This is the verb to drive, but with mirrored orientation. An antonym of drive is to slow. Hence, the mirrored version of Mahadevan's sign number 1096 is an ideograph for the verb to brake or to slow.

Comment:
In both inscription L-5 and inscription M-198, the verb to brake is followed by the verb to drive. This gives us the adjective stop-start. In M-198, it is used to describe the process of bartering.
