California Intersections

California’s roadways are among the busiest and most traveled in the country. But they’re also some of the most hazardous, particularly at major intersections where dense traffic, high speeds, and mixed-use travel converge. Based on crash data from the California Highway Patrol’s SWITRS database, NHTSA’s Fatality Analysis Reporting System, and local Vision Zero initiatives, we’ve compiled a list of California’s top 10 deadliest intersections between 2017 and 2022.

1. Devonshire Street & Reseda Boulevard — Northridge, Los Angeles County

This intersection in the San Fernando Valley is a key connector between residential neighborhoods and major commercial centers. Reseda Boulevard, in particular, is a heavily trafficked north-south arterial, while Devonshire Street handles fast-moving east-west traffic.

The wide, multi-lane design and lack of adequate pedestrian refuge make it particularly hazardous. High-speed turns, distracted drivers, and frequent pedestrian crossings have resulted in multiple fatalities and serious injuries. Recent proposals from community leaders have called for speed limit reductions and additional crosswalk signals.

Residents in the area have long expressed concerns over unsafe conditions, with many calling for improved lighting and expanded sidewalks. Traffic volume during peak commuting also contributes to rear-end collisions and lane-weaving behavior. Schools, parks, and nearby businesses add to the pedestrian foot traffic.

2. Florence Avenue & Vermont Avenue — South Los Angeles

Situated in a densely populated corridor, this intersection experiences constant foot and vehicle traffic throughout the day. Florence and Vermont are both primary bus and commuting routes, and the area includes numerous shops, schools, and residential buildings.

Left-turn and angle collisions are prevalent due to limited protected turn phases and poor visibility caused by parked vehicles near the corners. Pedestrian injuries remain high due to inadequate crossing time. The community has pushed for better signage and high-visibility crosswalks.

City traffic planners have acknowledged the need for re-timed lights and reduced lane widths. Due to lane crowding, bicyclists are crowding and traveling through this intersection. Despite some targeted safety upgrades, serious crashes have remained stubbornly high.

3. Sepulveda Boulevard & Sherman Way — Van Nuys, Los Angeles County

This intersection sees a constant stream of buses, trucks, and personal vehicles. Mid-block pedestrian crossings, multiple bus stops, and nearby retail centers increase the risk for collisions.

Despite clear signage, speeding and last-second lane changes frequently contribute to rear-end and angle crashes. The intersection’s layout, spanning more than six lanes in each direction, creates visibility challenges for drivers making left turns.

Delivery trucks often block lines of sight, and cyclists navigate the area without bike infrastructure. School zones nearby raise concerns for children walking home in heavy traffic. Some traffic-calming proposals include speed bumps and protected bike lanes, but implementation has lagged.

4. Balboa Boulevard & Nordhoff Street — Northridge

This intersection is adjacent to California State University, Northridge, and serves a large student population. It combines high vehicle speeds with substantial foot traffic, particularly during school hours. Inadequate pedestrian signals and aggressive driving behaviors contribute to a high rate of pedestrian-related collisions.

Buses, delivery trucks, and student cyclists add complexity, leading to frequent right-turn and side-swipe incidents. Efforts have been made to introduce pedestrian-only signal phases, but congestion persists. Students report difficulty crossing, even with a walk signal, due to turning cars encroaching into the crosswalk.

Nighttime visibility is another issue, especially during the winter months. Crosswalk improvements and flashing beacons have been proposed to address these concerns.

5. 1st Street & Grand Avenue — Downtown Los Angeles

Located near cultural landmarks like Walt Disney Concert Hall and The Broad, this downtown intersection is a tourist and local traffic hub. Heavy bus volume, complex signal patterns, and multiple turning lanes make navigation difficult, especially for unfamiliar drivers. Given short crossing times and vehicles turning across crosswalks, pedestrians are particularly vulnerable here. Cyclists also face danger due to the lack of dedicated bike infrastructure. Sidewalk congestion and mid-block crossings by concertgoers add unpredictability to traffic patterns. Tour buses and large commercial vehicles navigating narrow turns can also block views. Recent Vision Zero initiatives have proposed adding curb extensions and high-visibility signals.

6. 5th Street & Market Street — San Francisco

This intersection sits at the heart of San Francisco’s bustling downtown. It features heavy pedestrian activity, nearby transit hubs, and dense commercial development. Many drivers and pedestrians alike rush to beat signals, increasing the risk of collision. Short signal timing and frequent jaywalking contribute to the danger. Efforts from SFMTA’s Vision Zero program have introduced some safety measures, but crash numbers remain high. Delivery trucks, bus shelters, and construction scaffolding also impact visibility. Pedestrian islands and extended curbs are being piloted to reduce conflict points. Bike messengers and rideshare pickups add to the chaos, particularly during lunch and evening rush hours.

7. 14th Street & Broadway — Oakland

This intersection, a central artery in downtown Oakland, supports high pedestrian, cyclist, and vehicle volumes. Government buildings, retail shops, and public transit stops surround it. Angle and broadside collisions often stem from vehicles running red lights or turning without yielding. Cyclists frequently report close calls due to narrow lanes and a lack of separation from motor traffic. The city has begun installing protected bike lanes and updating traffic signals, but improvements are still underway. Crowded sidewalks and frequent pedestrian crossings complicate traffic flow. Street vendors and transit delays further hinder visibility and reaction time for drivers.

8. El Camino Real (CA-82) & Ravenswood Avenue — Menlo Park

El Camino Real sees thousands of cars daily, a central commuter corridor on the San Francisco Peninsula. Multiple driveways, inconsistent signage, and limited pedestrian infrastructure complicate the intersection at Ravenswood Avenue. The area also sees a high volume of turning vehicles and distracted drivers. Nearby tech offices and residential zones create traffic surges during peak hours, exacerbating the crash rate. Residents have asked for better signal timing and improved lighting. Confusion at driveways and turn pockets increases the odds of side-impact collisions. Traffic calming plans include refuge islands, pedestrian countdown timers, and upgraded stoplights.

9. Florence Avenue & Figueroa Street — South Los Angeles

This intersection is a key access point for commuters and local residents. Its complex turn phases, high pedestrian activity, and limited corner visibility make it a hotspot for injury collisions. Red-light running and fast right-hand turns contribute significantly to the danger.

Crash numbers remain a concern despite recent improvements in signage and traffic signal upgrades. Street-level businesses and poorly lit sidewalks create further risks. School zones nearby add urgency to improvement efforts. Suggestions include curb extensions, crossing guards, and automated red-light cameras.

10. Ashby Avenue & San Pablo Avenue — Berkeley

A connector for local and regional travel, this intersection combines AC Transit routes, heavy car traffic, and foot and bike commuters. Narrow lanes, inconsistent road markings, and faded crosswalks make it difficult for drivers and pedestrians to navigate safely.

Berkeley’s dense layout and reliance on public transit add to the congestion. Side-swipe and pedestrian collisions are especially common. The city has discussed adding protected pedestrian waiting zones and updating signal systems. The lack of left-turn arrows causes driver hesitation and sudden stops. Cyclists must frequently merge with vehicles, increasing the risk of collision.

Safety Tips for Drivers and Pedestrians Near High-Risk Intersections

Even with improvements underway, drivers and pedestrians must remain vigilant, especially near the intersections listed in this guide. Here are some essential tips for staying safe:

For Drivers:

• Slow down as you approach busy intersections, especially those known for crashes.
• Avoid distractions like texting or adjusting the GPS while driving through high-traffic zones.
• Yield to pedestrians in all crosswalks, even with the green light.
• Use your turn signals in advance and watch for cyclists or pedestrians before turning.
• Come to a complete stop at red lights and stop signs; never rush a yellow light.
• Be cautious during peak hours or in school zones, as there may be sudden pedestrian crossings.

For Pedestrians:

• Cross only at marked crosswalks and wait for the walk signal when available.
• Make eye contact with drivers before entering the street to ensure they see you.
• Avoid jaywalking or crossing between parked cars; it’s difficult for drivers to see you.
• Wear visible or reflective clothing at night or during bad weather.
• Stay alert and avoid distractions like headphones or smartphones while crossing.

Whether on foot, behind the wheel, or riding a bike, taking a proactive approach to traffic safety can reduce your risk of injury and help save lives.
