Minimum speed limits must be obeyed according to which of the following?

Minimum speed limits are established to promote safe and effective traffic flow, regardless of weather conditions, time of day, or the specific location of the road. Understanding this helps clarify that minimum speed limits apply universally when posted, and drivers must adhere to them to ensure their own safety and that of others on the road.

Obeying minimum speed limits at all times, including during adverse weather or rush hours, is crucial as it prevents situations where a vehicle operates too slowly for the conditions, which can lead to accidents or disrupt traffic flow. It's also not limited to residential areas, where slower speeds are often enforced for safety reasons; the requirement holds true on highways and other types of roads as well.

Therefore, the correct response encompasses all possible scenarios, confirming that minimum speed limits must be obeyed consistently, making the choice that indicates "both choices are correct" the appropriate answer.
