In a traffic incident report, what does "LSD" stand for?

In a traffic incident report, "LSD" stands for "Last Seen Driving." This term is used to document the last known location and state of the vehicle or driver involved in an incident, which can be crucial for investigations, especially in situations where a driver may have left the scene of an accident. Capturing information about where the vehicle was last observed can help law enforcement track down witnesses or gather further evidence related to the incident.

The other interpretations of "LSD" do not align with commonly accepted terminology in traffic incident reporting and do not provide the specific context that "Last Seen Driving" offers in the assessment of traffic-related events.
