In British Columbia, the Ministry of Transportation and Infrastructure’s (TranBC) Commercial Vehicle Safety and Enforcement (CVSE) branch has issued a Circular about an approved additional weight tolerance to compensate for the heavier fuel tanks used by LNG fueled trucks and buses. Because the fuel tanks for LNG and CNG vehicles are heavier than the tanks for gasoline or diesel engines on large trucks that already are at or near the maximum legal weight, this can impose a penalty on how much cargo can be hauled. CVSE is allowing LNG-powered trucks to be 1,500 kilos (about 3,300 lbs.) heavier than traditional diesel and gasoline trucks. This weight allowance means LNG-powered trucks can carry the same maximum amount of freight as diesel-powered trucks. CVSE is also preparing a Vehicle Inspection Manual to assist inspectors in examining the “nuts and bolts” of LNG-powered vehicles during roadside inspections and regular safety checks. In the U.S., there are existing variances to the gross vehicle weight limits for auxiliary power units and idle reduction technologies on trucks. NGVAmerica has been working with the American Trucking Associations and supporters in Congress on a similar NGV exception for the U.S.
