Washington Written Drivers Permit Practice Test

Roads are most slippery when it first starts to rain because the water mixes with oil and dirt on the road surface, creating a slick surface. This can make it easier for vehicles to lose traction and potentially skid. It is important to drive with caution during this time to reduce the risk of accidents. While other weather conditions like a sunny day, a windy day, or a foggy day may also present challenges, they do not inherently make the roads as slippery as when it first starts to rain.
