Citizens of India have to apply for tourist visas but this visa is issued gratis. The same applies to Uruguayans visiting India. This is because of the reciprocity that India shares with a lot of countries. The same applies to India-Argentina as well.

There is no regular long distance train service. The most usual means of public transport is the bus inside Montevideo inner buses and from Montevideo to other main cities of the country.
There are many buses running from the Brazilian cities of Porto Alegre, SÃ£o Paulo and Rio de Janeiro. Bus service is very extended and there are many services that run from Montevideo to different cities across the country. Terminal Tres Cruces (http://www.trescruces.com.uy), Agencia Central and Terminal Ciudad Vieja are the three main hubs. Travel by bus is very safe. International Services are available to Sao Paulo, Porto Alegre, Brazil, most of the Argentinian Provinces Buenos Aires, Cordoba, Mendoza, Entre Rios, Asuncion Paraguay and Santiago de Chile Chile. The service is catered and buses have an outstanding level of service, much better than the average European service.
Bus service to Buenos Aires has been made much longer due to the ongoing conflict between Uruguay and Argentina over a cellulose plant built on the Uruguayan side of the border at Frey Bentos. Because of the conflict the bridge has been blocked, and will remain blocked until the conflict is resolved. For this reason it's much better to take the ferry from Colonia rather than do the whole trip via bus.
The highways are in good shape. Speed limit is 90 km/hour to 110 km/hour on most of them but it's not enforced.The main highway is the one that goes from Montevideo to Punta Del Este main tourist city of Uruguay, it is double lane from both sides. However this is strange since most of the highways are single lane and therefore you should take precautions when driving long distances a "long distance" in Uruguay is 500 km max, trying to pass another car. Always keep your distance from the car in front of you.Signaling is good enough. Take notice of the emergency phone numbers on the highways and keep them noted. Uruguay is not a dangerous country, but since it is mostly agricultural if your car breaks down it can take you a while for you to walk to a phone. It is recommended to carry a cell phone with you. Ancel is the state company and the main provider. In Uruguay drive on the right.You should have the "carta verde" licence to drive in Uruguay, you can find it in the embassy. The legal limit of alcohol contentration is 0.03 % 0.0% for trucks,taxis and bus drivers
