District of Columbia → North Carolina · Interstate 95 / Interstate 66
Before turning the key for Raleigh, North Carolina, on the homeward run from Washington, District of Columbia, do a quick inventory sweep of onboard equipment: proposal binder, undelivered promotional items, and visitor badge should each go into a separate compartment so nothing slides into the footwell during a sharp brake. Interstate 95 / Interstate 66 accepts the 443 km (275 miles) of the return in roughly 4h 13m. Pulling out of Washington (the capital of the United States and seat of the federal government), the road eventually puts the driver back in front of the urban skyline of Raleigh (the capital of North Carolina and anchor of the Research Triangle). Refueling sits near $37.08 for the same 40.3 liters (10.6 gallons) at the EIA national average benchmark. Return reimbursement, calculated against $0.43/km, returns $190.49 into the driver's wallet. Snap the closing odometer with the phone camera and attach it directly to the Clara receipt — internal controls accept photographic evidence without a supplementary spreadsheet.
