How sources and Utah crash data are used
The site uses official public sources where available and states when a dataset has limits that prevent a broader conclusion.
Legal and regulatory sources
Utah legal citations link to the Utah Legislature. Federal carrier, hours-of-service, insurance, and electronic logging information links to FMCSA. Agency pages are used for crash reports, road regions, public data, and local transportation context.
Crash data method
The 2022 through 2024 report queries UDOT's public Crash Locations layers and filters COMMERCIAL_MOTOR_VEH_INVOLVED to Y. Injury-or-fatal totals exclude No Injury/PDO. County and route tables group the same filtered records. Route tables exclude records with a blank route field.
Data limits
UDOT describes the service as de-identified crash-location data and notes that recent records can be delayed or corrected. The commercial motor vehicle field does not mean every record involved a tractor-trailer. Aggregate data cannot establish fault, liability, coverage, injury value, or the outcome of a particular claim.
Access and review date
The crash layers used for the report were accessed July 21, 2026 and rechecked against the live layers on August 30, 2026. The summarized CSV and methodology record, version 1.1, are downloadable so readers can inspect the published totals and query definitions.
