“ 16. Negligence means failure to exercise required degree of care and caution expected of a prudent driver. Negligence is the omission to do something which a reasonable man, guided upon the considerations, which ordinarily regulate conduct of human affairs, would do, or doing something which a prudent and reasonable man would not do. Negligence is not always a question of direct evidence. It is an inference to be drawn from proved facts. Negligence is not an absolute term, but is a relative one. It is rather a comparative term. What may be negligence in one case may not be so in another. Where there is no duty to exercise care, negligence in the popular sense has no legal consequence. Where there is a duty to exercise care, reasonable care must be taken to avoid acts or omissions which would be reasonably foreseen likely to caused physical injury to person. The degree of care required, of course, depends upon facts in each case. On these broad principles, the negligence of drivers is required to be assessed.
