How Does Road Infrastructure Affect Traffic Accidents in California

Key Takeaways

• Understand how road infrastructure impacts traffic safety

Poorly designed intersections, inadequate lanes, and insufficient signage increase traffic accident risks for everyone.

• Spot high-risk urban areas in LA and SF

Downtown streets, complex intersections, and high-traffic corridors create environments where accidents are more likely to occur.

• Recognize how infrastructure gaps affect vulnerable road users

Missing crosswalks, narrow bike lanes, and uneven pavement disproportionately endanger pedestrians and riders navigating city streets.

• Work with an experienced pedestrian or rider accident lawyer

RMD Law can review road conditions, gather evidence, and help you pursue full compensation if you were in an accident due to unsafe streets.

How Does Road Infrastructure Affect Traffic Accidents in California

California’s roads rank among the most dangerous in the United States, especially for pedestrians and cyclists. From 2022 to 2024, Los Angeles recorded an average of 160 pedestrian fatalities, while San Francisco saw 21.3 annually—numbers that reflect more than traffic volume. They point to a system under strain. 

As drivers, cyclists, and pedestrians compete for the same limited space, public attention and legal scrutiny on road infrastructure safety have increased. Poorly designed intersections, inadequate bike lanes, and uneven pavement often intersect with human error, magnifying the risk of severe collisions. 

This article explores how road infrastructures can contribute to traffic accidents in California. It also explains how a pedestrian or rider accident lawyer can help you seek accountability and compensation.

How Road Infrastructures Affect Traffic Accidents in California

California streets don’t just carry vehicles—they carry risk. Every lane, intersection, and crosswalk shapes how safely you move through the city. These risks multiply in urban hubs like Los Angeles and San Francisco. Here’s how:

1. Poor road design and layout

Confusing intersections, unclear lane merges, and inadequate turning lanes increase the likelihood of collisions. 

In Los Angeles, Sunset Boulevard has long been flagged for accidents caused by multiple merging lanes and poorly timed traffic signals. Hollywood Freeway off-ramps also see high crash rates during peak hours, when congestion magnifies design flaws. 

Meanwhile, complex intersections along Market Street and Van Ness Avenue in San Francisco challenge both drivers and pedestrians, increasing the likelihood of collisions.

2. Inadequate pedestrian and cyclist infrastructure

A missing crosswalk or unprotected bike lane can become a deadly oversight. Downtown LA and Venice Boulevard often see high pedestrian traffic but limited safety measures, which raises injury risk. 

San Francisco’s Mission Street struggles with similar gaps, including narrow bike lanes and unpredictable vehicle patterns, which contribute to collisions. 

3. Road surface conditions and maintenance issues

Potholes, uneven pavement, faded lane markings, and poor drainage inconvenience drivers and cause accidents. LA and SF municipal maintenance reports identify high-traffic areas where deferred upkeep correlates with repeated crashes. 

Vehicles swerve, brakes fail, and cyclists lose control—neglected surfaces turn into direct hazards. Regular maintenance reduces these preventable incidents and keeps streets safer for everyone.

4. Insufficient lighting and visibility

Nighttime or dimly lit streets hide hazards. In parts of Los Angeles, dark alleyways limit visibility and leave little time to react. In San Francisco’s Outer Sunset District, weak lighting and blocked signs make it harder for all road users to judge traffic and avoid collisions. 

When people can’t see clearly, crashes become more severe. Better lighting and clear signs make a real difference.

5. Construction zones and temporary road changes

Abrupt detours, poorly marked work zones, and unclear signs in construction sites temporarily spike traffic accidents. Following California’s work-zone safety rules helps, but you still need to stay alert. Authorities also have a responsibility to provide clear signs and guidance. When either side fails, crashes can happen, and injuries can be severe.

How a Pedestrian or Rider Accident Lawyer Can Help

When unsafe streets cause injuries, navigating the aftermath can feel overwhelming. A pedestrian or rider accident lawyer can turn complex liability into clear, actionable steps. 

In cities like Los Angeles and San Francisco, where road infrastructure issues are common, legal expertise becomes crucial.

1. Identify infrastructure-related liability

Lawyers determine whether a city, county, or state agency shares responsibility for your accident. They distinguish between driver negligence and government liability, assessing reports, maintenance records, and design flaws. 

In Downtown LA or SF’s Financial District, attorneys can pinpoint whether intersections, crosswalks, or bike lanes contributed to your injury. It’s crucial to know who’s accountable to help you build a stronger claim.

2. Navigate government claims and deadlines

California law requires filing claims against city or state entities within strict timelines. Missing these deadlines can bar your right to compensation. An experienced attorney can make sure that you meet all filing requirements for roads maintained by LA Metro, SF Municipal Transportation, or other local agencies. Acting quickly preserves your options.

3. Gather evidence linked to road conditions

Attorneys collect crash reports, traffic camera footage, maintenance logs, and expert evaluations. Documenting potholes or obstructed signage can create a clear link between road infrastructure defects and your accident. Proper evidence increases your chances of full recovery.

4. Maximize compensation for long-term impact

Legal counsel evaluates medical expenses, lost wages, rehabilitation, and long-term disability. They help victims secure compensation that reflects the full scope of injury, addressing both immediate and lasting consequences.

Your Safety, Your Rights

Urban streets in Los Angeles and San Francisco pose unique hazards. Poor design, deferred maintenance, limited visibility, and construction zones all contribute to higher traffic accidents, especially for pedestrians and riders. These environments demand extra caution, but even the most careful individuals can suffer serious injuries.
