Federal taxes on diesel fuel, truck tires, heavy equipment and heavy-vehicle road use are set to expire Sept. 30 unless Congress acts on a transportation bill before hand.
The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) expired in 2009, but taxes going into the Highway Trust Fund were collected for an additional two years. That extension is about to run out.
Congress will debate to extend the multi-year transportation authorization bill when it reconvenes after its summer recess.
