Final answer:
Parking is illegal in several situations like blocking driveways, fire hydrants, in no-parking zones, etc. There are exceptions in emergencies that may justify breaking traffic laws, such as a medical emergency with a pregnant woman. Discrimination based on skin color when pulling over drivers is also illegal.
Step-by-step explanation:
It is illegal to park your vehicle under various conditions that violate traffic laws and regulations. Some common scenarios where parking is prohibited include parking in front of fire hydrants, blocking driveways, in no-parking zones, in front of a public or private driveway, within certain distances of intersections, crosswalks or stop signs, on a sidewalk, in handicapped spaces without the proper permit, and on the roadway side of another parked vehicle (double parking).
Exceptions can occur in emergency situations, which may provide legal defense for actions that would typically break traffic laws, such as driving through a red light at 4 am with a pregnant woman experiencing contractions in your vehicle, and you are en route to the hospital. Such circumstances could be analyzed under the principle of utilitarianism, where the greatest good for the greatest number may sometimes warrant breaking a traffic rule. Nonetheless, these are special scenarios and don't necessarily provide a blanket exception to parking laws.
It's also important to mention that discriminatory practices such as pulling over drivers because of their skin color is an illegitimate use of governmental authority and violates civil rights. Safety is always a top priority, and drivers should adhere to the rules, unless extraordinary circumstances dictate otherwise, and even then, caution and judgment are paramount.
