HY-KO 16In Slow Sign 18" x 18

The HY-KO A20508 is a slow-moving vehicle sign designed for agricultural and industrial equipment. It measures 18 inches by 18 inches and features a 16-inch reflective surface. The sign alerts approaching traffic to reduced speeds on public roads.

Line protection category and 16-inch reflective area

This circuit breaker and line protection accessory provides a 16-inch reflective area for visibility. It comfortably handles daytime and nighttime road use for tractors and implements. The 18-inch square frame offers standard mounting compatibility for common brackets.

Replaces worn or missing SMV emblems

The sign upgrades faded, cracked or missing slow-moving vehicle emblems on farm machinery. The jump is worth it when the existing triangle no longer meets reflectivity standards for road travel. First listed by the manufacturer on February 14, 2025.

Will the HY-KO A20508 16In Slow Sign mount on an existing 18" x 18" sign post?

How can I verify the HY-KO A20508 16In Slow Sign is correctly installed and visible?

Once mounted, the 16-inch "SLOW" lettering should be clearly legible from the road and the sign should sit firmly without wobble.

Does the HY-KO A20508 16In Slow Sign include mounting hardware or must I buy it separately?

The product is the sign panel only; mounting brackets, bolts or posts are not included and must be purchased separately.
