W2-2 (Intersection Warning - Side Road) is an official MUTCD traffic sign designation within the warning sign family. Standard vector graphics are published by FHWA under Standard Highway Signs.
10 (18 × 18 in — Left arrow, 18 × 18 in — Right arrow, 24 × 24 in — Left arrow, 24 × 24 in — Right arrow, 30 × 30 in — Left arrow, 30 × 30 in — Right arrow, 36 × 36 in — Left arrow, 36 × 36 in — Right arrow, 48 × 48 in — Left arrow, 48 × 48 in — Right arrow)
W2-2 warns of a side road joining the road ahead. The direction shown in the symbol is important because a side-road warning is different from the W2-1 crossroad symbol, which depicts a road crossing, or the W2-4 T-intersection warning.
What to verify
Compare the approaching roadway geometry with the left- and right-oriented artwork variants. Any decision about need, location, or spacing should be based on the actual intersection and the governing MUTCD provisions—not a generic sign-code lookup alone.
For further context, read the related MUTCD guide and compare the official FHWA MUTCD. This independent reference does not replace engineering judgment or applicable state requirements.
