Correct Answer:

65 mph, unless otherwise posted

Explanation:

The maximum speed limit on Pennsylvania interstate highways is typically set at 65 mph unless posted otherwise. This speed limit is designed to ensure safety while allowing for efficient travel on the interstate system, which is engineered for higher speeds than regular roads. It's important to note that speed limits may vary in specific areas due to factors such as construction zones, urban development, or particular traffic conditions. Drivers should always be attentive to the posted speed limit signs, as they will indicate when a different speed limit is in effect. Understanding the established speed limits is crucial for maintaining lawful driving and ensuring the safety of all road users.
