AMDifficulty 1/5

After a dry period, rain begins falling on a dusty, greasy road without snow or ice. Can the danger increase?

Correct answer

Yes, water mixed with residue can reduce grip.

Yes: water mixing with residue can form a slippery film and reduce grip. Slow down, increase following distance and avoid abrupt movements. Initial light rain does not mean low risk, nor is it always more dangerous than every later rainfall. Snow chains are not the remedy for a merely wet road.
