Mounties in Alberta say they害羞草研究所檙e keeping traffic moving on the Trans-Canada Highway despite a roadside carbon-levy protest, and say five large farm tractors have already caused a multi-vehicle crash.

Protesters slowed traffic on the Trans-Canada just west of Calgary on Monday to protest the scheduled hike in the federal carbon levy, which boosted gas prices at the pumps by about three cents a litre.

That protest has continued but police say traffic is moving as demonstrators are being kept off to the side of the road.

Police say another carbon-levy protest further south in the Crowsnest Pass on Monday led to a multi-vehicle crash after five large farm tractors refused to stop for police.

The investigation into that pileup continues.

In Calgary Tuesday, Premier Danielle Smith urged all protesters to keep the demonstrations legal.

The province has in place the Critical Infrastructure Defence Act, which provides added penalties for those who tie up key infrastructure and transportation corridors.

Smith said she will leave it up to police to decide when and if to use the defence act.

Police, in a news release, said safety is paramount.
