How many meters behind the faulty vehicle should the warning sign be placed?

[KarterLynn]

Here are the guidelines for placing the warning sign after a vehicle breakdown: 1. On ordinary roads, place the warning triangle 50 meters behind the vehicle during the day and 150 meters behind the vehicle at night; 2. On highways, place the warning triangle 150 meters behind the vehicle during the day and 250 meters behind the vehicle at night; 3. The warning sign is meant to alert others that there is a faulty vehicle in the current lane, so the warning triangle must be placed in the same lane where the vehicle has broken down. Do not place it randomly; 4. If the vehicle breaks down on a curve, the warning triangle should be placed before the curve to alert incoming vehicles to avoid the faulty vehicle.
