Final answer:
For safety, it is recommended to engage your left turn signal at least 100 feet before making a turn on a two-lane road in business or residential areas. Exceptions to traffic rules may arise in emergency situations, such as a passenger in labor, where the benefit of prompt hospital arrival could be considered to outweigh the need to adhere strictly to red light laws.
Step-by-step explanation:
When passing on a two-lane road, engage your left signal light at least 100 feet in business or residential areas before making a turn. It is important to signal in advance to alert other road users of your intent to turn or pass, thus ensuring safety on the road. This rule is a part of basic driving regulations that are taught during driver's education. Let's consider a related situation: If there is a pregnant woman in the back seat of your vehicle in labor at 4 am with no other cars around, and you are only 2 miles from the hospital, Rule Utilitarianism (RU) would suggest that the morally good action could be to proceed through the red light to get to the hospital more quickly, provided that doing so does not risk safety. This scenario would be an exception to the general rule due to the urgency and the potential benefits outweighing the typical adherence to traffic laws. Furthermore, the decision to install a new traffic signal can be influenced by various factors such as pedestrian safety, increased traffic due to nearby business development, and special events routing. This exemplifies how traffic regulations and controls are dynamic and respond to the needs of the community.
