Step 1: Understanding contributory negligence.
Contributory negligence arises when both parties involved in an accident are negligent, and their combined negligence results in the harm or damage caused. In such cases, each party’s lack of due care contributes to the incident.
Step 2: Application to the given scenario.
In this case, the private bus was coming from the wrong side, which constitutes negligence. Simultaneously, the government bus was being driven rashly and the driver failed to slow down even after noticing the other bus. Thus, both drivers contributed to the collision through their negligence.
Step 3: Conclusion.
Since both parties were at fault, the situation amounts to contributory negligence.
