In which document would you find the guidelines for TTC?

The guidelines for Temporary Traffic Control (TTC) are primarily found in the Manual on Uniform Traffic Control Devices (MUTCD). This document sets forth national standards for all traffic control devices, including those used in work zones. It provides the foundation for the proper placement, usage, and visibility of traffic control devices to ensure safety and efficiency for both road users and workers in the work zones.

The MUTCD is essential because it ensures uniformity in traffic control across different jurisdictions, thereby promoting a safer driving environment. The guidelines contained in the MUTCD cover various aspects of traffic control devices, including signs, signals, and pavement markings, emphasizing their correct implementation in TTC situations to guide drivers through work zones safely.
