Final answer:
One should slow down and be prepared to stop, keeping a safe distance from the vehicle making a left turn at a 4-way intersection, ensuring safety and adhering to traffic laws.
Step-by-step explanation:
When you are approaching a 4-way intersection and you see a car facing you with their left turn signal on, the safest action to take is not specifically mentioned in the options provided. However, the general recommended action in such a situation would be to slow down and be prepared to stop if necessary, keeping a safe distance from the turning vehicle. This would ensure safety for all parties involved. In some cases, the correct response can be to yield to the oncoming vehicle making the left turn, especially if you are also turning left or if the opposing vehicle has begun the turn and you need to avoid a collision. Always prioritize safety and be aware of the traffic laws and right-of-way rules that apply to the specific intersection you are facing.
When approaching a 4-way intersection and encountering a car facing you from the opposite direction with their left turn signal on, you should slow down and move away from the approaching vehicle. This is because the car is signaling its intention to turn left, and there is a risk of collision if you continue at the same speed and position.
