Official 2022-2024 ALDOT Crash Data
Jefferson County Accident Trends
Jefferson County accident trends show fewer reported crashes in 2024 than in 2022, but the story is more complicated than a single downward line. Combining the intersection and non-intersection counts in Alabama Department of Transportation county maps, the county recorded 28,433 crashes in 2022, 26,932 in 2023, and 26,354 in 2024. That is a two-year decrease of 2,079 crashes, or about 7.3%.
Fatalities did not follow the same smooth pattern. ALDOT reported 96 Jefferson County traffic fatalities in 2022, 114 in 2023, and 103 in 2024. This guide explains what changed, what remained relatively stable, and what these aggregate figures cannot establish about a particular Birmingham-area collision.

Official Sources and Calculation Method
This analysis uses ALDOT’s 2022 Crash Facts, 2023 Crash Facts, and 2024 Crash Facts reports. Earlier and current editions are available through the ALDOT Crash Facts archive.
Each report publishes one county map for intersection-related crashes and another for non-intersection-related crashes. The total shown here is the sum of those two mutually presented categories for Jefferson County in the same report year. Percent changes are calculated from the unrounded annual counts and rounded to one decimal place for readability.
The reports state that crash-data analysis is provided by the Center for Advanced Public Safety at The University of Alabama using data supplied by the Alabama Law Enforcement Agency, with additional data and funding from ALDOT. The figures are reported-event counts, not estimates of every collision that may have occurred.
Jefferson County Accident Trends at a Glance
| Year | Intersection crashes | Non-intersection crashes | Combined crashes | Traffic fatalities |
|---|---|---|---|---|
| 2022 | 17,389 | 11,044 | 28,433 | 96 |
| 2023 | 16,773 | 10,159 | 26,932 | 114 |
| 2024 | 16,215 | 10,139 | 26,354 | 103 |
Three-year direction: combined crashes fell 5.3% from 2022 to 2023, then 2.1% from 2023 to 2024. Across the full period, combined crashes fell 7.3%. Traffic fatalities rose sharply in 2023 and then declined in 2024, ending 7.3% above the 2022 count.
Total Reported Crashes Declined in Both Comparisons
The largest annual reduction occurred between 2022 and 2023, when the combined Jefferson County count fell by 1,501 crashes. The next year brought a smaller reduction of 578 crashes. The pace of decline therefore slowed, even though the direction remained downward.
A reduction in total reports is meaningful, but it is not enough by itself to explain why the count changed. Travel volume, construction, enforcement, weather, reporting practices, and changes in where people live or work can all affect annual totals. A three-year sequence is also too short to declare a permanent long-term trend.
For the newest single-year context, see our detailed Birmingham car accident statistics guide. It separates Jefferson County figures from statewide Alabama measures throughout.
Intersection and Non-Intersection Crash Trends
Intersection-related crashes were the larger category in every year reviewed. They accounted for approximately 61.2% of the county’s combined count in 2022, 62.3% in 2023, and 61.5% in 2024. The share changed little even as the number of crashes declined.
- Intersection-related: 17,389 in 2022 to 16,215 in 2024, a decline of 1,174 crashes or about 6.8%.
- Non-intersection-related: 11,044 in 2022 to 10,139 in 2024, a decline of 905 crashes or about 8.2%.
The relatively steady split does not identify a particular dangerous crossing. County maps aggregate thousands of locations. For location-level context, use our guide to dangerous intersections in Birmingham, which explains the limits of rankings and how to check current conditions.
Fatalities Rose in 2023 Before Falling in 2024
Jefferson County traffic fatalities increased from 96 in 2022 to 114 in 2023, an 18.8% rise. The count then fell to 103 in 2024, a 9.6% year-over-year decrease. Despite that improvement, the 2024 count remained seven deaths above 2022.
ALDOT’s county maps also identify fatalities with apparent alcohol or drug involvement: 9 in 2022, 16 in 2023, and 8 in 2024. These are officer-reported apparent-involvement figures, not final criminal or civil findings. The category should not be treated as a count of cases in which impairment was judicially proven.
Fatalities and total crashes can move differently because crash severity varies. Speed, road-user type, restraint use, impact configuration, emergency response, and many other circumstances can change the outcome of an individual event. Aggregate county totals do not isolate those factors.
Jefferson County and Statewide Alabama Trends
Alabama’s total reported crashes also declined across the same period: 144,263 in 2022, 143,487 in 2023, and 140,118 in 2024. That equals a statewide two-year reduction of about 2.9%, compared with Jefferson County’s 7.3% reduction in the combined county-map counts.
Statewide fatalities moved from 986 in 2022 to 975 in 2023 and 967 in 2024. Jefferson County’s 2023 fatality increase therefore differed from the statewide direction that year. This comparison describes simultaneous patterns; it does not establish that a county policy, roadway change, or enforcement action caused the difference.
Birmingham Data Is Not the Same as Jefferson County Data
Jefferson County includes Birmingham, Bessemer, Hoover portions, Homewood, Mountain Brook, Vestavia Hills portions, Trussville portions, and many other municipalities and unincorporated communities. The county figures on this page cannot be relabeled as Birmingham city totals.
City boundaries, mailing addresses, police jurisdictions, and county lines are different geographic concepts. A crash described informally as a “Birmingham accident” may have been investigated by another agency or may have occurred outside Birmingham’s corporate limits. Precise local analysis begins with the crash location and the investigating agency.
What These Accident Trends Can and Cannot Show
The three-year data can show direction, magnitude, and the balance between ALDOT’s intersection and non-intersection categories. It can help residents, planners, and drivers ask better questions about where more detailed analysis may be useful.
It cannot prove that a particular road became safer, identify fault in a collision, measure unreported crashes, or predict whether a person will be injured. It also cannot reveal a city-only pattern because the source geography is the entire county.
Annual changes deserve context rather than a simple “safer” or “more dangerous” label. The county had fewer combined crashes in 2024 than in either prior year, yet fatalities remained above the 2022 count. Both facts matter.
Major Jefferson County Roads Need Location-Specific Review
Jefferson County contains dense urban streets, suburban arterials, rural roads, and major freight and commuter routes. Countywide totals combine very different environments. Drivers seeking corridor-specific information can review our pages about accidents on I-65, I-20, I-59, I-459, and U.S. 280.
For current traffic incidents and road conditions, consult ALGO Traffic. Live traffic information serves a different purpose from annual crash statistics and should not be used as a substitute for an official crash report.
Trend Data Does Not Decide an Individual Accident Claim
A county trend may provide background, but responsibility for a specific collision depends on evidence tied to that event. Useful material may include the crash report, photographs, video, vehicle data, witness statements, medical records, roadway measurements, and applicable traffic rules.
Even a history of crashes at one location does not automatically prove negligence. The earlier events may involve different movements, weather, lighting, vehicles, or roadway configurations. Anyone preserving evidence can use the step-by-step Birmingham Accident Resource Center and the broader Alabama Injury Law Center.
Different vehicle types also raise different evidence issues. See the focused guides for a Birmingham car accident, commercial truck collision, or motorcycle accident.
How to Find More Specific Crash Information
- Confirm the exact location, date, time, and investigating agency.
- Obtain the official crash report and check how the location is recorded.
- Use ALDOT’s annual reports for statewide and county context.
- Check the City of Birmingham open-data portal for available city datasets and their date coverage.
- Request records from the agency that maintains the needed report or dataset.
- Compare definitions before combining figures from different sources.
Always record the source edition and retrieval date. A later revision, different geographic filter, or different definition of a reportable crash can produce a different total without either source necessarily being wrong.
Frequently Asked Questions About Jefferson County Accident Trends

Yes. The combined ALDOT county-map count fell from 28,433 in 2022 to 26,354 in 2024, a decrease of about 7.3%.
How is the combined crash total calculated?
It adds ALDOT’s Jefferson County intersection-related and non-intersection-related counts for the same report year.
Are these Birmingham city accident totals?
No. They cover all of Jefferson County, including Birmingham, other municipalities, and unincorporated areas.
Which year had the most Jefferson County crashes in this comparison?
2022 had the highest combined count at 28,433. The comparison covers only 2022 through 2024.
Which year had the most traffic fatalities?
2023 had 114 Jefferson County traffic fatalities, compared with 96 in 2022 and 103 in 2024.
Did intersection crashes decline?
Yes. They fell from 17,389 in 2022 to 16,215 in 2024, a decrease of about 6.8%.
Did non-intersection crashes decline?
Yes. They fell from 11,044 in 2022 to 10,139 in 2024, a decrease of about 8.2%.
Does a falling crash count mean every road became safer?
No. County totals do not establish the trend on an individual street, intersection, or highway segment.
Can county trends prove fault in my accident?
No. Fault depends on evidence and law specific to the collision. Aggregate statistics are background information.
Where can I check future editions?
ALDOT publishes annual Crash Facts reports and maintains an online archive. Check the report year and definitions before comparing new figures with this page.
The Clearest Reading of the Three-Year Trend
Jefferson County’s combined reported crash count declined in both annual comparisons and was 7.3% lower in 2024 than in 2022. Intersection and non-intersection categories both fell. Fatalities, however, rose in 2023 before partially receding in 2024 and remained above the 2022 count. The responsible conclusion is therefore specific: fewer total crashes were reported across the period, while the severity picture was uneven.
Use these figures as county-level context, not as Birmingham city totals or proof about an individual collision. The underlying report, exact location, and event-specific evidence remain essential.
