California’s expansive road system was among the nation’s worst ranked, according to a report from a research firm out on Tuesday. Hawaii’s roads were ranked as the nation’s worst.
ConsumerAffairs, a non-government research firm, used its own data combined with data from the U.S. Department of Transportation, the Insurance Institute for Highway Safety, and the Federal Highway Administration to rank the best and worst road conditions for travel by state.
Its ranking criteria included Federal Highway Administration road quality, motor vehicle crash fatalities, amount spent per mile of road and vehicle miles traveled.
Hawaii had the worst roads in the U.S., followed by Rhode Island, Louisiana, California and Wisconsin, according to the ConsumerAffairs report.
More than a quarter of Hawaii’s urban roads measured in at more than 170 inches per mile on the International Roughness Index, which is a measure of how much a vehicle vibrates based on the roughness of the road and how the wheel hits it. Roads with an IRI at or above 170 inches per mile are considered in poor condition, according to ConsumerAffairs.
