Principle 3: Clearly Guide Roadway Users

Motorists must understand what is expected of them as they approach and pass through the construction area. Flaggers, signs, pavement painting, barriers, or other types of TTC devices can all communicate instructions to drivers. Regardless of the methods used, the communication should be clear, effective, and easily understood. For example, a flagger should provide positive directional guidance to all road users passing through the roadwork zone.

It is important that the communication instructs all types of roadway users, including motorists, motorcyclists, bicyclists, and pedestrians. It is also necessary to consider whether those with disabilities will be able to receive and understand the communication.

It is also important to clearly indicate the intended path of travel for each type of roadway user. Devices that highlight or emphasize the planned-for path for vehicles, bicyclists, and pedestrians should be easily seen and understood.

It is important to remove any TTC device that is no longer required. For example, a sign that announces a lane closure that is applicable during a nighttime-only resurfacing project should be removed or completely covered during the daytime. This is part of clear communication.
