Photo Enforcement Vans More Effective Than Signs, Police Cars, U. of I. Study Says

Police vans equipped with radar cameras to enforce the speed limit are the best available tool to force motorists to slow down in construction zones, according to a new study by University of Illinois researchers. The Illinois State Police photo vans are capable of identifying scores of speeding scofflaws across multiple lanes of traffic in only a few minutes, ringing up minimum $375 speeding tickets that are sent in the mail for the work-zone violations. According to law-enforcement officials, this process is much more efficient and safer for police officers than pulling over individual speeders as traffic rushes past.
