do first aid
A first aid person is commonly referred to as a "first aider." This individual is trained to provide initial medical assistance and support in emergencies until professional medical help arrives. In some contexts, they may also be called a "first responder," especially if they are among the first to arrive at the scene of an emergency.

The responsibility for preserving the accident scene typically falls to the first responders at the scene, such as police, fire, or emergency medical personnel. They are trained to secure the area, ensure safety, and prevent contamination of evidence. Additionally, the organization or company involved in the incident should have designated safety officers or points of contact who are responsible for coordinating with authorities and preserving the scene for investigation.

Secure the accident scene, using guards, or roping off the area, if available
If you are involved in the accident it is a crime to leave the scene, but if you are a witness or bystander there is no problem.
If you are on the scene of an accident and there is someone who appears to be injured, for example this person is on the ground and not getting up, or is bleeding heavily, or seems to be unconscious, and if you have some training in first aid, and if there is no more qualified person than yourself who is already delivering first aid, then you should by all means deliver first aid. If you are not trained to deliver first aid you can still phone (using the 911 emergency number if that service exists in your area) to get help.
