What AB 1421 does
An act to add Section 3092.7 to the Vehicle Code, relating to vehicles.
Existing law requires the Chair of the California Transportation Commission to create a Road Usage Charge Technical Advisory Committee in consultation with the Secretary of Transportation to guide the development and evaluation of a pilot program assessing the potential for mileage-based revenue collection as an alternative to the gas tax system. Existing law additionally requires the Transportation Agency, in consultation with the commission, to implement the pilot program, as specified. Existing law repeals these provisions on January 1, 2027.
This bill would require the commission, in consultation with the Transportation Agency, to consolidate and prepare research and recommendations related to a road user charge or a mileage-based fee system. The bill would require the commission to submit a report, as specified, on the research and recommendations described above to the appropriate policy and fiscal committees of the Legislature by no later than January 1, 2027. The bill would require the commission to consult with appropriate state agencies and other stakeholders, as specified, in preparing the research and recommendations and report described above.

What happens next
It is in the Senate, its second house. The last recorded action was on January 29, 2026.
The Governor can sign the bill, veto it, or let it become law without a signature. Until the decision, sign and veto request letters are the remaining channel, and the Department of Finance's enrolled bill report carries weight on anything with a fiscal effect. If signed, most provisions take effect January 1, and implementation moves to the agencies named in the bill.
What it means for transportation organizations
This is the stage where language still changes. Amendments taken in committee are the ones that reach the Governor, so an organization with a stake in the drafting has a reason to be in that conversation now rather than after the vote.
The transportation group at Capitol Axis handles that for transportation clients.
