Why Do Texas Roads Get Slippery When It Rains?

You’ve undoubtedly seen the ominous warning signs on Texas roadways: Slippery when wet. If you’re smart, when you see these signs and it’s raining, snowing, drizzling or foggy outside, you automatically reduce your speed and pay closer attention to your driving. But have you ever asked yourself, “  Why do Texas roads get slippery when it rains?”  After all, asphalt is a coarse material.

The force of rubber tires hitting the tiny pits and grooves that comprise an asphalt roadway creates friction that causes your tires to remain in contact with the road and allows you to maintain good control of the vehicle. When moisture is added to the equation, it fills these pits and makes the road surface smoother. The smoother the surface, the less friction is generated when your tires come in contact with the road. Loss of friction means loss of driver control. In extreme cases, when water completely covers a roadway, a complete lack of friction can occur. This can result in the dangerous phenomenon known as hydroplaning, which causes you to temporarily lose all control of your car. In addition to lack of friction, roads become slick when water mixes with oils, greases and other materials on the road.

If you live in Texas, you need to know  how to drive in adverse conditions. Here are some tips for staying safe when driving in the rain.

Your tires and brakes are the two most critical vehicle components to keep you safe during wet driving conditions. Even if you’re careful and driving slowly, you may skid. If you do, don’t panic. Don’t slam on your brakes or pump them. Simply apply steady, firm pressure to your brakes and steer toward the skid to avoid losing control. If you hydroplane, don’t brake right away. Remove your foot from the gas, grip the steering wheel and then apply light brake pressure.

One important step to ensure your safety while driving in adverse conditions is to make sure your vehicle is well-maintained. If you’re due for a vehicle checkup or a preventive maintenance service,  contact us  at Southwest Auto.
