In traffic engineering, a merge is the point where two streams of traffic travelling in the same direction from multiple roads or in multiple lanes on the same road are required to merge into a single lane. A merge may be a permanent road feature, for example at the end of a dual carriageway, or a temporary feature, common during roadworks.
Signs including Stop, Yield, No Turns, No Trucks, No Parking, No Stopping, Minimum Speed, Right Turn Only, Do Not Enter, Weight Limit, and Speed Limit are considered regulatory signs. Some have special shapes, such as the octagon for the Stop sign, the triangle for the Yield sign, and the crossbuck for railroad crossings.
These signs indicate when a multilane highway is being narrowed, when a passing lane is ending, or where the road is widening or a passing lane starting. Another type of sign is used to indicate central "two-way" left turning lane in center of roadway. Warning signs may also warn of "Highway ends", where the road changes class or type.

All LRMS signs are installed on the 'true left' side of the lane or carriageway, this is determined by the left hand side when facing the increasing direction, The increasing direction of travel is the direction in which positive measurements are made.
Broken lines that are wider and closer together than regular broken lines are called continuity lines. Continuity lines on the left side of a lane denote that the lane is about to end and that motorists must soon merge left. Continuity lines on the right mean that the lane will continue, but traffic may merge into it ahead. [27]
