This will support your case, I think.
General Manager, B. E. S. T. Undertaking, Bombay v. Mrs. Agnes
In this case, a public utility transport service run by the Bombay Municipal Corporation owned a number of buses and employed a staff, including bus drivers, for conducting the service. The deceased driver finished his work for the day. After leaving the bus in the depot, he boarded another bus to go to his residence. The bus collided with a parked lorry. As a result of the collision, he was thrown out onto the road and got injured. Later, he died in the hospital. His widow filed an application in the Court of the Commissioner for compensation.
The Supreme Court stated that, in view of the long distances to be covered by the employees, the Corporation, as a condition of service, provides a bus for collecting all the drivers from their houses so that they may reach their depots in time and to take them back after the day's work. They are given that facility as a right because the efficiency of the service demands it. The Court observed that:
“The employment does not necessarily end when the 'down tool' signal is given or when the workman leaves the actual workshop where he is working. There is a notional extension at both the entry and exit by time and space. The scope of such extension must necessarily depend on the circumstances of a given case. The doctrine of notional extension of employment developed in the context of specific workshops, factories, or harbors equally applies to such a bus service provided to employees to get to the job on time and reach their home without further strain, contributing to their overall efficiency. The bus service is used as a privilege and matter of right. Their workplace gets notionally extended by virtue of this service.”
The Supreme Court held that when a driver, when going home from the depot or coming to the depot, uses the bus, any accident that happens to him is an accident in the course of his employment.
