Oklahoma → Texas · Interstate 35 / Interstate 40
The night-time return from Oklahoma City, Oklahoma, to Dallas, Texas, deserves its own protocol: anti-glare driving glasses on, dashboard light dimmed to the lowest setting, and well-lit truck stops pre-identified as candidate rest stops. The 362 km (225 miles) of Interstate 35 / Interstate 40 and the 3h 27m of driving cross zones with patchy cellular coverage during the small hours. Approximate refuel cost on the way back stays at $30.27 for the 32.9 liters (8.7 gallons) consumed. Forecast reimbursement for the night leg holds at $155.66 applying the prevailing $0.43/km — without an automatic night premium in the IRS standard mileage rate (2025) table. If the company pays night-driving overtime, open a separate line on the Clara receipt: the payroll integration already recognizes the entry.
