Missouri → Kentucky · Interstate 70 / Interstate 64
The night-time return from St. Louis, Missouri, to Louisville, Kentucky, 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 459 km (285 miles) of Interstate 70 / Interstate 64 and the 4h 22m of driving cross zones with patchy cellular coverage during the small hours. Approximate refuel cost on the way back stays at $38.36 for the 41.7 liters (11.0 gallons) consumed. Forecast reimbursement for the night leg holds at $197.37 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.
