Road Narrows Signs FAQ
What does a road narrows sign mean?
A road narrows sign (MUTCD W5-1) is a yellow diamond warning that the roadway ahead becomes narrower — both sides come in. Drivers should slow down, stay centered in their lane, and watch for oncoming traffic in the tighter space ahead.
What is the difference between a road narrows sign and a narrow bridge sign?
A Road Narrows sign (W5-1) warns that the whole roadway gets narrower ahead, while a Narrow Bridge sign (W5-2) warns specifically that a bridge ahead is narrower than the road leading to it. The symbols differ — road narrows shows the pavement edges angling in; narrow bridge shows a bridge outline. See our Narrow Bridge Signs.
Is a road narrows sign the same as a narrow road sign?
Yes. Narrow road sign and roadway narrows sign are common names for the same W5-1 sign. It warns of a reduction in the width of the traveled roadway ahead.
Where is a road narrows sign used?
It is posted in advance of a point where the pavement or number of usable lanes narrows — for example approaching an older section of road, a construction taper, or a rural stretch that tightens. It gives drivers time to reduce speed before the narrower section.
What shape and color is the road narrows sign?
It is a standard yellow diamond warning sign with a black symbol showing the road edges coming together. A fluorescent-orange version is used in temporary traffic control and work zones.
What is the difference between road narrows and lane ends?
Road Narrows (W5-1) means the overall roadway gets narrower but the same number of lanes continues, while a Lane Ends sign (W4-2) means one lane actually ends and traffic must merge. Road narrows asks you to tighten up; lane ends asks you to merge.
What sizes are road narrows signs, and can I customize them?
Common sizes are 30x30 and 36x36 inches. Signs are printed on rust-proof .080" aluminum with reflective sheeting, and larger or orange work-zone versions are available on request.
