This is a question that comes up from time to time for our subject matter specialists. Today, we have the full, extensive explanation as well as the answer for everyone who is interested!
Roads are most slippery when it rains after a dry spell because oil and dirt haven’t washed away. Your tires don’t grip as well on oil-slicked roads, so slow down when the first rain hits. California’s Department of Motor Vehicles recommends driving five to 10 miles per hour slower on wet roads.
Are roads most slippery in the first 15 minutes of rain?
In fact, troopers said the first 15 minutes of light rain is the most dangerous time to be driving because oils make the road exceedingly slippery. “As you can see, all of these represent a traffic crash and there’s so many at this point in time, because of the rain that we have,” Trooper Watson showed.
What part of a rainstorm will lead to extremely slippery roads?
Solution: Roads are most slippery at the beginning of rain storms due to oil and dirt from traffic. By the end of a rain storm, the oil and dirt are more likely to have been washed off the roadway. Additionally, rain is not the only factor that can contribute to slippery roadways – and not even the most dangerous.
What is the most dangerous time to drive in the rain?
If the rain has just started to come down and you can push your departure time back by a few minutes that is highly recommended, as the first 15 minutes of rain is the most dangerous time to drive. During the beginning of a rain, water mixes with oil dripped on the pavement from vehicles, making roads extra slick.
At which of the following times are the roads typically most slippery?
Driving in Rain or Snow

What is the most dangerous part of a rainstorm?
Safety experts say that the most dangerous time to be on a wet road is the first 10 minutes of precipitation, be it rain or snow. When the rain or snow has just started to land on the highway it’s mixing with oil on the surface of the road in slippery pools, a perfect recipe to lose traction and dangerously hydroplane.
What causes the road to become the most slippery in the first 10 15 minutes of a rainstorm?
Pavement can become very slippery within the first 10 to 15 minutes of a rainstorm because the rain causes oil in the asphalt to rise to the surface of the road. This problem becomes even worse in hot weather. The heat combined with the water causes more oil to rise to the road surface.
Why is asphalt slippery wet?
When it rains, the water on a road causes a loss of friction. As tires move over a wet surface, the water fills in the tiny pits in the road surface, effectively smoothing out the surface. As a result, the normal heat and friction created is decreased, leading to a surface that is more slippery than when dry.
What temperature are icy roads most slippery?
Thus, ice is most slippery when temperatures are near freezing (26-32F) and is much less slippery when temperatures reach the single digits and below. So if the air temperature is just below freezing and ice is on the roadway, extra care is warranted.
At what speed does hydroplaning occur?
Vehicle speed – always slow down when it’s wet. Hydroplaning can occur at any speed under the right combination of conditions, but some sources define higher speeds as over 40 mph.
Where are roadways the most slippery?

How many car lengths is a safe distance?

How many car lengths is 3 seconds?
How to Measure a Safe Following Distance. Many drivers follow the “three-second rule.” In other words, you should keep three seconds worth of space between your car and the car in front of you in order to maintain a safe following distance.
