Volvo Trucks will lay off around 300 more employees later this year due to weaker truck demand in 2016, according to a report in The Roanoke Times.

The layoffs are expected to take place in September and will affect workers at its New River Valley truck plant in Dublin, Va. This will be the second round of major layoffs at the facility for the truck manufacturer, which in February laid off as many as 700 employees.

The New River Valley plant is one of Volvo Group’s largest manufacturing facilities, assembling the Volvo VNM, VNL, VNX, VHD and VAH trucks.

The layoffs are part of a plan the company put in place late last year when it projected demand to fall off after a stellar 2015. Class 8 truck demand in particular has been reported at low levels throughout 2016 as a weaker economy and lower freight demand  have made carriers cautious about ordering new vehicles.

Daimler Trucks North America has also responded to truck order reductions with major layoffs, letting go 1,240 workers across its North American production wing as a result.
