Dashcam video captured the moment power lines crashed down onto vehicles during a dust storm in Las Vegas. What to do if power lines fall on your car: Stay in your vehicle and put your hands on your lap. If you step out, you could be electrocuted because your body would complete the circuit between that electrified car and the ground. Call 911 with a cell phone and prevent others from approaching. #severeweather #wind #duststorm #vegas #thunderstorm #caughtoncamera #dashcam #weather #accuweather
