At what distance from the vehicle set the sign "Emergency stop"?
In populated areas - not less than 15 m, outside populated areas - 30 m.✓Correct answer
In populated areas - at least 10 m, outside populated areas - 20 m.
In settlements - at least 5 m, outside settlements - 10 m.
Explanation
The warning triangle must be far enough behind the vehicle to give approaching drivers time to react: at least fifteen metres in a built-up area and thirty metres outside one. The shorter proposed distances do not provide the prescribed minimum warning interval.
