Description

The R4-18 sign is an important road safety measure intended to maintain order on highways and roadways. It clearly states, “DO NOT PASS ON SHOULDERS,” which is a reminder for drivers to refrain from overtaking other vehicles on the road’s shoulder. This message is crucial because passing on the shoulder can be unsafe and lead to accidents. Shoulders are often narrower and not designed for regular vehicle use, making it difficult for drivers to react in case of an emergency. By following this guideline, drivers contribute to safer roads for everyone, reducing the risk of dangerous situations and promoting better roadway discipline.

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