The Indiana statute requires drivers to “provide” either their identifying information (name, address and date of birth) or their drivers license. Since the word provide is used with mere information (i.e. telling the officer), showing your license should be sufficient under state law.
The statutes do require people to sign when you’re charged with a misdemeanor, but that does not apply to most traffic tickets. We have seen versions of tickets where there is no spot for the driver to sign, but also others where there is a spot. If the officer insists that you sign, make sure that you’ve recorded this on audio and/or video, and that you only roll down the window if ordered to do so. See our video at bottom about the difference between an order and a request.
