Understanding Indian Road Milestones and Colour Codes
Milestones are important markers on roads that provide crucial information to travellers, primarily indicating the distance to upcoming destinations. In India, these milestones use specific colour codes on their tops to signify the type of road you are travelling on. These colour codes help drivers understand the highway network and navigate effectively across the country.
Decoding the Yellow and White Milestone Colours
When you see a milestone in India with a yellow colour painted on the top section and white on the bottom section, it serves as a clear indicator. This particular colour combination is reserved for a specific type of road in the Indian road network.
- The vibrant yellow top band immediately catches the eye.
- The white bottom section typically contains text indicating the destination and distance.
- This combination is universally recognized in India for a particular category of highways.
The presence of a yellow and white milestone means you are currently on a National Highway. National Highways are the major arterial roads connecting states and important cities across India. They are managed and maintained by the National Highway Authority of India (NHAI) or state public works departments.
Other Milestone Colour Codes in India
Besides the yellow and white for National Highways, other colour combinations are used for different road categories:
- Green and White: Milestones with a green top and white bottom indicate you are on a State Highway. State Highways are managed by state governments and connect important cities within a state.
- Blue or Black and White: Milestones with a blue or black top and white bottom usually signify a Major District Road or other important district roads. These roads are vital for connecting areas within a district.
- Orange and White: Milestones with an orange top and white bottom are typically found on Rural Roads, connecting villages and rural areas. These are often built under schemes like the Pradhan Mantri Gram Sadak Yojana (PMGSY).

Additional Information on Indian Road Network
The Indian road network is vast and is categorized into different classes based on their importance and management. Understanding these categories helps in planning travel and logistics.
- National Highways (NH): Form the backbone of the Indian road network, connecting major cities and states. Managed by NHAI or state PWDs. Identified by yellow-top milestones.
- State Highways (SH): Important roads within a state, connecting district headquarters and important towns to NHs. Managed by state PWDs. Identified by green-top milestones.
- District Roads: Roads within a district, connecting district headquarters with other towns and rural areas of the district. Managed by the District Administration or PWD. Major District Roads are identified by blue/black-top milestones.
- Rural Roads: Roads connecting villages within a district or block. Managed by Panchayati Raj Institutions or state rural development agencies. Identified by orange-top milestones.
Recognizing these milestone colours is a simple yet effective way to know which type of road you are currently using in India's extensive road network.
