Which condition is acceptable for making a temporary stop on the roadway?

Making a temporary stop on the roadway is governed by specific regulations to ensure safety and order. Being directed by a police officer is a recognized and valid reason for stopping, as their instructions are meant to maintain traffic flow, respond to emergencies, or manage situations that require immediate attention.

In contrast, personal errands, dropping off passengers, or the driver being sleepy do not align with established traffic laws that prioritize the safety and efficiency of roadways. While dropping off passengers may sometimes be permissible in designated areas, it is not universally justified in all situations, especially if it impedes traffic or is done illegally. Additionally, stopping due to fatigue is a concern, but it should ideally be addressed prior to beginning a trip, rather than as a reason to stop on the roadway itself. Hence, being directed by a police officer is the most appropriate and acceptable condition for a temporary stop in this context.
