San Diego County’s Highest-Crash Roads in 2024
The highest-crash intersection in this San Diego County dataset in 2024 was I-805 southbound at Imperial Avenue, which recorded 19 crashes and 9 injuries. The highest-crash freeway segment was I-805 southbound, with 147 crashes, 91 injuries, and 1 fatality. Both locations sit along the I-805 corridor, a major north-south route connecting the South Bay to central San Diego County.
These rankings are based on 2024 crash records from the California Crash Reporting System (CCRS), published by the California Highway Patrol through California Open Data. The dataset was accessed on June 27, 2026. CCRS is updated periodically, so that counts may change in future releases.
What These Rankings Measure
This ranking measures crash concentration — the total number of reported collisions at a specific location during 2024. It is not a formal safety rating issued by a government agency, and is not an exposure-adjusted crash rate that accounts for traffic volume. These rankings cover San Diego County, which includes 18 incorporated cities and unincorporated areas, and identify the locations where reported crashes happened most often in 2024. They do not replace an engineering safety study or official traffic impact analysis.
San Diego County’s Highest-Crash Intersections in 2024
Based on 2024 CCRS data, these five locations recorded the highest crash totals in this San Diego County dataset:
| Intersection | Crashes | Injuries | Fatalities | Key factor |
|---|---|---|---|---|
| I-805 S/B at Imperial Avenue | 19 | 9 | 0 | This is a high-volume interchange near the South Bay gateway. Merging traffic and commercial access points creates constant lane-change conflicts. |
| I-805 S/B at Chula Vista City Limit | 16 | 8 | 0 | This location marks the transition between San Diego and Chula Vista. Speed differentials and ramp geometry increase crash risk at this boundary. |
| I-8 E/B at College Avenue | 15 | 7 | 0 | This intersection serves San Diego State University and residential areas east of Mission Valley. Heavy student and commuter traffic peaks during class hours. |
| SR-94 E/B at I-805 | 14 | 6 | 0 | This is a complex interchange where SR-94 and I-805 converge. Multiple merge points and weave sections compress driver decision time. |
| I-5 S/B at National City Blvd | 13 | 5 | 0 | This interchange serves as a gateway to National City near the port corridor. Commercial truck traffic and frequent lane changes near terminal access roads create conflict points. |
Each of these intersections involves a freeway interchange or major transition point where traffic speeds, volumes, and vehicle types converge. The common thread is compressed decision time — drivers must judge merge gaps, signal timing, and cross-traffic simultaneously.
San Diego County’s Highest-Crash Freeway Segments in 2024
San Diego County’s freeway network carries substantial commuter, military, port, and cross-border traffic. The five highest-crash freeway segments in 2024 were:
| Freeway segment | Crashes | Injuries | Fatalities | Local context |
|---|---|---|---|---|
| I-805 Southbound | 147 | 91 | 1 | This segment runs through Chula Vista and National City toward the South Bay. It passes near Sweetwater High School and major residential corridors. |
| I-5 Southbound | 132 | 74 | 2 | This corridor connects downtown San Diego to the US-Mexico border at San Ysidro. Heavy truck and passenger traffic near the border crossing creates unpredictable speed patterns. |
| I-805 Northbound | 128 | 79 | 0 | This route mirrors the southbound pattern and serves the South Bay-to-city commute corridor with multiple high-density residential off-ramps. |
| I-8 Eastbound | 97 | 53 | 1 | This corridor links Mission Valley to East County and passes near San Diego State University and active commercial corridors. |
| SR-94 Eastbound | 84 | 47 | 0 | This segment runs through southeastern San Diego neighborhoods toward Spring Valley. It serves the Boone Elementary School area and Bell Middle School near Briarwood Road. |
I-805 accounts for the two highest-crash freeway segments in this San Diego County dataset — a combined 275 crashes, 170 injuries, and 1 fatality in 2024. That concentration reflects the I-805 corridor’s role as a major South Bay-to-city commute route through San Diego County.
What San Diego County’s High-Crash Roads Have in Common
These patterns are reflected across San Diego County’s five highest-crash intersections and freeway segments:
I-805 corridor concentration. Both the top intersection and two of the top five freeway segments are on I-805. The South Bay-to-city commute creates sustained high-volume conditions through multiple interchange zones with complex geometry.
Border and port traffic mix. I-5 southbound carries cross-border traffic near San Ysidro. Passenger vehicles, commercial trucks, and border-wait traffic can create unpredictable speed patterns.
Military installation proximity. Some San Diego County freeway corridors also serve military, port, commuter, and cross-border traffic, which can change traffic patterns by time of day.
University and school-zone traffic. I-8 eastbound passes near San Diego State University. SR-94 eastbound serves neighborhoods near Boone Elementary School and Bell Middle School near Briarwood Road. These corridors may see heavier traffic during school hours and campus events.
Merge and weave zone complexity. All five top intersections involve interchange ramps or multi-directional merge points. Where SR-94 meets I-805, drivers must navigate overlapping weave sections with limited sight distance and high-speed differentials.
Who May Have the Crash Report or Evidence?
After a crash on one of San Diego County’s high-crash roads, the crash report and relevant evidence may be held by different agencies, depending on where the crash happened:
| Crash location | Likely agency or custodian | What to request |
|---|---|---|
| Freeway crash on I-805, I-5, I-8, or SR-94 | California Highway Patrol — San Diego Area (Border Division) | CHP crash report (CHP 190 request process), CAD/dispatch records, and dashcam or body-worn camera footage if available |
| San Diego city street crash | San Diego Police Department | Collision report, CAD/dispatch records, and available surveillance footage |
| Crash involving a road condition, signal, or signage issue | City of San Diego, County of San Diego, or Caltrans, depending on who controls the roadway | Signal timing records, maintenance logs, prior complaints, work orders, and inspection history |
| Crash involving a city or government vehicle | City of San Diego Risk Management or State of California | Incident report, vehicle maintenance records, and driver assignment records |
| Medical treatment after the crash | Hospital, urgent care, or medical provider | Emergency records, imaging, discharge instructions, itemized bills, and treatment notes |
For crashes on I-805, I-5, I-8, or SR-94, the California Highway Patrol — San Diego Area (Border Division) generally takes the report. For crashes on San Diego city streets, the San Diego Police Department generally handles the report. The correct agency depends on the exact crash location, not the nearest street name.
What To Do After a Crash at One of These San Diego Locations
Your health and legal options depend on what you do in the first hours after a crash. On a busy San Diego freeway or intersection, the scene itself is your evidence.
- Call 911. Report the crash immediately if anyone is injured or the scene is unsafe. A CHP or SDPD report creates the official record. For non-emergency situations on city streets, the San Diego Police Department’s non-emergency line is (619) 531-2000.
- Document the scene before moving vehicles. Photograph vehicles, road conditions, traffic signals, skid marks, debris, and visible injuries. Note the exact location and the direction each vehicle was traveling.
- Exchange information. Ask the other driver for their name, phone number, insurance carrier, and policy number.
- Collect witness information. Ask anyone who saw the crash for their name and phone number before they leave. Witness accounts matter most when drivers disagree on what happened.
- Seek medical care the same day. Some injuries do not produce immediate symptoms. A same-day evaluation creates a medical record and can matter for your claim.
- Contact an attorney before speaking to the other driver’s insurer. An early recorded statement can affect your claim before you know the full extent of your injuries.
How Liability Works After a San Diego Intersection or Freeway Crash
Liability in a San Diego crash depends on the specific facts of the collision — driver conduct, road conditions, traffic controls, and witness observations.
Driver negligence. Speeding, distracted driving, unsafe lane changes, and failure to yield are the most common causes of crashes at high-crash intersections. Evidence includes the police report, witness statements, dashcam or surveillance footage, and cell phone records.
Government entity liability. If a defective road condition, a failed signal, inadequate signage, or an unaddressed hazard contributed to the crash, a public entity may bear responsibility. A claim against a California public entity requires a written government claim filed within six months of the incident under the California Government Claims Act.
Commercial vehicle liability. Crashes involving port trucks, military vehicles, or delivery vehicles on I-5 and I-805 may involve multiple defendants — the driver, employer, carrier, and maintenance contractor. Federal FMCSA regulations may also apply to commercial carriers.
Comparative fault. California uses pure comparative negligence. Even if you were partly at fault, you may still recover damages reduced by your percentage of fault.
Filing Deadlines for San Diego Crash Claims
Missing a deadline can bar your claim entirely. Two deadlines matter most:
Two-year deadline for personal injury lawsuits. California Code of Civil Procedure §335.1 gives most injury victims two years from the date of the crash to file suit.
Six-month deadline for government claims. If a public entity contributed to the crash through a road defect or a government vehicle, a written administrative claim must be filed within six months. A claimant must file this before filing a lawsuit against a public entity. Missing this deadline can bar the government-related claim entirely.
These deadlines are separate. A government claim deadline can pass while the general lawsuit deadline is still open. Both must be tracked independently.

FAQs About San Diego County’s Most Dangerous Intersections and Crash Claims
Who handles the crash report on I-805 or I-5 in San Diego?
The California Highway Patrol — San Diego Area (Border Division) generally handles crash reports on I-805, I-5, I-8, and SR-94 within San Diego County. For crashes on city streets, the San Diego Police Department generally takes the report. A DMV SR-1 may also be required within 10 days if anyone was injured or killed, or if property damage exceeded $1,000. The SR-1 is separate from any CHP, police, or insurance report.
What if a road defect or signal failure contributed to my crash on a San Diego freeway?
If a road condition, a failed traffic signal, or inadequate signage contributed to your crash, you may have a claim against the government entity responsible for maintaining that road. Claims against public entities in California require a written government claim to be filed with the responsible agency within 6 months of the incident. The agency may be the City of San Diego, Caltrans, or the County of San Diego, depending on which entity controls the road where the crash occurred.
Will the crash history at I-805 or I-8 help my injury claim?
Not automatically. Crash history does not prove that any individual driver was negligent in your specific collision. It may support requests for signal records, maintenance history, or public-entity notice arguments if a road condition contributed. The driver’s fault still depends on the facts of your crash.
What court handles a San Diego car accident lawsuit?
Most San Diego car accident cases are resolved through settlement before any lawsuit is filed. If a lawsuit becomes necessary, civil personal injury cases in San Diego County are generally filed in the Superior Court of California, County of San Diego. Civil unlimited matters are handled at the Hall of Justice at 330 W. Broadway in downtown San Diego. Venue and filing requirements should be verified before filing.
What if the other driver on I-5 near the border had no insurance?
Your own uninsured motorist (UM) coverage may apply. California insurers are required to offer UM coverage, but drivers may waive it in writing. Check your policy to confirm whether you elected UM coverage. Cross-border crashes near San Ysidro may involve additional insurance and jurisdiction complexities — an attorney can help you identify all available coverage sources.
