Watch and enjoy the video above…oh and also…..
Here is another reminder from a Tweet by La Guardia
Remember!
At the time of placing the triangles to signal your car in breakdown or accident. 
Put on your vest before leaving the car. On motorways 1 triangle at 50 m from the vehicle, which can be seen from 100 m On double-way tracks: 2 triangles at the front and back at 50 m
