Answers with Explanation:
Question # 1: Type of Law.
As the man goes above the described speed limit, he broke the law and committed a crime. Therefore, this is a criminal law. The punishment for speeding increases the faster the person is driving above the speed limit.
Question # 1: Source of the Law.
The law is in a written form, describing to public what is allowed and what action is prohibited. Hence, the source is statute.
Question # 3: Purpose of the law.
The action of speeding means you are going faster than the recommended speed for that road. This means that you can injure yourself as well as others in an accident. Thus this law is intended as measure to ensure public safety. For example, the man was going at 67 miles per hour, that is more than 20 miles above the speed limit. At this speed reaction time is very small and even a minor mistake can turn into a deadly accident.
