What is the general rule for driving speed in relation to posted limits?

The general rule for driving speed in relation to posted limits emphasizes that you should never drive faster than the posted speed limit or the conditions allow. This principle ensures that drivers remain within legal speed limits while also taking into account the unique circumstances they may encounter, such as weather conditions, road conditions, traffic, and visibility.

Understanding this rule promotes safety for all road users. If the conditions are poor, such as during heavy rain or snow, driving at the posted speed limit may be unsafe; thus, drivers should reduce their speed accordingly. This balance between legal constraints and situational awareness helps prevent accidents and enhances the overall safety of the driving experience.

The other options do not adequately promote safe driving practices. For example, driving as fast as possible safe risks exceeding safe limits based on conditions, while always driving under the speed limit does not account for situations where the posted limit might be too slow for safe travel under good conditions. Adjusting speed solely based on a vehicle’s performance could lead to disregarding environmental factors, potentially resulting in dangerous driving situations.
