Tennessee → Kentucky · Interstate 40 / Interstate 65
The night-time return from Nashville, Tennessee, 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 294 km (183 miles) of Interstate 40 / Interstate 65 and the 2h 48m of driving cross zones with patchy cellular coverage during the small hours. Approximate refuel cost on the way back stays at $24.56 for the 26.7 liters (7.1 gallons) consumed. Forecast reimbursement for the night leg holds at $126.42 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.
