Every few hundred metres of Indian road carries a short white stone with a coloured band across the top. Most players glance at it, decide it is furniture, and move on.
It is the most information-dense object on the Indian roadside. It names a town, gives a distance in kilometres, and encodes the class of road you are standing on in a single colour.
The colour code
| Band colour | Road class | What it implies |
|---|---|---|
| Yellow | National Highway | A long-distance corridor. You may be far from any town. |
| Green | State Highway | Inside one state, connecting its own towns. |
| Black or white | Major district road | Local network. A town is not far. |
| Orange | Rural / village road | A village is close — often within a kilometre or two. |
| Blue | Urban or municipal road | You are inside a built-up area. |
The band sits at the top of the stone; the body stays white with black lettering. On newer highways the same colour logic carries onto the larger direction boards.
The colour tells you what kind of road you are on. What kind of road you are on tells you how far you can be from anything.
Use it as a distance clue
This is the part that gets missed. The colour does not narrow the map by itself — no state has its own milestone colour. What it does is tell you how much uncertainty to allow around whatever else you have found.
- Orange band
- A rural connectivity road. These exist to link a village to the network, so the village is close. Pin tight to the nearest settlement you can justify.
- Black or white band
- District road. You are inside a local network, likely within 10 to 20 km of a town of real size.
- Green band
- State Highway — strong evidence you are inside one state, not on a corridor crossing several. Valuable in an India-only round.
- Yellow band
- National Highway. Widen your uncertainty. You could be hundreds of kilometres from the nearest thing you would recognise.
Read the text, not just the colour
The stone carries the next town and the distance to it. On most stones that appears in the state language and in English, which hands you two clues at once — the script confirms the region and the English name locates you outright.
A legible town name is the best possible outcome of an Indian round. It is worth zooming on every stone you pass, and worth walking to one if the mode allows movement.
National Highway numbers
When a stone gives you a highway number, it is worth something. The current scheme is systematic:
- Even numbers run broadly east to west; odd numbers run broadly north to south.
- Numbers generally increase from north to south for east–west routes, and from east to west for north–south routes.
- NH 44 is the spine of the country, running from Jammu & Kashmir in the north to Kanyakumari at the southern tip — the longest highway in India.
- NH 48 links Delhi to Jaipur, Ahmedabad, Mumbai, Bengaluru and Chennai, so it touches most of the western and southern population.
- Three-digit numbers are spurs off the trunk route that shares their leading digits, so NH 148 branches from NH 48 and stays in the same broad region.
Even without memorising routes, the parity rule alone is worth having: an even number on the stone means the road is running east–west, which combined with the sun tells you which way you are facing.
The other roadside text
Milestones are not the only fixed text at the verge.
- Direction boards
- Green with white lettering on national highways, listing several towns and distances at once. Better than a milestone when you can find one.
- Toll plaza signage
- Names the plaza, which is usually named after a village. Frequently lists the operating authority and the highway.
- Government scheme boards
- Public works notices name the district and block, and the district is often the most precise administrative unit you will get all round.
- Bus stop shelters
- Painted with the village or stop name in the state language, and often in English underneath.
Anything bolted to the ground beats anything with wheels.
Where this fails
Two honest limits.
First, the colour scheme is applied by state public works departments, and standards drift. Older stones may predate the current scheme, and a repaint by a local contractor is not always to spec. A milestone colour that contradicts everything else in the frame is a stone that was painted by someone in a hurry.
Second, milestones are a rural and highway object. Inside a city you will see very few, and the clue set shifts to signage, plates and street layout instead.
