Description

The R4-3 sign is an important tool placed on roadways to help drivers understand how to use the lanes effectively. Its message is “SLOWER TRAFFIC KEEP RIGHT,” which is simple but very effective. This sign encourages drivers traveling at a slower speed to stay in the right lane on the road. By doing this, faster vehicles can easily pass them on the left. 

This system helps improve the overall flow of traffic. When slower vehicles do not block the faster ones, it reduces congestion and helps prevent accidents. The R4-3 sign aims to create a safer environment for all road users, including cars, motorcycles, and bicycles. It’s a small reminder that everyone has a role in making road travel smoother and safer, whether you’re driving quickly or taking your time.

Customize your sign’s material and reflective sheeting grade to suit your needs.
