Wаlker, а pedestriаn, started nоrth acrоss the street in a clearly marked nоrth-south crosswalk with the green traffic light in her favor. Walker was in a hurry, and so before reaching the north curb of the street she cut to her left diagonally across the street to the east-west crosswalk and started to cross it. Just after reaching the east-west crosswalk the traffic light turned green in her favor. She proceeded about five steps farther across the street to the west in the crosswalk when she was struck by a car approaching from her right that she thought would stop, but did not. The car, driven by Driver, 81 years old, failed to stop after seeing that the traffic light was red against him. Walker had a bone disease, resulting in very brittle bones, that is prevalent in only 0.02% of the population. As a result of the impact Walker suffered a broken leg and the destruction of her family heirloom, a Picasso original painting that she was taking to her bank for safe-keeping. The painting had been purchased by Walker’s grandmother for $750 but was valued at $500,000 at the time of the accident. Walker filed suit against Driver. Driver’s attorney has alleged that Walker violated a state statute requiring that pedestrians stay in the crosswalks, and that if Walker had not violated the statute she would have had to walk 25 feet more to reach the impact point and therefore would not have been at a place where she could have been hit by Driver. Walker’s attorney ascertains that there is a statute as alleged by Driver, that his measurements are correct, that there is a state statute requiring observance of traffic lights, and that Driver’s license expired tow years prior to the collision. The violation of the crosswalk statute by Walker should not defeat her cause of action against Driver because:

Pаsser wаs driving his pickup truck аlоng a lоnely rоad on a very cold night. Passer saw Tom, who was a stranger, lying in a field by the side of the road and apparently injured. Passer stopped his truck, alighted, and, upon examining Tom found him to be intoxicated to the point of having passed out, and noted that he was now in danger due to being exposed to the cold. However, Passer returned to his truck and drove away without making any effort to help Tom. Tom remained lying at the same place and was later injured when hit by Traveler’s vehicle. Traveler did not see Tom prior to hitting him and had only run over him because Traveler had become drowsy and inattentive and had thus veered off the road and into the field where Tom was lying. If Tom asserts as claim against Passer for damages for his injures will Tom prevail?
