A driver travelling at the speed limit on a country highway at night with headlights on low beam is not negligent merely because the stopping distance exceeds the seeing distance, where conditions are fine and the driver is required to dim headlights for oncoming traffic. Where a collision with an animal on the road is unavoidable given the physics of stopping distance versus visibility, the driver is not negligent even if not keeping a proper lookout. A plaintiff's failure to take adequate precautionary action after observing multiple warning signs of danger ahead constitutes contributory negligence but does not necessarily break the chain of causation so as to relieve a negligent defendant of all liability.
