How long can a stop be?

• A. It can last indefinitely
• B. It lasts until the suspect confesses
• C. It lasts exactly 24 hours
• D. An investigative detention must be temporary and last no longer than is necessary to effectuate the purpose of the stop

Answer: (D)

The key idea is that an investigative stop must be temporary and limited to the time needed to accomplish its purpose. A stop isn’t allowed to drag on indefinitely, nor can it be used to force a confession or be fixed to a specific clock like a full day. The question’s correct principle is that the detention should last only as long as it takes to carry out the stop’s objective—verifying the suspicious activity, gathering needed information, or moving to the next appropriate step.

In practice, if officers stop someone for a traffic violation, they may check documents and issue a citation or warning, and the stop ends when those tasks are complete. If new, legitimate suspicion arises, the investigation may continue, but only to pursue that objective and for no longer than necessary to do so.
