Year-over-year records

How reported SR-118 crashes compare by year

Annual counts use the same road-matching method as this profile. The latest year may be incomplete if the source data has not reached year end.

2021 to 2026
Bars show reported crash-record counts, not risk rates or traffic-volume-adjusted danger.

Sideswipe Context

Of the sideswipes with clear lane details, 180 crossed multiple reported lanes (lane-departure context), while 30 occurred within a single lane.

Note: Lane numbers are officer-reported (e.g. "Lane 1" is typically the fast lane). They are useful for local review but do not reflect verified road geometry.

Methodology

How this corridor profile is produced

No applied canonical mapping exists for SR-118 yet, so this profile temporarily uses the legacy curated alias matcher against the officer-recorded primary-road label. The reporting window is 2025-10-23 through 2026-10-22. Source records come from the California Highway Patrol California Crash Reporting System.

Limitations

What the numbers cannot establish

  • Raw crash counts do not measure individual risk or identify the “most dangerous” segment.
  • Traffic volume, vehicle miles traveled, road length, construction, and enforcement exposure are not controlled here.
  • Road and city labels can be incomplete, inconsistent, or revised after publication.
