Worked examples

Worked example 1

Under Rodriguez v. United States, the duration of a traffic stop is limited to:

  1. 30 minutes
  2. The time reasonably required to address the traffic violation and complete ordinary inquiries (license, registration, insurance, warrant check); extending the stop for unrelated investigation requires independent reasonable suspicion Correct
  3. 1 hour
  4. Officer discretion
Why: Stop's mission ends when traffic-stop tasks are completed (or reasonably should be). Even brief unrelated investigation that prolongs the stop violates the Fourth Amendment unless supported by independent reasonable suspicion.
Statute: Rodriguez v. United States, 575 U.S. 348 (2015)
Worked example 2

SCENARIO. During a traffic stop for a busted taillight, the officer notices a strong odor of marijuana coming from the vehicle. May the officer extend the stop to investigate?

  1. No — taillight is the only allowed inquiry
  2. Yes — the smell of marijuana provides independent reasonable suspicion / probable cause to extend the stop and investigate, including searching the vehicle under the automobile exception Correct
  3. Only if the driver consents
  4. Only at night
Why: Independent reasonable suspicion or probable cause arising during the stop allows extension and additional investigation. Odor of marijuana from the vehicle is generally treated as PC to search under the automobile exception.
