How often should a TTC zone be checked for safety and compliance?

The correct response indicates that a TTC zone should be checked routinely. This approach ensures consistent monitoring of the work zone environment, which is critical for maintaining safety for both workers and road users. Routine checks allow for the early identification of potential hazards, compliance with established traffic control plans, and adjustments to temporary traffic control devices as needed.

Routinizing the inspection process helps build a safer work zone by fostering a culture of diligence and safety awareness among workers and personnel. The frequency being labeled as 'routinely' suggests a systematic and regular approach rather than adhering to a predetermined daily, weekly, or conditional schedule, which might overlook necessary adjustments that could arise from ongoing traffic conditions or work zone changes.
