DIAGRAM 502.3 – 400 Yards to a Junction Ahead Controlled by a Stop Sign
The DIAGRAM 502.3 STOP 400 Yards sign is an essential advance warning sign designed to inform drivers that a STOP-controlled junction is ahead in 400 yards. This sign plays a critical role in enhancing road safety, reducing sudden braking, and ensuring a smoother transition into stop-regulated junctions.
Featuring bold black text on a white background, the sign is highly visible and easily readable, providing motorists with ample time to prepare for a mandatory stop.
