I was curious if an expat wants to drive a vehicle in say Mumbai does he/she need an indian driving license or say a US license will work for short periods (less than 2 weeks) as is the case for EU.

If you believe that driving licenses in India are a joke and the system is corrupt please avoid pontificating and responding to my request. The question is intended to determine the correct way to get vehicle driving privileges in India when the chauffeur is not available.

Thx.
