Question

when you see this black and yellow sign, it means:
detour to the right because of road construction.
slow down because the road ahead changes direction at an extreme angle.
the road to the right is for one-way traffic only.
there is a cross road ahead on your right.

Explanation:

Identify the sign type and color

The image shows a yellow, diamond-shaped warning sign (cropped to a rectangle here) featuring a sharp horizontal arrow pointing to the right. Yellow and black signs indicate warnings about road conditions ahead.

Analyze the meaning of the arrow

A horizontal arrow pointing sharply at a 90-degree angle indicates a sharp turn or an extreme change in direction ahead, requiring drivers to reduce their speed significantly.

Evaluate the given options

• Option 1 (detour) is incorrect because detour signs are typically orange (construction).
• Option 2 (slow down because the road ahead changes direction at an extreme angle) matches the definition of a sharp turn warning sign.
• Option 3 (one-way) is incorrect because one-way signs are black and white rectangles.
• Option 4 (cross road) is incorrect because cross road signs use a "+" symbol.

Answer:

• detour to the right because of road construction.
• slow down because the road ahead changes direction at an extreme angle. (Correct answer)
• the road to the right is for one-way traffic only.
• there is a cross road ahead on your right.
