Final answer:
On a highway, you may cross a single broken white line to pass and change lanes, provided it is safe. The presence of a broken white line indicates lane changing is allowed, highlighting the importance of observing all traffic rules and the existing speed limit for roadway safety.
Step-by-step explanation:
If you are driving on a highway next to a single broken white line marking, the correct action you can take is: You may cross the line to pass and change lanes. In most traffic systems, a broken white line indicates that you are permitted to change lanes when it is safe to do so. However, always ensure you are observing the rules of the road, as well as the speed limit and traffic around you before changing lanes or passing another vehicle. It's important to drive responsibly and maintain control of your vehicle to ensure the safety of all road users.
As an additional point of reference, in a case where there is an urgent situation, such as a pregnant woman in the backseat about to deliver, Rule Utilitarianism (RU) might suggest that breaking a traffic law, such as going through a red light at 4 AM when no other cars are around, could be morally acceptable if doing so results in greater utility by getting the person to the hospital more quickly.
