CARTMAN Foldable DOT Roadside Warning Triangles 3-Pack — 17x17 in Reflective, Sand-Fillable Bases

These CARTMAN warning triangles are a DOT-approved, three-pack set of foldable roadside safety triangles designed to be highly visible, wind-resistant, and easy to store for emergency situations.

When a breakdown or roadside incident forces you to stop, clear, quick signaling matters. CARTMAN's three-piece kit combines DOT/FMVS 571.125-compliant reflective panels with a stable, sand-fillable base and a compact fold-flat design so you can position multiple alerts quickly and keep them stowed without taking up trunk space.

How do these triangles improve visibility for passing drivers?

The CARTMAN triangles use large 17 x 17 inch reflective faces paired with fluorescent plates to catch headlights and daylight alike. Their bright surfaces make them noticeable in low light, daytime glare, and adverse weather so other motorists have more time to react.

• 17 x 17 inch reflective panel with high-contrast fluorescent backing
• Meets DOT/FMVS 571.125 standards for warning devices
• Effective in nighttime, daylight, fog, and rain

Are they stable enough to stay upright in wind and passing traffic?

Each triangle includes a rotatable base that accepts sand or ballast to increase weight and lower center of gravity, so they resist gusts from traffic. At roughly 2.98 lbs per unit when filled, the bases are designed to remain upright on paved shoulders and in many roadside conditions.

• Rotatable base for solid placement and alignment
• Fillable with sand or other ballast for added weight
• Designed to withstand continuous gusts typical near highways

How fast and simple is setup and storage?

These triangles snap open without tools and fold flat for compact storage. The intuitive folding design lets one person deploy all three in just a few minutes, then collapse them for tidy placement in a trunk or vehicle emergency kit.

• Tool-free snap-fit construction for quick deployment
• Foldable panels collapse to a compact footprint
• Pack of three provides multiple points of alert with minimal setup time

What comes in the 3-pack and how should I use them during an emergency?

The kit contains three identical foldable warning triangles so you can create a sequence of markers to guide traffic around your stopped vehicle. Position one near the vehicle, another 10–30 feet behind, and the third farther back to extend the warning zone and increase driver reaction time.

• Three foldable triangular warning devices for layered signaling
• Use staggered placement to create a visible buffer zone
• Compact storage lets you keep all three ready in the trunk or kit

Who is this for: Drivers, fleet operators, tow services, and emergency roadside responders who want DOT-compliant, easy-to-store signaling tools. If you keep an emergency kit in your car, truck, or van, CARTMAN's three-pack offers a practical way to increase roadside safety with visible, wind-resistant triangles that store neatly when not in use.
