Traffic Stops
Section 66-5-16 — the physical license on the driver whenever driving, and shown on demand
A licensed driver has the driver's license, in its physical form, in their immediate possession at all times when driving, and displays it in physical form on the demand of a magistrate, a peace officer, or a field deputy or inspector of the motor vehicle division.

Not having it is a penalty assessment misdemeanor. A driver charged with it is not convicted if they produce in court a physical license issued to them that was valid at the time of the citation.
For a misdemeanor under the motor vehicle laws, unless a penalty assessment or a warning notice is given, the officer completes the uniform traffic citation with a notice to appear in court, has the driver sign the agreement to appear, gives the driver a copy and releases them from custody.
- To be released, the driver gives a written promise to appear in court or to pay the penalty assessment, or acknowledges receipt of a warning notice.
- A driver who elects to pay a penalty assessment gets the notice with the amount and a reply envelope addressed to the motor vehicle division in Santa Fe. No officer accepts payment of a penalty assessment.
- A driver who declines a penalty assessment notice is given a notice to appear.
- A warning notice is not used as evidence of a conviction for suspending or revoking a license.
The Fourth Amendment sets limits on every stop, and the Supreme Court of the United States has drawn several of them. It has held that a stop is reasonable where the officer has probable cause to believe a traffic violation occurred, whatever the officer's actual motive; that an officer making a lawful stop may order the driver, and the passengers, out of the vehicle; that a passenger is seized by the stop and may challenge it; and that a stop may last no longer than its purpose requires, so it may not be extended for a dog sniff without separate reasonable suspicion. It has also held that consent to a search has to be voluntary, judged on all the circumstances, and that the prosecution does not have to prove the person knew they could refuse. Those holdings are a floor: a state's own constitution and statutes can give more protection than they do, never less.
