Left Lane Ends Signs are MUTCD Compliant (MUTCD W4-2L) and alert road-users that they should prep for their lane to end and merge right. Left Lane Ends Signs are useful devices to help display official regulations and provide mandatory information to drivers and pedestrians on both private and public roadways.
Compliance
Section 2C.42 Lane Ends Signs
Guidance
The LANE ENDS MERGE LEFT (RIGHT) (W9-2) sign or the Lane Ends (W4-2) sign should be used to warn of the reduction in the number of traffic lanes in the direction of travel on a multi-lane highway.
A Merge sign may also be installed on the side of the entering roadway to warn road users on the entering roadway of the merge condition.
Option
The RIGHT (LEFT) LANE ENDS (W9-1) sign may be used in advance of the Lane Ends (W4-2) sign or the LANE ENDS MERGE LEFT (RIGHT) (W9-2) sign as additional warning or to emphasize that the traffic lane is ending and that a merging maneuver will be required.
On one-way streets or on divided highways where the width of the median will permit, two Lane Ends signs may be placed facing approaching traffic, one on the right-hand side and the other on the left-hand side or median.
Guidance
Where an extra lane has been provided for slower moving traffic, a Lane Ends word sign or a Lane Ends (W4-2) symbol sign should be installed in advance of the downstream end of the extra lane.
Lane Ends signs should not be installed in advance of the downstream end of an acceleration lane.
