Broke down? Turn your phone into a warning sign.

Tap the SOS button and this phone becomes a full-screen flashing red-and-white sign. Set it upright at the back of your truck so traffic sees you early.

SOS

Warning: the sign flashes bright lights. Tap anywhere on the flashing screen to stop it.

1. 1. Turn your screen brightness all the way up.
2. 2. Tap SOS, then set the phone upright and visible at the back of your truck, facing traffic.
3. 3. Stay clear of the travel lane while you wait.

This sign is a supplement to your hazard lights and warning triangles — not a legal replacement for them. Use your hazards and triangles too, every time.
