Lane Ends (MUTCD W4-2 sign)

Lane Ends

warning sign · diamond · yellow

Your lane (or the adjacent lane) ends ahead — traffic must merge into the remaining lane.

Visual breakdown
Yellow diamond reading LANE ENDS MERGE LEFT (or showing converging lane lines).
Shape recognition
Diamond warning; converging lines mirror what the pavement is about to do.
Color recognition
Yellow caution: a lane is disappearing, plan your move early.
Memory trick
The lines pinch together like a funnel — funnel in early, not at the last cone.
Real-world example
In a work zone the right lane closes ahead; experts recommend the zipper merge — use both lanes, then alternate at the merge point.
Common mistakes
Swerving at the last second without signaling, or blocking the ending lane out of spite — both cause crashes and backups.
Quick recall method
Funnel lines = lane disappearing; merge early and smoothly.
