Diagram 513.2A – Maximum Speed of 30 mph Advised at a Bend or Hazard

The Diagram 513.2A sign is a speed advisory sign designed to inform drivers that a maximum speed of 30 mph is recommended when approaching a bend, junction, or another potential hazard. Unlike regulatory speed limit signs, which are legally enforceable, this sign serves as a guidance measure to encourage safer driving speeds in areas where higher speeds may pose a risk.

This sign is commonly used on rural roads, sharp bends, and areas with reduced visibility, helping drivers navigate safely and reduce the likelihood of accidents.

🛣️ Commonly Used on Rural and High-Risk Roads

Found in countryside roads with sharp bends where speed control is necessary.
Used near junctions, steep gradients, or accident-prone areas.
Essential in areas where weather conditions (rain, ice, fog) may increase risks.

Where is the Diagram 513.2A Sign Used?

Understanding Advisory vs. Regulatory Speed Limits

The Diagram 513.2A sign is an advisory sign, meaning the speed recommendation is not legally enforceable. However, drivers are expected to follow the guidance to maintain safety.

Key differences between advisory and regulatory speed signs:

✅ Advisory Speed (Diagram 513.2A) – Recommends a safe speed, particularly at bends or hazards.
🚫 Regulatory Speed Limit (Diagram 670) – A legal speed limit that must be followed.

Although not legally required, failing to adjust speed in response to this sign may still result in loss of control, accidents, or liability in an incident.
