What is the first thing you should do if you are involved in a collision?

In the event of a collision, the foremost priority is to stop and check for injuries. This action is crucial because the health and safety of everyone involved, including any pedestrians, are of the utmost importance. Assessing injuries allows you to provide necessary assistance and, if required, contact emergency services for medical help.

After ensuring that everyone is safe and addressing any injuries, other important steps can follow, such as exchanging contact details with the other parties involved and notifying your insurance company. However, these should only proceed once it is confirmed that there are no serious injuries that require immediate attention.

The other options, while relevant in the overall process after an accident, do not address the immediate health and safety concerns that must come first in such situations.
