Park your vehicle off the roadway to prevent a collision with another vehicle.
In case of serious injury, call 911 or the nearest police station and ambulance.
Turn off the ignition of vehicles involved in the collision to prevent a fire.
If a person is pinned in a vehicle, but unhurt, crawl into the vehicle and try to release them. If an individual is hurt, however, don’t attempt to move them unless the vehicle is on fire. Should the person have to be moved, ensure that the head and spine are firmly supported.
If you have flares or reflective signs, place them 60 metres in front and behind the collision scene as a warning to approaching drivers. Otherwise, use your four-way flashers. Occupants of your vehicle or bystanders should be positioned at both approaches to the collision, standing off the roadway, to warn vehicles
Extinguish the flares when they’re no longer needed.
Even if you haven’t been trained in first aid, you may give the following assistance:
If a person is unconscious, be sure their air passage is clear of foreign material. False teeth, chewing gum, vomit or mucus can block the air passage. If possible, gently turn their head to the side. If the victim is not breathing and you are familiar with mouth-to-mouth or artificial respiration, begin the procedure immediately.
Stop bleeding by applying direct pressure with a clean piece of material over the wound. If there’s a serious head injury, pressure should not be applied.
Reassure the injured and stay with them until an ambulance or other vehicle is available to take them to the hospital.
Give all information on the assistance you have provided to the ambulance attendant and to the police, who in turn can inform the hospital.
