18" Heavy-Duty Safety Cone for Semi-Truck & Fleet Use

Tough, high-visibility 18-inch safety cone built for real-world semi-truck and fleet operations. Whether you’re handling roadside breakdowns, trailer inspections, yard traffic, or shop safety, this cone delivers dependable visibility and stability where heavy-duty equipment is in motion.

Manufactured from one-piece, heavy-duty PVC, is designed to flex on impact and hold up to repeated use around tractors and trailers. Its 5-pound weighted base helps prevent tipping from wind, passing trucks, or yard traffic—making it a reliable choice for trucking environments where lighter cones fall short.

The bright safety-orange, UV-stabilized finish with reflective tape provides excellent visibility day or night and resists fading during long-term outdoor use. Designed to meet MUTCD and NCHRP-350 standards (when applicable), this cone fits seamlessly into professional fleet safety and DOT-compliant operations.
