This sign means:

• A. Detour ahead.
• B. Two-way traffic ahead.
• C. Merge ahead.
• D. The road ahead is closed to traffic in your direction.

Answer: (D)

A sign showing a barrier across the roadway tells you the road ahead is closed to traffic in your direction. You should not continue straight; slow down and follow any posted detour or alternate route, or turn around if no detour is posted. This differs from Detour ahead (which points to a specific alternate route), Two-way traffic ahead (which indicates traffic in both directions on the same road), and Merge ahead (which shows lanes coming together).
