So last night my sister's car would not start when she was at work and so called my dad and i to go look at it and/or pick her up. This was at 11:10, we live about 20miles from where she works. So me and my dad head over there in his truck a dodge 2500 with him driving. The route there is mainly back country roads with little traffic at 11pm on a friday night. About 5mins in to the drive were doing the speed limit of 45mph on a pretty narrow country road and there is an on coming car with high-beams on not much you can do about that apart from stay in your lane give the other guy is kinda blinding you(my dad flashed his high beams once but the guy kept his on). What we didn't see was walking with traffic on the right side of the road in the lane(i.e. left of the white line) was a lady wearing dark cloths. So right as we pass the other car we end up hitting this lady in our lane with the passengers side mirror. As soon as we hit her we slammed on the breaks, we were just passing a side road so quickly backed up in to the side road. We then went over to her, i called 911 as my dad was w/ the lady who was sitting up by the time we got there. At this point we are in the right hand lane on the side, after giving info to 911 we were waiting for emt/fire/leo to show up and then had cars coming down the road. I had in my pocket my SF G2ZL as i always do and so i had that out and shinning down the road towards the on coming cars to ensure that we didnt get hit not wanting to move the lady in case of broken bones. The first car that came down the road noticed the light right away and slowed down and passed on the left side slowly. However another car came not paying attention or speeding or both, either way didn't notice the bright light flashing towards them in their lane untill they were 40ft away. At which point they slammed on the brakes/swerved in to the other lane and even then passed us doing at least 30, but i guess thats still better then them hitting us. To make a long story shorter the fire/emt's and leo's showed up about 10min after the accident happened, they look at the lady she refused treatment and seamed to be alright, the mirror she was one of the bending ones so it probably absorbed alot of the impact. The lady said how she had been drinking and then on her drive home(drunk) she ran out of gas and thats why she was walking on the road. The trooper said how because she was on the side of the road there would not be charges which we kinda figured. The trooper did say with how inebriated she was if the accident happened and she was in the center of the road and still was ok he would have arrested her. So although it sucks we have to buy a new mirror were much more relieved that she was alright, although i cant imagine the bruised shoulder she will have waking up today. Anyhow my big take away from the event: Carry a flashlight. If i didnt have my SF on me there is little doubt in my mind that the speeding car would have more then likely hit that lady again and me/my dad with her.
