This is the basic pictograph of the upper torso and arms, which denotes a span, with the addition of a stylised right hand. The hand is shown in profile. The right hand is associated with correct or proper conduct. Hence, this is an ideograph for the noun rules.

There is only one extant example of this Indus sign. Unfortunately, Seal M-1919 is damaged, and the inscription is incomplete.
The motif on seal M-1919 is a scene, which includes a tiger with horns, a partly human hybrid female with horns and a tail, and a tree. My interpretation of the motif is that the tiger represents an irate carter. The carter is being restrained by a female authority figure who enforces the rules of the road. The tree element of the motif might depict Vachellia nilotica (babul). The feathery outline of the tiger's horns resembles that of the tree's leaves. It is possible that the body of the cart (as represented by the shape of the tiger's horns) was made from babul timber. Naval Kandwal states that babul can be used to make the bodies of bullock carts¹.
