Summary

This report, published by the Idaho Transportation Department’s Office of Highway Safety, provides a comprehensive statistical analysis of motor vehicle crashes in Idaho for the year 2010. The document aims to assist state and local agencies in identifying traffic safety problems and targeting crash reduction programs by examining crash characteristics, contributing factors, and economic impacts. The data is derived from the Idaho Transportation Department State Crash Database, which includes crashes investigated by law enforcement that resulted in injury, death, or property damage exceeding $1,500. The study found that total motor vehicle crashes decreased by 2.0% from 2009 to 22,555 in 2010. Fatalities dropped by 8% to 209, and the statewide fatality rate per 100 million vehicle miles traveled declined to 1.34. Despite the overall decrease in crashes, rural roadways accounted for 77% of fatal crashes, compared to 61% of all crashes occurring on urban roadways. Single-vehicle crashes, while representing only 34% of total incidents, accounted for 60% of fatalities, with overturns being the leading harmful event in these cases. Key contributing factors included impaired driving, which was involved in 46% of all fatalities, and aggressive driving, which contributed to 52% of all crashes and resulted in 88 deaths. Distracted driving was a factor in 26% of crashes, causing 60 deaths. Seat belt usage remained a critical issue; observed use decreased slightly to 78%, yet only 47% of occupants killed in crashes were wearing seat belts. The report estimates that 36 unbelted occupants might have survived if restraints had been used. Youthful drivers (ages 15–19) were 2.5 times more likely than other drivers to be involved in fatal or injury crashes. The economic cost of crashes in Idaho was estimated at approximately $2.46 billion in 2010, equating to $1,577 per resident. The report highlights that society bears nearly 75% of these costs through insurance premiums, taxes, and medical charges. The findings underscore the disproportionate risk associated with rural driving, impaired operation, and restraint non-use, providing a data-driven basis for continued safety interventions in these specific areas.

Key finding

Idaho experienced 209 traffic fatalities in 2010, with 77 percent occurring on rural roadways and 46 percent linked to impaired driving.
