What are posted minimum speed limits?

Posted minimum speed limits indicate the slowest speed at which drivers are permitted to travel under normal driving conditions. They are designed to ensure smooth traffic flow and reduce the potential for accidents caused by vehicles moving too slowly in certain areas, such as highways. If a driver goes below this minimum speed threshold without a valid reason—like an emergency or hazardous condition—they could be cited for impeding traffic.

Options indicating maximum speeds or suggested speeds do not accurately define minimum speed limits. Moreover, while there are speed limits for poor conditions, these are typically not classified as minimum speed limits but rather involve adjustments to maximum or recommended speeds based on the circumstances. Understanding this distinction is essential for safe driving practices.
