No Merge Area Signs are MUTCD compliant (MUTCD W4-5P) and uses an effective message for traffic and pedestrian safety concerns. A No Merge Area Sign is a helpful resource to aid in the protection of the health and safety on roads, and is not an alternative for required protective measures for eliminating or reducing hazards.
Compliance
Section 2C.40 Merge Signs
Option
An Entering Roadway Merge (W4-5) sign with a NO MERGE AREA (W4-5P) supplemental plaque mounted below it may be used to warn road users on an entering roadway that they will encounter an abrupt merging situation without an acceleration lane at the downstream end of the ramp.
A Merge (W4-1) sign with a NO MERGE AREA (W4-5P) supplemental plaque mounted below it may be used to warn road users on the major roadway that traffic on an entering roadway will encounter an abrupt merging situation without an acceleration lane at the downstream end of the ramp.
For a yield-controlled channelized right-turn movement onto a roadway without an acceleration lane, a NO MERGE AREA (W4-5P) supplemental plaque may be mounted below a Yield Ahead (W3-2) sign and/or below a YIELD (R1-2) sign when engineering judgment indicates that road users would expect an acceleration lane to be present.
