Are you required to carry your driver's license while driving?

Every US state requires drivers to carry their valid driver's license whenever they are operating a motor vehicle. Failure to produce the license on demand is generally a citable offense, though usually a minor one ('failure to display') that can be dismissed by proving you held a valid license at the time of the stop. The license also must be the current valid one (not expired, suspended, or revoked) — driving on an expired or suspended license is a more serious offense. Some states allow electronic versions of the license to be displayed on smartphones, but a physical license is still the standard in most jurisdictions.
