A yellow diamond sign shows two arrows — one pointing up and one pointing down, with a dark band between them. What does this sign indicate?

DIVIDED HIGHWAY WARNING SIGNS: TWO ARROWS DIVERGING (↑↑ with divider): Divided highway BEGINS — road ahead splits; stay right; the approaching lanes will be separated by a median, barrier, or island; TWO ARROWS CONVERGING (→← or ↑↑ without divider): Divided highway ENDS — the two-direction separated road merges back to an undivided road; oncoming traffic resumes in the opposing lane; DRIVER RESPONSE for divided highway BEGIN: Move to the right; begin looking for the right side of the dividing barrier; watch for vehicles crossing from oncoming direction before the divider starts; DIVIDED HIGHWAY END: Particularly important — drivers coming from an undivided road section and entering the divided highway beginning may mistake the median for a shoulder. Head-on crashes at divided highway endings are a serious hazard.
