How many drivers are typically involved in collisions between two vehicles?

In collisions between two vehicles, typically, two drivers are involved. Each vehicle has one driver, which accounts for a total of two individuals who are directly operating the vehicles during the incident. This scenario aligns with the most common type of vehicle collision, where two vehicles come into contact, resulting in a collision that affects both drivers and their respective vehicles.

While other options suggest involvement of one, three, or four drivers, these do not accurately represent standard vehicle collisions between two vehicles, where the primary focus is on the two drivers directly involved in the crash.
