## Facts

- Police received anonymous reports that a motorist was driving erratically and had been drinking all day.
- An officer found a car matching the description near the registered owner’s home.
- When Maria Elena Lopez arrived and exited the car, the officer approached to determine her identity and driving status.
- Lopez stated she did not have a driver’s license.
- Officers detained Lopez for unlicensed driving but did not ask her name.
- Officers searched the vehicle for identification and, in a purse on the front passenger seat, found methamphetamine.
- The trial court suppressed the methamphetamine; the Court of Appeal reversed based on a prior California rule permitting limited vehicle searches for identification; the California Supreme Court granted review.

## Issues

1. Whether the need to obtain a driver’s identification following a traffic stop constitutes an independent, categorical exception to the Fourth Amendment warrant requirement permitting a warrantless vehicle search for identification documents.
2. Whether the prior California rule allowing warrantless vehicle searches for identification when a driver fails to produce ID remains valid after later Fourth Amendment developments, including limits on vehicle searches incident to arrest.

## Decision

- The California Supreme Court reversed the Court of Appeal and affirmed the suppression order.
- The Court held that seeking identification after a traffic stop is not an independent, categorical exception to the Fourth Amendment warrant requirement.
- The Court disapproved the prior California rule to the extent it authorized suspicionless searches of vehicles for identification documents.
- The Court concluded the vehicle search in this case violated the Fourth Amendment, requiring suppression of the methamphetamine.

## Legal Principles

- A warrantless vehicle search requires a recognized Fourth Amendment exception; the mere desire to locate identification documents does not create a standalone categorical exception.
- Exceptions to the warrant requirement are narrowly defined; broad traffic-stop search authority not grounded in established doctrine is improper.
- A lawful detention for unlicensed driving does not, without more, justify searching a vehicle when officers lack probable cause that the vehicle contains evidence of a crime and lack another valid exception (e.g., consent, valid search incident to arrest as limited by governing law, exigency, or a lawful inventory search).
- Prior precedent authorizing suspicionless traffic-stop vehicle searches for identification may be rejected when later doctrinal developments and lack of acceptance elsewhere show it is inconsistent with Fourth Amendment principles.

## Conclusion

The court held that officers may not search a vehicle solely to find identification after a traffic stop when the driver cannot produce a license, absent a traditional Fourth Amendment justification, and it required suppression of evidence found during such an unlawful search.
