A. Roadways
Q1. Importance of Road Transport
Q1. “Road transport plays a vital role in the economic development of India.”
Justify the statement by giving any three reasons.
Answer:
Road transport is crucial for India because:

2. Short and medium distances: For short and medium distances, especially within cities, towns and villages, roadways are more economical and quicker than railways.
3. Linking other modes: Roadways act as a feeder to railways, ports and airports by carrying goods and passengers from their starting point to these terminals and vice versa.
