In which phase of intensive rain is the asphalt roadway more slippery?

Description

Topic 8 of teaching material 2.2.2. of Annex No. 1 to the Regulation of the Minister of Transport, Construction and Maritime Economy of 13 July 2012 on the training of persons applying for driving licenses, instructors and lecturers (Journal of Laws of 2012, item 1019, as amended).

Explanation

Correct answer: Initial phase.

At the beginning of rainfall, water mixes with debris on the road surface, such as dust, dirt, tyre residue, and operating fluids. This creates a very slippery layer that significantly reduces tyre grip before it is washed away by further, heavier rain. This is why the first few moments of rain are the most dangerous for drivers.
