What is the general speed limit on highways unless posted otherwise?

The general speed limit on highways is typically set at 65 mph unless there are signs indicating otherwise. This speed limit is established to promote safe driving while allowing for efficient travel across long distances. It's important to follow this guideline to reduce the risk of accidents, as higher speeds can lead to more serious collisions and decreased reaction times. In addition, speed limits can vary by state or region, so it's important for drivers to be aware of local laws and adjust their speed accordingly. Remember that variations in speed limits may be posted in construction zones, urban areas, or in areas with specific safety considerations.
