WalletHub says Iowa ranks in the top 10 in three individual categories, share of rush hour traffic congestion, cost of ownership and maintenance, and traffic and infrastructure. None of Iowa's bordering states rank in the top 10 overall. WalletHub says the worst state for driving is Hawaii. A full list of states is available here.
