How many orange and black TTC signs are required in each direction on a 2-way, 2-lane rural roadway?

In a 2-way, 2-lane rural roadway, the standard practice for Temporary Traffic Control (TTC) requires the placement of orange and black signs in a way that adequately informs drivers of the upcoming work zone and any changes to traffic patterns. According to the guidelines, each direction of traffic should have specific signage to ensure visibility and comprehension.

The answer of three signs in each direction aligns with the regulations that aim to provide clear communication to drivers. This includes two signs upstream of the work zone to provide adequate warning and one additional sign at the immediate vicinity of the work zone to reinforce the change.

This approach ensures that drivers have sufficient notice to adjust their speed and responding behavior before they enter the work zone. Proper signage placement is a critical component of traffic safety and effective traffic control in work zones.
