San Diego's Most Dangerous Roads

San Diego's most dangerous surface streets

Across the five years from 2021 through 2025, a small group of city streets accounted for an outsized share of the people killed or seriously injured on San Diego's roads. Ranked by the total number of people killed or seriously injured, these were the ten most dangerous surface streets in the city:

1. El Cajon Boulevard: 35 people killed or seriously injured (5 deaths, 30 serious injuries)
2. Market Street: 26 (3 deaths, 23 serious injuries)
3. Genesee Avenue: 24 (5 deaths, 19 serious injuries)
4. Imperial Avenue: 23 (6 deaths, 17 serious injuries)
5. Mission Boulevard: 22 (5 deaths, 17 serious injuries)
6. University Avenue: 19 (2 deaths, 17 serious injuries)
7. Rosecrans Street: 17 (5 deaths, 12 serious injuries)
8. Fairmount Avenue: 17 (0 deaths, 17 serious injuries)
9. Mira Mesa Boulevard: 16 (6 deaths, 10 serious injuries)
10. Balboa Avenue: 15 (3 deaths, 12 serious injuries)

El Cajon Boulevard sits at the top, and the corridors just behind it (Market Street, Genesee Avenue, and University and Imperial Avenues) share a profile: long, straight, multi-lane arterials that move heavy traffic at high speed through dense, walkable neighborhoods. These are roads built to move cars quickly that also carry people walking, biking, and turning in and out of homes and businesses. That mix, at speed, is what produces the most serious collisions.

One caution about reading this list. These are raw totals, not rates. Long, busy arterials naturally see more people hurt simply because more people drive, walk, and bike on them, so the ranking shows where the most people are injured rather than the highest risk per trip. For a population-adjusted comparison of how San Diego comes out against similarly sized California cities, the California Office of Traffic Safety crash rankings weight the numbers by population and miles traveled. Crash data is also revised as reports are finalized, and the city's ranking shifts year to year, so the live Vision Zero dashboard is the best place to check the current picture for a specific street.

San Diego's deadliest freeways

The freeways that run through San Diego carry the highest absolute numbers of all. Over the same 2021 through 2025 period, ranked by people killed or seriously injured in both directions combined:

1. Interstate 5: 351 people killed or seriously injured (76 deaths, 275 serious injuries)
2. Interstate 805: 226 (42 deaths, 184 serious injuries)
3. Interstate 15: 158 (24 deaths, 134 serious injuries)
4. Interstate 8: 148 (29 deaths, 119 serious injuries)
5. State Route 94: 88 (27 deaths, 61 serious injuries)
6. State Route 163: 82 (13 deaths, 69 serious injuries)

These are state highways, maintained by Caltrans rather than the city. That distinction matters if a road defect, missing barrier, or dangerous design contributed to a freeway crash, because the claim runs against a different agency on the same short deadline. We cover that path in our guide to whether you can sue Caltrans.

How San Diego tracks its most dangerous roads

In 2015 the city adopted Vision Zero, a long-term goal of eliminating traffic deaths and severe injuries. A core idea behind it is "systemic safety": rather than waiting for a body count at one corner, the city studies crash patterns across the whole network to find the streets and features that produce the worst outcomes.

The program is data-driven, built on San Diego Police Department crash reports. The city publishes that information through its Vision Zero program, and its public crash dashboard lets anyone filter collisions by year, location, and travel mode. Those same police reports feed the Statewide Integrated Traffic Records System (SWITRS), the California Highway Patrol's master crash database, which UC Berkeley maps and makes searchable through its Transportation Injury Mapping System (TIMS). The corridor figures above come from that SWITRS data for collisions inside the City of San Diego.

What makes these roads dangerous

Severe crashes on these corridors usually trace back to a few road features working together:

• High speed. Higher speeds leave less time to react and make every crash more violent, which is why the city has worked to lower limits on many corridors.
• Wide, multi-lane crossings. The more lanes a person has to cross, the more exposure to traffic and the more chances for a driver to miss them.
• Uncontrolled crossings on fast roads. A crossing placed across a high-speed, multi-lane arterial without a signal or other protection invites the most dangerous conflicts.
• Turning conflicts. Left turns across oncoming traffic and turns across crosswalks are among the most common severe-crash patterns.
• Long blocks and limited lighting that concentrate crossings in risky spots and reduce visibility after dark.

These same features drive the road-defect and intersection cases we handle, including road hazards that injure cyclists and crashes at the city's most dangerous pedestrian intersections.

​

When the road itself creates liability

When a public agency knows a road or intersection is dangerous and fails to fix it, that agency can be liable for a resulting crash. That is a separate path to recovery from a claim against the driver, and it often reaches deeper resources. We explain how it works for a specific defect in our guide to who is liable for a dangerous San Diego road.

Proving it takes evidence the agency keeps and the road itself shows: prior complaints, earlier crashes at the same spot, traffic studies, and the physical conditions at the scene. Much of that evidence is time-sensitive, so the investigation has to start early.

​

What to do if you were hurt on one of these roads

Get medical care, then make sure the crash is documented and investigated before the scene changes. The most important deadline to know is this: if a government agency shares the blame for a dangerous road, you must usually file a formal claim with that agency within six months of the crash, not the two years that applies to an ordinary injury claim. Because you cannot always tell at the scene whether the road was a cause, it is worth having a serious crash reviewed early. A dangerous roadway conditions lawyer can sort out who is responsible and protect the short deadline.
