CARTMAN 3-Pack DOT Warning Triangles — 17 x 17 in Foldable Reflective Panels with Empty Fillable Bases

The CARTMAN 3PK DOT Warning Triangles are a compact, foldable set of highly reflective roadside markers with empty bases and a storage case for customizable weight and quick deployment.

If you need visible, durable warning triangles for breakdowns, towing, construction, or camping, this three-pack from CARTMAN gives you three 17 x 17 inch reflective panels with fluorescent backing, snap-fit assembly and an empty base you can fill to match local wind and road conditions. These triangles meet practical DOT-style design expectations, fold flat for storage, and come with a zippered carrying case so you can keep them in your trunk or service vehicle without taking up much space.

How do these triangles improve roadside visibility?

The CARTMAN triangles combine large reflective surfaces and fluorescent plates to increase noticeability in darkness, low light, or poor weather. Their 17 x 17 inch faces present a clear, familiar silhouette that motorists recognize as a hazard marker.

• Large 17 x 17 inch reflective panels for clear nighttime reflection
• Fluorescent backing enhances daytime visibility and contrast
• Distinct triangular shape signals hazard to approaching drivers
• Reflective material works with car headlights for long-range detection

What does the empty base mean and why is it useful?

Each CARTMAN triangle ships with an unfilled base so you can add sand, gravel, or other ballast to achieve the weight and stability required for your environment. This flexibility helps maximize stability on windy roads or uneven surfaces without permanently increasing kit weight for storage.

• Empty base accepts sand or ballast to increase weight as needed
• Adjustable stability for different wind and road conditions
• Easier to transport when bases are unfilled and lighter
• Allows quick on-site customization for short- or long-term placement

How simple is setup and storage with this three-pack?

Setup requires no tools: the triangles fold open and snap into place, then mount to the base. When finished, each triangle collapses flat and fits back into the included case so the kit stays organized and ready for the next use.

• Tool-free snap-fit design for fast deployment
• Folding panels collapse flat for compact storage
• Zippered storage case keeps all three triangles together in your vehicle
• Quick to remove from case and position beside disabled vehicle or campsite

Where can I use these warning triangles and what should I expect?

• Suitable for cars, trucks, RVs, trailers and work vehicles
