Posted speed limit signs are intended for what type of conditions?

Posted speed limit signs are established based on ideal driving conditions, which represent the best-case scenario for road and weather conditions. These limits are designed to enhance safety and traffic flow during normal circumstances, reflecting the maximum speed at which vehicles should be operated safely without incurring risks from factors such as weather, traffic congestion, or road conditions.

While hazardous, emergency, and variable conditions may require adjustments to driving speeds for safety, the posted limits specifically cater to ideal conditions. This allows drivers to understand the safe speed to travel when conditions are favorable, ensuring a baseline for compliance that can be modified based on situational needs.
