What Are the Most Dangerous Intersections in the United States? (2025)

Every year, thousands of serious accidents happen at a handful of intersections. What are the most dangerous intersections in the United States for 2025?

The most dangerous intersections in the United States in 2025 are Lalor Street & SR-129 in Trenton, NJ, Route 7 & Hickory Road in Niskayuna, NY, and Roosevelt Boulevard in Philadelphia, PA, according to recent crash statistics.

With decades of experience helping crash victims nationwide, Mattiacci Law has reviewed the latest federal and state data to break down the deadliest hotspots and help drivers stay safer on American roads.

Key Findings: Worst Intersections in 2025

The 2025 data collected from the National Highway Traffic Safety Administration (NHTSA), state Departments of Transportation (DOTs), and local agencies highlights troubling patterns at specific intersections.

Here’s a detailed table of the Top 10 Most Dangerous Intersections in the U.S. for 2025:

Most Dangerous Intersections by State (2025)

The following table lists the most hazardous intersections across all 50 states, based on the latest available data. It includes the average number of accidents and fatalities per year at each location. Please note that data availability varies by state, and some figures are estimates based on historical trends.

Why Are These Intersections So Dangerous?

Intersections are the site of nearly 40% of all traffic collisions, according to the Federal Highway Administration (FHWA).

Several specific factors make the most dangerous intersections in 2025 especially hazardous:

Traffic Volume

Heavy traffic significantly increases collision risks.
Roosevelt Boulevard handles more than 90,000 vehicles daily, making it a hotspot for accidents involving pedestrians and drivers alike. Flamingo Road in Las Vegas also sees unusually high traffic levels, particularly due to tourist congestion.

More vehicles mean more opportunities for mistakes, delays, and miscalculations.

Poor Design or Visibility

Outdated designs and poor visibility contribute to accidents.
At Route 7 & Hickory Road in New York, inadequate pedestrian crossings and blocked sightlines have directly led to multiple fatal crashes.

Similarly, at intersections like Lalor Street & SR-129, poorly lit areas and faded lane markings increase driver confusion, especially at night.

According to a study by the Insurance Institute for Highway Safety (IIHS), intersections without protected left-turn signals see 20% higher crash rates than those with better design (IIHS).

Driver Behavior Factors

Negligence remains a leading cause.
Speeding, running red lights, distracted driving, and driving under the influence all escalate the danger at busy intersections.

NHTSA’s Fatality Analysis Reporting System shows that 22% of intersection fatalities involve speeding, while another 12% involve distracted driving (NHTSA FARS).

Real Accident Examples: 2024–2025

• Trenton, NJ (Lalor St & SR-129): A three-car pileup in January 2025 resulted in two deaths when a speeding driver ran a red light during icy conditions (New Jersey DOT Crash Report).
• Niskayuna, NY (Route 7 & Hickory Rd): In late 2024, a pedestrian was killed trying to cross at dusk without a dedicated signal, leading to calls for immediate intersection redesign.
• Roosevelt Boulevard, Philadelphia: Despite multiple speed camera installations, pedestrian fatalities have persisted. One fatal crash in March 2025 involved a hit-and-run where the victim was legally crossing in a marked crosswalk.

Year-over-Year Comparison (2024 vs 2025)

Analyzing crash statistics between 2024 and 2025 shows that despite improvements at some locations, several intersections became even deadlier:

Trends Observed:

• Tourist-heavy areas like Las Vegas saw significant accident increases.
• High-speed corridors (e.g., Roosevelt Blvd) continue to experience persistent fatality rates despite speed reduction efforts.
• Pedestrian accident rates rose sharply, especially at poorly marked crosswalks.

Solutions Cities Are Trying

Facing stubbornly high crash rates, many cities are deploying aggressive solutions in 2025:

• Vision Zero Initiatives: Cities like Philadelphia and Las Vegas are expanding Vision Zero programs aiming for zero traffic deaths by redesigning dangerous roads (Vision Zero Network).
• Protected Intersections: New layouts protect pedestrians and cyclists through physical separation.
• Dedicated Left-Turn Signals: Reducing crashes by installing dedicated left-turn lanes and protected arrows.
• Improved Signage and Lighting: Installing brighter LED traffic lights, flashing pedestrian signals, and better-lit crosswalks.
• Red-Light Cameras: Over 150 new camera systems are being installed nationwide to reduce red-light running fatalities.
• Speed Reduction Zones: Urban areas are lowering speed limits at major intersections, cutting average speeds by up to 20% (FHWA Traffic Calming Guide).

These solutions show promise but require sustained investment and community support to yield long-term safety improvements.

According to FHWA, intersections with modern roundabouts reduce injury crashes by approximately 75% compared to traditional intersections.

Tips for Staying Safe at Dangerous Intersections

• Slow Down Early: Approach intersections with extra caution.
• Stay Focused: Minimize distractions like cell phones, even at red lights.
• Anticipate Others’ Mistakes: Assume nearby drivers may make sudden moves.
• Avoid Risky Turns: Left turns across traffic are particularly dangerous — wait for protected arrows when possible.
• Yield to Pedestrians: Always check crosswalks and allow pedestrians to cross safely.

Sources and Methodology

The information presented here draws from official government and transportation safety data:

• NHTSA Fatality Analysis Reporting System (FARS)
• Federal Highway Administration (FHWA)
• Insurance Institute for Highway Safety (IIHS)
• State Department of Transportation (DOT) crash reports for NJ, NY, PA, NV, MI, and FL

Data from early 2025 were compiled with preliminary public datasets, ensuring accuracy to the best extent available at the time of publication.

What 2025 Data Tells Us About Road Safety

The 2025 analysis reveals an unsettling truth: America’s most dangerous intersections are not improving fast enough. Increases in fatal crashes at already high-risk spots like Roosevelt Boulevard and Route 7 & Hickory Road should concern every driver.
