Why Los Angeles Roads Get Slippery When It Rains
The recent rains in Southern California from Tropical Storm Hilary made for dangerous road conditions in much of the region. While a lot of Southern Californians still can’t drive when roads get wet, there are actual reasons why LA roads get so treacherous in slick conditions, Spectrum News explains.
The Impact of Rain on Los Angeles Roads
When it rains in Los Angeles, the roads become a hazard for drivers. The combination of oil, dirt, and debris that accumulate on the roads during dry spells creates a slippery surface when it gets wet. This phenomenon is known as the “first rain effect.”
During extended periods without rain, oil and other fluids from vehicles build up on the road surface. When it finally rains, these substances mix with water, creating a slick and hazardous surface. The accumulated oil and debris reduce the friction between the tires and the road, making it difficult for drivers to maintain control of their vehicles.
The Role of Geography
Los Angeles’s unique geography also contributes to the slippery road conditions during rainstorms. The city is surrounded by mountains and hills, which can cause water to flow downhill rapidly. This rapid flow of water can lead to flooding and pooling on the roads, making them even more treacherous.
In addition to the natural topography, Los Angeles has an extensive network of storm drains and channels designed to divert rainwater away from populated areas. However, during heavy rain, these drainage systems can become overwhelmed, leading to localized flooding and further exacerbating the slippery road conditions.
The Need for Caution
Given the hazardous conditions that arise when it rains in Los Angeles, it is crucial for drivers to exercise caution and adapt their driving habits accordingly. Here are some tips to stay safe on the road during wet weather:
1. Slow Down
Reducing your speed is essential when driving on slippery roads. It allows you to have better control over your vehicle and gives you more time to react to any potential hazards.
2. Increase Following Distance
Leave more space between your vehicle and the one in front of you. This extra distance provides a buffer zone and allows for a longer stopping distance, reducing the risk of rear-end collisions.
3. Avoid Sudden Maneuvers
Make smooth and gradual movements when steering, accelerating, and braking. Sudden actions can cause your vehicle to skid or lose control on the slippery surface.
4. Check Your Tires
Ensure that your tires are properly inflated and have sufficient tread depth. Bald or underinflated tires are more prone to hydroplaning, where the tires lose contact with the road surface and glide on a layer of water.
5. Use Your Lights
Turn on your headlights to improve visibility for yourself and other drivers. It also helps others see your vehicle in adverse weather conditions.
The Importance of Preparedness
While Los Angeles may not experience rain as frequently as other parts of the country, it is essential for residents to be prepared for wet weather conditions. This includes having a well-maintained vehicle, checking weather forecasts before heading out, and staying informed about road closures or hazardous conditions.
By taking the necessary precautions and being mindful of the unique challenges posed by rain in Los Angeles, drivers can help reduce accidents and ensure their safety on the road.
Remember, it’s not just about your own driving skills but also about being considerate and cautious towards other drivers. Together, we can navigate the slippery roads of Los Angeles during rainy weather.
