Final answer:
Passing on the right is not permitted when it is unsafe, illegal, or the current lane conditions do not allow for safe passing. This is explained through various scenarios, including everyday traffic situations and moral dilemmas.
Step-by-step explanation:
Passing on the right is not permitted when traffic laws or road conditions make it unsafe or illegal. This typically includes situations where the right side is not designated for passing, the lane is ending, or it's an unimproved shoulder of the road. For example, when driving behind a slower-moving vehicle, as in the case with Peter and the elderly driver, passing on the right would generally be permitted only if there are multiple lanes in the same direction and the lane being used for passing is a valid travel lane, not a bike lane or parking lane, and it is safe to do so. However, Peter's behaviors such as honking and tailgating are not safe or recommended.
The scenarios presented portray ethical dilemmas and illustrate the concept of moral judgments where actions are considered obligatory, permissible, or forbidden. The first scenario would likely consider flipping the switch as morally obligatory to minimize harm, the second scenario would deem saving the child as permissible or even obligatory despite personal loss, and the third scenario would consider taking organs without consent as morally forbidden regardless of the potential to save lives.
