Truck dealers in Massachusetts are complaining that a new requirement mandating that 7% of all new medium and heavy-duty truck sales are electric vehicles is hurting their business, according to CBS News.

The dealers say the demand for EVs that would justify the mandate from Governor Maura Healey's administration isn't there yet, and that the range and charging infrastructure are not adequate to serve the needs of the trucking industry.

One dealer, Peterbilt Stores New England in Plainville, Massachusetts, is not even stocking 2025 models of heavy-duty trucks.

But the Environmental Defense Fund says regulations such as this mandate are essential to protect the quality of air in the state, adding that, over the past year, about 35,000 zero emission trucks have been sold in the U.S.
