The code mandates that State Route marker signs feature a shield on a rectangular plate measuring 450 mm by 600 mm, as indicated in the design Plate 1. However, specific materials for fabrication are not detailed in the available documentation.
Route numbers and state names on State Route marker signs should be displayed prominently to clearly identify the route within the state's jurisdiction. Typically, the route number is showcased inside a distinctive shield shape, accompanied by the state name positioned above or below it to ensure easy recognition, aligning with the code's recommendations for clear signage.
The definition plate background must be white with black borders and arrows. For shield signs, the border is black; the upper section inside the border has a bright green background conforming to Indian Standard Colour No. 221, with the state name in white letters over it. The lower section background is white featuring black 'SR' letters and route numbers. Additionally, the back of all signs is painted grey (IS Colour No. 630), and signposts are painted in alternating black and white bands.
At junctions where numbered routes cross or branch from a State Route, the assembly includes mounting the intersecting route’s marker sign ahead of the junction along with the State Route marker on the same post. A definition plate with directional arrows is also attached to indicate route directions, providing clear guidance to motorists as per the specified guidelines.
On roads with curbs, signs should be installed less than 60 cm from the curb edge to ensure visibility and safety. Signs on State Routes must be placed 100 to 150 meters before junctions on the left side approaching the intersection, serving as advance warning. They should also be installed immediately after intersections as confirmation and at other strategic points to direct traffic effectively.
