　　Of all lights we can see red has the longest wavelength, so the scattering is the weakest．That means the red light travels far．In fact, it travels farther on rainy days．

　　Using the red light can help drivers in farther areas sec the lights．It helps drivers stow down or stop in lime．If drivers don't see the red light until they are close, they may not be able to stop the car in time．An accident may happen Red can also excite people．We can act more quickly when we see the color red．In a word, red lights help drivers stop in time and help prevent accidents．
