When are paved roads most likely to be slick?

• A. After a long period of dry weather
• B. During heavy traffic
• C. In the opening minutes of rain
• D. Only during winter weather

Answer: (C)

Paved roads are most likely to be slick in the opening minutes of rain due to the accumulation of dust, oil, and other contaminants on the road surface. When it starts to rain, the water mixes with these substances, creating a slippery film that reduces traction. This is particularly hazardous because drivers may not anticipate the sudden loss of grip, leading to an increased risk of accidents. While it is true that paved roads can be slick after long periods of dry weather, this typically happens over a more extended period. Slick conditions and reduced traction are most pronounced immediately after rain begins, as the water has not yet had a chance to wash away the built-up debris. Heavy traffic does not typically contribute to road slickness—rather, it can sometimes help to clear away some of the surface contaminants. During winter weather, while roads can indeed be slick due to ice or snow, that situation is separate from the specific conditions that occur when rain first starts to fall.
