses reckless lane usage, such as weaving between lanes without justification. By adhering to this statute, drivers help maintain a safer and more orderly traffic system. Proper lane discipline reduces collisions and legal repercussions.

 

How Does NJ 39:4-123 Affect Motorists?

New Jersey Statute 39:4-123 regulates turns and lane changes at intersections. Drivers must signal their intentions clearly and execute turns only from designated lanes. For example, left turns must originate from the leftmost lane unless otherwise marked.

This statute promotes predictability, allowing other road users to anticipate movements and react appropriately. Violations, such as improper signaling or turning from the wrong lane, can lead to accidents or traffic citations.

Does New Jersey’s Left Lane Law Disrupt Traffic Flow?

Contrary to popular misconceptions, New Jersey’s left lane law improves traffic flow. By mandating that drivers use the left lane solely for passing, highways operate more efficiently. Motorists and truck drivers traveling at different speeds can safely coexist without unnecessary blockages.

Adhering to these regulations enables smoother and safer journeys for all road users. However, noncompliance with this rule, such as lingering in the left lane, disrupts traffic and causes frustration. With impacts on traffic from offending motorists, there is also an increased risk of auto collisions.

 

What is a Jughandle in NJ?

A jughandle is a unique traffic design used extensively on busy New Jersey highways to manage left turns. Instead of turning left directly at an intersection, drivers must use a dedicated loop or ramp to approach the road they wish to join.

Jughandles are primarily used on state and local highways with high traffic volumes, including the Garden State Parkway, Atlantic City Expressway, and New Jersey Turnpike. By redirecting left turns and U-turns to a designated exit or ramp on the right side of the road, jughandles reduce the risk of collisions and congestion at busy intersections.

However, understanding and adhering to jughandle signs are crucial for safe driving in New Jersey. Crashes are more likely when drivers don’t know how jughandles work, particularly when approaching high-traffic areas.

 

Victims of car accidents have legal options for seeking compensation.

 

How Does New Jersey’s Left Lane Law Affect Traffic Accidents?

New Jersey’s left lane law significantly impacts accident rates. By minimizing left-lane misuse, the regulation reduces collisions caused by tailgating, road rage, and sudden lane changes. Drivers traveling at consistent speeds in the appropriate lanes encounter fewer hazardous interactions.

However, noncompliance—such as lingering in the left lane—can create dangerous bottlenecks, increasing the likelihood of rear-end and sideswipe crashes. Compliance with this law enhances overall road safety.

In terms of a victim’s rights in the presence of a left lane violation, the failure to comply could stand as powerful evidence of negligence. When you’ve been hurt in a car accident, you will need to prove that the other motorist breached the duty to drive safely. Not safely maneuvering through a jughandle demonstrates negligence.

 

Do Victims Have Rights to Seek Compensation After an Auto Crash?

Victims injured in car accidents due to another driver’s negligence have the right to pursue compensation under New Jersey law. This may include:

  • Medical bills
  • Lost wages
  • Pain and suffering
  • Emotional distress

Establishing fault is crucial in cases like car accidents that are based upon the theory of negligence. These claims often require evidence like police reports, witness statements, or traffic camera footage. Consulting an experienced attorney can help victims understand their rights and seek appropriate legal remedies to recover damages.

 

What Should I Do After a Car Accident in New Jersey?

The aftermath of a crash can be chaotic, so it’s important to use a few tips to get through the experience. After a car accident in New Jersey:

  • Prioritize safety by pulling your vehicle to the shoulder.
  • Seek medical attention right away for yourself or other injured victims.
  • Report the incident to law enforcement.
  • Obtain the police report, which may be vital for insurance claims or legal action.
  • Exchange contact and insurance information with other parties involved.
  • Document the scene with photos and video.
  • Gather witness statements, if possible.
  • Consult a legal professional as soon as your injuries are stabilized.

An attorney will help you understand your rights and will guide you with the necessary steps to protect your interests after an accident. The next stages of the legal process involve filing an insurance claim and suing the at-fault driver in court, so legal help is crucial.

FAQs About the Left Lane Law in New Jersey

Is it illegal to drive in the left lane in every state?

No, it's not universally illegal to drive in the left lane. While many states have "keep right" laws, they typically include exceptions. The left lane is generally intended for passing slower vehicles, making left turns, or when traffic conditions necessitate its use.

Some states explicitly prohibit continuous driving in the left lane except under specific circumstances. Therefore, it's not illegal everywhere, but its use is often restricted.

How much is the fine for driving in the left lane?

In New Jersey, the fine for violating the "keep right" law, which includes improper use of the left lane, can range from $100 to $300. This applies when drivers fail to move from the left lane after passing another vehicle or when driving in the right lane is not impractical.

Additionally, there's a $50 surcharge added to these tickets to fund road signs educating drivers about the "keep right" law. This means the total cost could be between $150 and $350, along with two points on your driving record.

What are two laws that you must obey on the NJ roadway?

Two crucial laws in New Jersey are the "keep right" law and yielding to emergency vehicles. The "keep right" law mandates that drivers use the right lane unless passing, while the left lane is primarily for passing.

Also, New Jersey law requires drivers to yield the right-of-way to emergency vehicles displaying flashing lights and sirens. Failure to comply with either of these laws can result in fines and points on your license.

What is the left turn law in New Jersey?

New Jersey's left-turn law requires drivers to yield to oncoming traffic when making a left turn at an intersection, unless a traffic signal gives them the right-of-way (a green left-turn arrow). This means you must assess oncoming traffic and only proceed with the turn when it's safe to do so. Failure to yield can result in accidents and traffic violations. This applies to both controlled intersections (with signals) and uncontrolled intersections (without signals).

What is the New Jersey left turn law for roads with three or more lanes?

The New Jersey left turn law requires drivers to make left turns from the center lane or lane closest to the centerline, unless signs or signals direct otherwise. When turning left, drivers must yield to oncoming traffic and ensure the turn can be made safely.

Additionally, if there are designated left-turn lanes or arrows, drivers should use those lanes. Proper signaling is required at least 100 feet before the turn to alert other drivers. Always obey posted signs or pavement markings.
