The spring and summer months often see regular rainstorms. Precipitation helps keep the soil healthy and allows plants to grow. It can cut through the summer heat or help dissolve the last remaining snow in early spring. Rainstorms can also increase the chances of a major wreck.
Drivers can’t necessarily avoid traveling during rainstorms because they are so common. That being said, they may need to shift their driving practices to avoid increased crash risk. Contrary to what people might assume, rainstorms are relatively dangerous and can increase the risk of a car wreck.
What makes a rainstorm so dangerous for motorists?
1. Wet pavement
According to federal crash data analyzed by the Department of Transportation Road Weather Management Program, wet pavement is the top safety hazard that contributes to weather-related collisions.
Approximately 75% of all weather-related car crashes occur when the pavement is wet. That may be during a rainstorm or even after active precipitation ends. Wet pavement affects vehicle traction, increases stopping distance and exacerbates the risk of drivers losing control of their vehicles.
2. Hydroplaning
When rain comes down heavily or for hours, standing water may develop on road surfaces. Even relatively shallow puddles are a risk for drivers. Those with worn or under-inflated tires are particularly vulnerable to hydroplaning.
Hydroplaning occurs when water disrupts tire traction. Drivers may not be able to maintain their speed or their control over their vehicles when they hydroplane.
3. Decreased visibility
Sometimes, rain is merely a light sprinkle. It barely provides adequate lubrication for the windshield wipers as they move. Other times, rainstorms create torrential downpours. The amount of precipitation is significant, and even the fastest wiper setting may not be adequate to keep the windshield clear.
Motorists driving in the rain may have a hard time monitoring their surroundings. They may have not have a lot of time to react when another driver stops short or a pedestrian steps out into the street. Slowing down, increasing following distance and focusing more on safety and help people avoid motor vehicle collisions during rainstorms.
Understanding the factors that contribute to motor vehicle collision risk can help people avoid causing crashes. Those affected by rain-related collisions may have a valid reason to hold other drivers accountable for unsafe behavior in predictably dangerous weather.
