Question

what you must do when you see an road accident

Answer 1

Instead of waiting helplessly for the ambulance, first aid should be given..
First clear the accident spot and take the victim on the roadside with the help by yourself or with the help of some people if needed.
In case of bleeding, take a handkerchief and wrap it around your finger... Clear all the clotting inside the victim's mouth and if he feels like vomiting after that then help him to do so.

Answer 2

u should immediately stop ur vehicle aside and call the ambulance and then give him a first aid.
