Day of WeekDefinition: The day of the week on which the crash occurred.Circle or block out the day of the week of the crash. Block out the letter representing the day of the week.Rationale: Permits the user to quickly obtain this information for crash analyses without having to translate thedate.Military TimeDefinition: The time (00:00–23:59) at which the crash occurred. Indicate time in military format.Indicate the time of day the crash occurred (closest estimate) using four digit military times.If citation is issued, be sure time of the offense on the citation and time of the crash agree.Rationale: Important for management/administration, evaluation, and linkage.DLD NumberThe DLD Case number is assigned by the Driver License Division (DLD). The DLD number is used to locateand track crashes by other agencies and data users. This is for Drivers License Division use only. The boxshould be left blank by all law enforcement agencies.Place Where Crash OccurredLOCATIONEnforcement, highway design and traffic control improvement programs depend upon knowledge of exact crashlocations for their effectiveness. It is important that distances to reference points be accurately measured andrecorded by the investigating officer. For rural crashes, when tape measurements are not practical because of thedistances involved, the investigating officer should drive to the nearest intersection, reference point or otheridentifiable landmark and record the distance carefully using the patrol vehicle odometer. Measurements shouldalso be given to permanent landmarks near the crash scene, such as culverts, buildings, or physical structures,etc. It is essential that the crash location is described so the site can be located by traffic engineers orinvestigators for subsequent on-scene inspections.If a crash occurs on private property, identify the property and indicate the address where it is located and thedirection the vehicle was going at the time of the crash.16
Location fields are critical for UDOT. An agency should include GPS information if available. Continue to fillout the entire location section when using GPS. County information is always required. Many localjurisdictions use this information for city planning and engineering and do not have access to GPS maps.Definition: Exact location on the roadway to document where the first harmful event of the crash occurred.Rationale: Critical for problem identification, prevention programs, engineering evaluations, mapping, andlinkage purposes.CountyDefinition: The county or equivalent entity in which the crash occurred.Use the appropriate two-digit code to indicate the county where the crash occurred. Do not abbreviate.

This data is Important for intrastate comparisons as well.City or Town of JurisdictionDefinition: The city/town (political jurisdiction) in which the crash occurred. If applicable, indicatethe city or town where the crash occurred. Note: Any city or town, whether it is incorporated orunincorporated, can be used for location purposes.

(EMS, hospital,roadway, etc.)Distance from City Limits of Nearest TownIf the crash occurred outside the limits of a city or town, indicate the distance and direction fromthe nearest reference point, mile post, city or town limits. Miles should be indicated in tenths.Example: 1.7 miles or 0.3 miles Indicate distance from city limits or nearest town in miles.And then indicate which direction: north; south; east; or west; of the town as well as the city ortown name that the crash occurred.17
