Bizarrely enough, to legally drive in India you need a driver's license. An International Driving Permit (IDP) is a small booklet which translates your driving license, so you can show people all over the world that someone, somewhere deemed you capable of driving on public roads.
Getting the correct licenses is entirely your responsibility, but we do highly recommend getting an IDP stamped in category A to allow you to drive a 3-wheeled light vehicle. Teams have gone without one in the past but they have risked run ins with the law and perhaps more importantly - voiding any medical cover in the event of a crash.
The requirements to get the illusive category A stamped vary in different issuing countries. The situations are so different in each country, year on year that you may need to investigate into this.
General: One thing to realise is that an International Driving Permit (IDP) is not a stand-alone document, it is a translation of your own license. It's issued by the same organisation that issues drivers licenses, and its purpose is to make your current drivers license valid in other countries. Therefore, to get an IDP with a Category A Stamp to drive a rickshaw in India, you need to have whatever license from your country you need to drive a rickshaw in your own country. For example, if a Rickshaw is classed as a motorcycle in your own country, then you'll need a full motorcycle license to drive a rickshaw in India.
We reserve the right to check any Runner's licenses if they are planning to drive- we would generally do that if you were speeding around like a twat during test driving.
