A new weigh-in-motion system, designed to weigh lorries at highway speeds, has been installed on Route 2 in the Canadian province of New Brunswick.

The system features loops and plates embedded in the roadway to track the movement of each truck and records weight, axle configuration, and other information automatically.

Its aim is to reduce fuel consumed by trucks by allowing the majority of them to pass by the scale without slowing down, and is expected to save 4,000t of greenhouse gas emissions each year.

The CA$500,000 ($486,000) system has been funded by the New Brunswick Climate Action Fund.

The province has already deployed the system at Longs Creek, Deerwood, Waweig and Salisbury west.
