For those willing to brave Delhi's congested roads, driving is, in principle, on the left and foreign drivers must be over 18 and in possession of an International Driving Permit. Beyond that, there are few rules that are either adhered to or enforced. The consensus is that it is far safer to use taxis or hire a car with a driver for longer journeys. National Highways are designated by a number.

Those intending to take their own car to India must obtain a carnet from one of the international motoring associations (such as the RAC or the AA) before entering the country. This document represents an undertaking that the car will not remain in India for more than six months. Most European motor insurance policies do not extend to India and motorists are advised to seek cover from an Indian insurer, as insurance is compulsory.
