What should officers do if they detect the odor of narcotics during a patrol stop?

• A. Ignore it and proceed with the stop
• B. Conduct a search based on probable cause
• C. Immediately call for backup
• D. Notify dispatch and continue the traffic stop

Answer: (B)

Detecting the odor of narcotics during a stop provides a solid, observable basis to search. The smell is an objective clue that drugs are likely present, which meets the probable cause standard to search the vehicle (and, if applicable, the occupants) for contraband. The search can be carried out without a warrant when probable cause exists, and its scope should be limited to areas where narcotics could be hidden. This is the appropriate step because it leverages the odor as credible evidence to locate and seize the drugs, rather than ignoring the signal or continuing the stop without addressing probable cause.
