This happen tonight, so I'm blasting up 3rd street (parkslope) and it's 2 am. I'm riding along side a buddy of mine and we are trying to beat the light and all of sudden he pulls back and I mash on much harder than before. When at that moment I see the lights of a Verizon truck a 6wheeler, I try to skid but we are both going to fast. So at that point I fall the my side and slide on the concrete and he swerves, but the back of his truck hits my rear and spins me and pulls my bike from my feet that were still strapped in and speeds off. Luckily everything was ok, and all I have is a cut elbow, thankfully, all this the night before I graduate lol.
