IntroductionIdaho Traffic Crashes 2016 provides an annual description of motor vehicle crash characteristics forcrashesthathaveoccurredonpublicroadswithintheStateofIdaho.Thisdocumentisusedbystateandlocal transportation, law enforcement, health, and other agencies charged with the responsibility ofcoping with the increasing costs of traffic crashes. Agencies use the data to identify traffic safetyproblemsandtargetareasforthedevelopmentofcrashreductionandinjurypreventionprograms.Atrafficsafetyproblemisanidentifiablesubgroupofdrivers,pedestrians,vehicles,orroadwaysthatisstatistically higher in crash experience than normal expectations. Problem identification involves thestudyofrelationshipsbetweencrashesandthepopulation,licenseddrivers,registeredvehicles,vehiclemilestraveled,andcharacteristicsofspecificsubgroupsthatmaycontributetocrashes.This document is divided into two major sections: a statewide crash summary and a breakdown ofcrashes by identified problem areas.

All lawenforcement agencies use a standard crash reporting software program to enter the data andelectronically submit thedata to theDepartment, asdesignated in IdahoCode49‐1307. The resultingnumbersareconservativesince thedatabaseconsistsofonlycrashes investigatedby lawenforcementofficers.Priorto2006,onlycrashesresultingininjuryordeathofanyperson,ordamagetothepropertyofanyonepersoninexcessof$750wereincluded.Thelawwasamendedin2006tocrashesresultinginexcess of $1,500 property damage to any one person. Crashes resulting in injury or death remainedunchanged. Crashesthatareexcludedincludethosethatdonotoccuronapublicroadway,occuronaroadwayonprivateproperty,orareintentionalacts.Whenexamining anyof the statisticsherein, it is important todistinguishbetween the threedifferentlevelsofcrashdata:thecrashlevel,theunitlevel,andthepersonlevel.Forexample,location,date,time,severity, and weather conditions are specific to the entire crash; vehicle type, extent of deformity,contributing circumstances, and events are specific to each unit in the crash; and lastly, age, gender,injurytype,andprotectivedeviceusearespecifictoeachpersoninvolvedinthecrash.Eachcrashmustinvolveatleastonemotorvehicleandeachmotorvehiclecontainsanynumberofpeople,includingzero.Eachcrashisclassifiedbythemostsevereinjurythatresultedfromthecrash.Therefore,eachfatalcrashresultedinat leastonefatalitybutmayhavealsoproducedanynumberandcombinationofadditionalfatalitiesandinjuries.The Division of Motor Vehicles and the Economics and Research Section (Idaho TransportationDepartment) provide information on licensed drivers, registered motor vehicles, driver’s licensesuspensions, and driver’s license convictions.

Self‐reported seat belt use can be biased because of the penalties involved for not wearing a seat belt(meaningpeoplemisrepresenttheirbeltusetoavoidaticket). Thenumberofpeopleusingseatbelts ishigher for the less severe injury categories because of this bias, but also because seat belts lessen theseverityofinjuriessustainedincrashes.

DistractedDrivingDistracted driving crashes are those where investigating law enforcement officer indicates that eitherinattentionoradistractioninoronthevehiclewasacontributingfactorinthecrash.Distraction is defined by theNationalHighwayTrafficSafetyAdministrationasa specific typeof inattention thatoccurswhendrivers divert their attention away from the task of driving to focus on another activity. Distraction iscategorized into the three following types: visual (taking your eyes off the road),manual (taking yourhandsoffthewheel),andcognitive(takingyourmindofftheroad).
