Final answer:
True, you should never drive in a lane marked with a red X, as it signifies the lane is off-limits and it is to ensure road safety. A red X helps control traffic and is legally binding, with some extreme exceptions like emergencies.
Step-by-step explanation:
True: You should never drive in a lane with a lane-use signal displaying a red X. A red X over a traffic lane means that driving in that lane is prohibited. This rule is put in place to control traffic flow and enhance safety on roadways. It's important to obey these signals just as you would a standard red traffic light. Traffic lanes with a red X are often used for managing congestion, during emergencies, or when an accident has occurred in a lane.
In scenarios where speed is mentioned, like vehicles speeding through an intersection, the presence of a traffic signal generally forces drivers to slow down. Hence, although the query also touches on speeding and the general need to respect traffic signals, the key issue at hand concerns lane-use signals and their mandatory nature.
However, there are extreme exceptions, such as the given hypothetical scenario of driving a pregnant woman to the hospital. In most jurisdictions, the law maintains that you must stop at red lights, but a Utilitarian approach might suggest an ethical exception. It should be noted, though, that such decisions could have legal consequences and are not the norm.
