When driving in near-freezing temperatures on a highway surface that appears wet, noticing that tires of preceding vehicles have stopped throwing water spray indicates that black ice has formed, requiring the driver to reduce speed to a crawl rather than applying the standard one-third speed reduction for wet pavement.
Answer: Answer
Answer
True, because the absence of tire spray in freezing temperatures signals black ice formation, which mandates slowing to a crawl.
The statement correctly describes both the physical indicator of black ice and the appropriate speed adjustment. When the road appears wet but tire spray disappears at or near freezing temperatures, water on the roadway has frozen into a thin, clear sheet of ice. Because ice offers virtually no traction, the driver must reduce speed to a crawl rather than relying on the standard one-third reduction used for liquid water.
