What is the maximum speed limit in Pennsylvania under proper conditions?

In Pennsylvania, the maximum speed limit under proper conditions on highways is generally 55 miles per hour. This limit is established to ensure safety on roadways, balancing the need for efficient travel with the importance of maintaining safe driving conditions. While some highways may allow higher speed limits, particularly in rural areas or certain interstate sections that may permit 65 or even 70 miles per hour, the standard limit for most roadways across the state remains at 55 miles per hour unless otherwise posted.

Proper conditions refer to factors such as weather, visibility, and traffic density, which can influence the safe driving speed. Drivers are expected to adjust their speed according to these conditions, and violations of the posted speed limits can lead to penalties, ensuring that all road users adhere to safe practices.
