R2-1 Speed Limit Signs: Complete Guide to Regulatory Traffic Control

R2-1 Speed Limit signs represent one of the most recognizable and essential regulatory traffic control devices on our roadways. These critical safety tools establish the maximum legal speed limits for vehicles, helping to maintain order, reduce accidents, and protect all road users. As specialists in high-quality traffic signage, LED Lighting Solutions offers a comprehensive selection of R2-1 Speed Limit signs that meet all federal and state requirements while providing exceptional visibility and durability.

What Are R2-1 Speed Limit Signs?

R2-1 signs are regulatory traffic control devices that display the maximum legal speed limit for a particular road segment. These signs are standardized according to the Federal Highway Administration's Manual on Uniform Traffic Control Devices (MUTCD), ensuring consistency across the United States. The classic white rectangular sign with bold black numerals and "SPEED LIMIT" text is immediately recognizable to drivers nationwide.

Key characteristics of standard R2-1 signs include:

• White background with black text and border
• Rectangular shape (typically 24"×30" for conventional roads)
• "SPEED LIMIT" text above the numeric value
• Speed value displayed in large, clear numerals
• Retroreflective materials for nighttime visibility
