The roadways of Southern California are almost always packed – not just with cars, but with joggers, cyclists, dog-walkers, scooter-riders and the like. Drivers must pay extremely close attention to their surroundings but sometimes a split second of inattention or distraction can spell tragedy. In some situations, a pedestrian may not follow traffic rules or a cyclist may dart out into an intersection. In any case, when vehicles and non-vehicles collide in L.A., the results can be injury, death or criminal charges.
