Which of the following is not typically a responsibility of a TTC technician?

A TTC technician's primary responsibilities encompass various aspects of traffic management and safety in work zones. Among these duties, conducting vehicle inspections is typically outside the scope of a TTC technician's role. This position focuses more on traffic control measures and ensuring effective implementation of traffic management strategies rather than inspecting the integrity or safety of vehicles.

In contrast, the design of traffic control plans is fundamental to a TTC technician's work, as it involves devising the layout and signage necessary to direct traffic safely through or around work zones. Implementing signage for work zones is also a crucial responsibility, as it ensures that drivers are adequately informed of potential hazards and alternative routes.

Furthermore, providing training on traffic control is an important aspect of the role, as it helps ensure that all personnel involved in work zones understand safety protocols and proper traffic management techniques. Thus, conducting vehicle inspections does not align with the typical duties of a TTC technician, highlighting why this choice is correct.
