Current on-highway diesel prices in the United States, updated weekly from the U.S. Energy Information Administration. Used by carriers, fleet managers, and owner-operators to set fuel surcharges and project operating costs.
As of the week ending 2026-04-13, the U.S. on-highway diesel average is $5.608/gal, down $0.035 from last week. For a typical carrier operating 125,000 miles annually at 6.5 MPG, a $0.10/gallon increase translates to roughly $5,500–$6,000 in additional fuel cost. Most shipper–carrier contracts include fuel surcharge clauses that adjust weekly with the EIA's published price; tracking this index is critical for margin management across for-hire fleets, private fleets, and owner-operators.
The EIA reports diesel prices for five Petroleum Administration for Defense Districts.

| PADD 2 (Midwest) | $5.382 | +$0.078 |
| PADD 3 (Gulf Coast) | $5.310 | −$0.105 |

| PADD 5 (West Coast) | $6.822 | −$0.102 |

The U.S. Energy Information Administration (EIA) publishes weekly on-highway diesel prices every Monday for the prior week. TruckRadar.AI updates this data weekly from the EIA's public API.
Diesel fuel typically represents 25–35% of a trucking company's total operating costs. A $0.10/gallon change in diesel price translates to roughly $5,500–$6,000 per year in fuel cost for a truck averaging 125,000 miles annually at 6.5 MPG. Most carrier contracts include fuel surcharge provisions that adjust with weekly EIA diesel prices.
California consistently has the highest diesel prices in the country due to state fuel taxes, environmental regulations, and refinery capacity constraints. West Coast states (CA, OR, WA) and New England states (CT, MA, NY) typically rank highest. Midwest and Gulf Coast states typically have the lowest prices due to proximity to refineries.
PADD stands for Petroleum Administration for Defense District. The EIA divides the U.S. into 5 PADD regions for fuel price reporting: PADD 1 (East Coast), PADD 2 (Midwest), PADD 3 (Gulf Coast), PADD 4 (Rocky Mountain), and PADD 5 (West Coast). Diesel prices vary significantly across PADD regions.
For a fleet vehicle traveling 125,000 miles annually at 6.5 MPG, you'll consume ~19,230 gallons. A $0.10 increase costs $1,923; a $0.50 increase costs $9,615. Multiply by your fleet size to project the total impact. Carriers reference the EIA weekly price in fuel surcharge formulas.
