Public Telephone Sign
Shape: Rectangle or square · Colour: Blue background
A public telephone or emergency call point is available here.
What It Means
While mobile coverage has improved dramatically in India, there are still significant network dead zones on mountain roads, deep rural areas, and in some valleys. Public telephone signs mark call points — these may be traditional payphones or NHAI/NHRIP emergency call boxes installed at intervals on national highways. In an emergency without mobile signal, these are lifelines.
📍 Where You'll See It
At highway patrol points, NHAI toll plazas, service areas, and in areas with known mobile dead zones.
✅ What You Must Do
In an emergency without mobile signal, look for this sign. NHAI emergency call boxes connect directly to the nearest patrol post.
⚠️ Common Mistake
Assuming mobile phones work everywhere in India. Several highway sections, especially in the Northeast and Himalayan regions, have no coverage for kilometres at a stretch.
⚖️ Legal Note
No violation. Emergency call boxes on NHAI roads are free to use.
