What document must drivers present when requested by a law enforcement officer in Texas?

When a law enforcement officer requests identification from a driver in Texas, the document that must be presented is a valid driver's license. This requirement ensures that the officer can confirm the driver's identity, driving privileges, and legal status to operate the vehicle. The driver's license serves as the primary form of identification regarding the ability to drive and verifies that the driver is legally registered with the state.

While other documents like a valid insurance card, vehicle registration documents, and personal identification cards can also be relevant and may be requested in specific situations, they are not mandatory to show when a law enforcement officer stops a driver. The driver's license is specifically required by law for identification purposes during a traffic stop or in any situation where proof of driving eligibility is needed.
