The City of Pembroke is reminding drivers of the rules of the road when it comes to flashing traffic signals.The key message is that drivers should not be stopping for the flashing amber light. A release was issued by the city Monday because of instances with the traffic signals at the intersection of Pembroke Street East and Howard Street going into default mode, which means the lights on Pembroke Street East are flashing amber and the lights on Howard Street are flashing red.According to the release, the city is working with Ottawa River Power Corporation/Ottawa River Energy Solutions to rectify the situation and some repairs have already been made. A shutdown of the signals has been tentatively set for Aug. 6 for additional repair work. The Ontario Provincial Police is scheduled to provide traffic control during maintenance.Should the traffic signals go into default mode prior to repairs, the Highway Traffic Act directs that drivers approaching a flashing amber light may proceed with caution while drivers approaching a flashing red light should stop, yield the right of way to traffic then proceed when safe to do so. Intersections with flashing red in all directions should be treated as a four-way stop, as should intersections with no lights during a power outage.
