The panic attacks soon could be a thing of the past for drivers searching frantically through their glove boxes for a proof-of-insurance card to show police.
Missouri Gov. Jay Nixon signed legislation that will make it easier for people to show proof of insurance on their smart phones.
The bill applies to traffic stops and drivers who want to register their vehicle at a license office.
Nixon called the measure "common sense legislation."
The state insurance department says more than two dozen states have passed similar measures. The law will take effect on Aug. 28.
