Although law mandates insurance policy for 3rd party only but it is strongly advised to buy a comprehensive insurance policy that protects your vehicle from man-made or natural calamities. With comprehensive cover, you can claim from your insurer for accidents or damages caused to your vehicle. In the absence of comprehensive cover, you need to foot the entire bill on your own.
Legally, anyone driving a vehicle should hold a valid driving license for that category. As the owner, it’s your responsibility to ensure that those with a valid driving license are driving your vehicle. Also ensure that no one (including you) drives the vehicle under the influence of alcohol or drugs. If the driver is intoxicated at the time of an accident then insurance company is not liable to compensate the policyholder.
