Step-by-step explanation:
In the context of toll booth stations, a steady red light signifies that the vehicle must come to a complete stop. It serves as a signal to indicate that the driver should wait for permission to proceed, usually after paying the toll fee.
For example, when a vehicle reaches a toll booth, the steady red light indicates that the driver should stop and wait for the toll booth attendant to collect the necessary payment before allowing the vehicle to continue.
