Warning Triangles

Reflective triangles to alert traffic when you are stopped

Warning triangles are reflective markers you place behind a stopped vehicle to alert approaching drivers. They fold flat for storage and usually include a stable base, making them a simple addition to your roadside kit.

We collect top-rated warning triangles on Amazon so you can compare reflectivity, base stability, and pack sizes. Look for visible reflective panels and a sturdy stand that holds position in wind.

FAQ

How far behind the car should I place one?
Placement distance depends on local rules and road speed, with more distance on highways. Set the triangle far enough back to give drivers time to react, and stay clear of traffic.
How many should I carry?
A multi-pack lets you mark the hazard from more than one angle, which can help on bends or busy roads. Check any requirements for your region.
Can I use them with flares or beacons?
Yes, triangles can be combined with LED beacons or flares for added visibility. Many drivers keep both in their kit for day and night use.
