Drivers approaching the Armdale Rotary in Halifax now have to yield the right of way to those already in the circle.

Nova Scotia transportation officials met Tuesday with municipal officials to clarify the rules for the busy intersection in the southwest part of the city.

"They confirmed it's not one-on-one behaviour any more, it's actually yield upon entry," Coun. Linda Mosher, whose area includes Armdale, told her colleagues Tuesday night.

So unless a traffic control device or police officer is directing traffic, drivers already in the circle have the right of way. This is the rule for European-style roundabouts.

The municipality and the Transportation Department had been arguing about the rules of the road since the provincial Motor Vehicle Act was changed last October.

Mosher claimed the Armdale Rotary had officially become a roundabout. But the province said it was still a rotary, which meant drivers take turns entering and exiting the intersection.

Mosher says municipal and provincial officials will meet to develop a communications plan to let drivers know about the rules.

"I'd probably avoid the rotary if you could for the next little while," she said with a laugh.

About 55,000 cars go through the Armdale Rotary every day.
