Final answer:
A sign indicating that a lane is reversible and instructs to see lane control signals means that the lane can change direction based on signals to manage traffic flow.
Step-by-step explanation:
When we see a sign indicating that a lane is reversible, "see lane control signals," it informs us that b) the lane can change direction based on signals. This means that the direction of traffic in that particular lane can be changed, usually to accommodate varying traffic flow during different times of the day. For instance, a lane might be used for inbound traffic during the morning rush hour and then switched for outbound traffic in the evening rush hour, all controlled by traffic signals. Therefore, understanding how to interpret and respond to lane control signals is crucial for both road safety and traffic efficiency.
