Section 127(s) of Title 23 of the United States Code, as amended by the Consolidated Appropriations Act of 2019 (PL 116-6), increases the weight limit for natural gas vehicles operating on the interstate Highway System by an extra 2,000 lbs. This increases the limit from 80,000 lbs to 82,000 lbs.

Federal Highway Administration issued a departmental memorandum providing further guidance for this weight allowance.

FHWA Guidance includes the following:

1. State authorities must allow the additional weight on the Interstate Highway System.
2. State authorities must provide reasonable access to the Interstate.
3. Weight allowance applies beyond the Gross Vehicle Weight (extends to single axel, tandem axel and bridge weight formulas limits).
4. Weight allowance must be taken in addition to other weight allowances.
