Final answer:
Tollbooth stations do not use actual wires that touch cars; they use induction loops in the pavement to detect cars for traffic management and tolling.
Step-by-step explanation:
The statement about a bridge tap needing to be addressed before completing a job seems to be related to telecommunications, not roadway systems. However, addressing the question in the context provided, tollbooth stations may have sensors or induction loops embedded in the pavement, not wires that physically touch the vehicle. These sensors can detect the presence of a car as it approaches to help manage traffic flow, record tolling information, or signal systems to initiate various responses, such as displaying the toll amount or signaling a gate to lift. This is done using a principle of physics where a large metal object, such as a vehicle, disturbs the magnetic field of the induction loop, allowing the system to detect the car's presence.
