State transportation officials say “road rage” is playing a larger role in accidents in roadway construction zones. Jerry Dickinson of the Iowa D-O-T says the number of accidents in road work zones continues to climb. Seventeen people died in work zone car accidents last year. He says the majority of those killed were motorists, not construction workers.Dickinson says bad judgement and inattention account for most of the work zone accidents.Dickinson says there will be five-hundred permanent road work zones in Iowa this summer. As many five-hundred short-term road fix-up projects will be on-going, too, as crews patch cracks and conduct other routine road maintenence. Dickinson urges Iowans to slow down and pay attention to the signs in work zones.
