Compare the same measure across two years
This brief uses the 2022 OTS table and 2023 OTS table for Los Angeles. Source pages checked September 25, 2026. It is a historical snapshot, not live reporting.
| Measure | 2022 | 2023 | Change |
|---|---|---|---|
| All collision categories | 8,944 | 8,116 | -828 (-9.3%) |
| Alcohol-involved collisions | 1,676 | 1,508 | -168 (-10.0%) |
| Motorcycle-involved collisions | 605 | 553 | -52 (-8.6%) |
| Pedestrian-involved collisions | 1,524 | 1,432 | -92 (-6.0%) |
| Bicyclist-involved collisions | 475 | 393 | -82 (-17.3%) |
| Measure | 2022 | 2023 | Change |
|---|---|---|---|
| Speed-related fatal or injury collisions | 1,224 | 1,104 | -120 (-9.8%) |
| Nighttime fatal or injury collisions (9:00 p.m. to 2:59 a.m.) | 1,649 | 1,498 | -151 (-9.2%) |
| Hit-and-run fatal or injury collisions | 2,701 | 2,549 | -152 (-5.6%) |
Change = 2023 minus 2022. Percentage change uses the 2022 count as its denominator and is rounded to one decimal place.
What stands out in Los Angeles
All eight selected measures declined between these two years. The hit-and-run collision count fell from 2,701 to 2,549, a decrease of 152 (5.6%). That reduction was smaller proportionally than the change in the overall victim count, but the two measures have different units and must not be combined.
For Los Angeles readers, the city label matters. This table does not represent Los Angeles County, neighboring cities, or every freeway crash within city boundaries. It cannot identify a dangerous intersection or explain conditions on a particular commute. Those questions require records with locations and a matching reporting scope.

Read the limits with the numbers
The OTS methodology draws on SWITRS police-reported data. Victim measures combine people killed and injured; one collision can affect several people. The second table counts collisions. Property-damage-only events are excluded, and categories can overlap.
City coverage excludes CHP reports on roads with shared jurisdiction. These are not complete geographic counts of every crash within city boundaries. City and county figures overlap and should not be added.
These counts are not adjusted for travel, population, or reporting differences. They cannot rank individual risk, establish fault, or identify a cause. Publisher revisions may change historical figures; the downloadable files preserve this dated snapshot.
Use this brief responsibly
When quoting a Los Angeles figure, include the word “city,” its year, and whether it counts people or collisions. A county total or a death-only statistic answers a different question.
For questions about an actual collision, start with its report and evidence. Los Angeles accident report guide and our plain-English report decoder can help you organize the next step. General statistics do not determine an individual claim.

Common questions
How many people were killed or injured in the Los Angeles OTS city series for 2023?
OTS lists 8,116 victims killed or injured, compared with 8,944 in 2022. This is a combined victim measure under OTS city coverage, not a death-only count or a count of collisions.
Can these figures show who caused my collision?
No. Citywide historical totals do not establish responsibility for a particular collision. An individual assessment requires the relevant evidence and circumstances.
