What typically signifies that a civil traffic stop has concluded?

A civil traffic stop is typically considered concluded when the citation has been signed. This indicates that the officer has completed the necessary legal procedures associated with the traffic stop. The signing of the citation signifies that the driver has acknowledged the violation and has received a copy of the citation, which includes information about the violation, potential penalties, and court dates.

While the other options relate to aspects of the traffic stop, they do not mark its conclusion. Identifying the driver is part of the initial engagement but does not signify the end of the stop. Searching the vehicle may occur during the stop, but it is not a standard conclusion point, as searches can be part of ongoing enforcement activities. Completing the report, while important for record-keeping, may happen after the driver leaves the scene and does not denote the immediate conclusion of the traffic stop itself. Thus, the act of signing the citation is the clear indicator that the civil traffic stop has reached its end.
