Final answer:
True, the roadway is most slippery during the first few minutes of rain due to a mix of water with oil and dirt on the road surface. Therefore , the correct answer options is true.
Step-by-step explanation:
The statement is true; the roadway is indeed most slippery during the first few minutes of rain. When rain first starts to fall, it mixes with the oil and dirt on the roadway that hasn't been washed away yet creating a slick surface.
This mixture reduces the traction of tires on the road and can lead to increased danger of skidding or hydroplaning. Additionally, because the water has not had enough time to wash away the accumulated materials, the slippery effect is much more pronounced at the beginning of a rainfall as compared to after the rain has continued for some time.
