What is the advisory speed limit in a 20 mph zone?

In a 20 mph zone, the advisory speed limit typically indicates that drivers should not exceed the specified speed for the safety of all road users, especially in areas where children or high pedestrian activity is expected. While the specific advisory speed may vary depending on local regulations, in most jurisdictions, the advisory speed limit is set slightly above the standard limit to account for potential variations in traffic conditions.

Option B, which states a 30 mph advisory speed limit, aligns with common practice in various localities where the advisory speed serves as a guideline for safe driving behavior, suggesting that while 20 mph is the maximum speed for safety, an experienced driver can safely navigate at a speed of up to 30 mph depending on conditions. This allows for flexibility while maintaining safety in designated low-speed zones.

However, it’s crucial for drivers to remain vigilant and adapt their speed according to the actual environment, weather, and presence of pedestrians or potential hazards.
