CARTMAN DOT Warning Triangles 3-Pack — 17x17in Reflective Triangles with Fillable Bases & Storage Case

The CARTMAN 3PK DOT Warning Triangles are three foldable, highly reflective roadside markers with adjustable empty bases and a storage case for quick, visible vehicle hazard signaling.

These DOT-style warning triangles are designed to improve roadside visibility, whether you face a breakdown, need to mark a lane obstruction, or require an emergency signal while camping. Each triangle measures 17 x 17 inches of reflective paneling and includes a fluorescent plate to increase daytime contrast. The bases ship empty, so you can add sand or other weight to suit wind conditions and surface types, and the compact storage case keeps all three triangles organized for easy access.

How do these triangles increase visibility in low light or bad weather?

The triangles combine high-visibility fluorescent panels with efficient reflective sheeting so oncoming headlights return a bright, noticeable signal. Their triangular shape and standard size follow common visibility expectations, making them easier for drivers to spot and react to.

• 17 x 17 inch reflective panels for strong nighttime reflection
• Fluorescent plate enhances daytime contrast and visibility
• Standard DOT-style triangle shape accepted by many roadside protocols

Are these easy to set up when time is limited?

Yes — the CARTMAN triangles use a folding, snap-fit design that opens and locks without tools. Their quick-deploy mechanism means you can set one or all three in seconds, so you can return to a safe position away from traffic more quickly.

• Tool-free assembly: unfold and snap into place
• Compact folding reduces deployment fumbling in the dark
• Lightweight construction allows fast placement and repositioning

Why are the bases shipped empty, and how does that help me?

The empty bases let you tailor the weight to your situation: add sand, gravel, or small weights to improve stability on windy or inclined surfaces. This customization offers better anchoring than fixed-weight designs, so the triangles stay upright in tougher conditions.

• Fillable base lets you choose weight according to local wind and terrain
• Improved stability when filled compared with lightweight, hollow bases
• Easy to empty for compact storage or transport

What comes with the kit and how should I store it?

The set includes three reflective triangles and a storage case sized to keep them organized and protected. Store the case in your trunk or cargo area to ensure the triangles are available when needed; the case also protects panels from dirt and damage.

• Three DOT-style triangles per kit for multi-directional warning
• Durable storage case keeps components clean and ready
• Folds down compactly so it fits most vehicle trunks or storage compartments

Who is this for: Drivers, fleet operators, RV and camper owners, roadside assistance workers, and anyone who wants a practical, adaptable emergency signaling solution. If you need a portable, quickly deployable set of reflective warning triangles with customizable base weight and tidy storage, the CARTMAN 3PK is designed to meet those needs without tools or complicated setup.
