Additional Details

MUTCD Section 2C.31 Merge Signs (W4-1, W4-5)
Option: A Merge (W4-1) sign (see Figure 2C-6) may be used to warn road users on the major roadway that merging movements might be encountered in advance of a point where lanes from two separate roadways converge as a single traffic lane and no turning conflict occurs.
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.

Guidance: The Merge sign should be installed on the side of the major roadway where merging traffic will be encountered and in such a position as to not obstruct the road user's view of entering traffic.
Where two roadways of approximately equal importance converge, a Merge sign should be placed on each roadway.
When a Merge sign is to be installed on an entering roadway that curves before merging with the major roadway, such as a ramp with a curving horizontal alignment as it approaches the major roadway, the Entering Roadway Merge (W4-5) sign (see Figure 2C-6) should be used to better portray the actual geometric conditions to road users on the entering roadway.
The Merge sign should not be used where two roadways converge and merging movements are not required.
The Merge sign should not be used in place of a Lane Ends sign where lanes of traffic moving on a single roadway must merge because of a reduction in the actual or usable pavement width (see Section 2C.33).
