Who was responsible for the accident involving the small car?

The driver of the small car is identified as responsible for the accident because, in most traffic scenarios, the driver is directly in control of the vehicle's operation. This includes making decisions about speed, direction, and precautionary measures such as following traffic signals and avoiding obstacles. The driver has a legal and moral obligation to ensure the safety of their vehicle, passengers, pedestrians, and other road users.

In contrast, the other roles mentioned, such as the pedestrian, passenger, and bystanders, typically influence the situation but do not hold the same responsibility for safely operating a vehicle. Their actions may impact the scenario, but ultimately, it is the driver's responsibility to navigate the cars safely and effectively. This establishes why the driver of the small car is deemed accountable for the accident.
