Final answer:
When a stationary emergency vehicle displays red and blue lights, one should reduce speed, move over to give space if possible, or slow down, prepared to stop if moving over is not feasible.
Step-by-step explanation:
When encountering a stationary emergency vehicle displaying lighted red and blue lights, the proper action is as follows:
- Reduce speed.
- Move over to another lane if safely possible to give space to the emergency vehicle.
- If moving over isn't possible due to road conditions or traffic, slow down significantly and be prepared to stop if necessary.
This protocol ensures both the safety of the individuals in the emergency vehicle and those in nearby vehicles. It is similar to how one would stop at a red traffic light under normal circumstances, understanding that exceptions may exist in extreme situations such as a medical emergency while en route to a hospital. However, in regular conditions, complying with traffic laws and giving right of way to emergency vehicles is the legally and morally correct action.
