After reading your query, I would like you to know that
Death caused by a negligent act can be booked under section 304(A) of IPC. The punishment for the accused includes a minimum of two years of imprisonment and/or paying of fines.
There can be various scenarios wherein the liability may fall on the car owner
Case 1 - When the Car Owner is not present during the accident
if the car owner is not present during the accident, usually the liability does not fall on them. Whether it’s a case of negligent driving or a case of drunken driving, the onus is on the person driving. However, the car owner can be liable if the car was not in a roadworthy condition.
Case 2 - If the Car Owner is present during the accident
The car owner (the one in whose name the vehicle is registered) is not liable as long as he has not instigated the driver to drive fast and rashly. If the owner of the car has actively instigated the driver to drive rashly or consented to the accident, then the car owner can be liable.
Case 3 - If there exists a master-servant (driver/employer)relationship
in the case that the car owner has hired the driver i.e. they share a driver (servant) and master (employer) situation, then the car owner may be vicariously liable to the acts of the driver. This will only be applicable when the car driver commits the accident in the course of his employment.
If the accident took place, not in the course of employment, the car owner will not be held liable
Hope this helps!
