California → Arizona · Interstate 5 (San Diego Freeway)
Returning from San Diego, California, back to Phoenix, Arizona, the itinerary retraces the same 567 km (352 miles) of the outbound segment, predominantly via Interstate 5 (San Diego Freeway), adding another 5h 24m to the corporate odometer. Unlike the outbound leg, the homeward journey is usually executed at the close of the business day, when heavy truck traffic, accumulated fatigue, and dropping daylight all demand sharper focus. Anyone hoping to ease the arrival back into Phoenix, the fifth-largest US city and capital of Arizona, may consider an overnight stop in a midpoint town and splitting the haul into two shorter stints. Fuel expense holds steady near $47.38, totalling roughly 103.0 liters for the entire trip when added to the outbound segment. The return reimbursement reaches $243.81, doubling the aggregate payout for the full journey. Log each leg separately in the Clara receipt, with distinct timestamps, so the paperwork accurately mirrors the vehicle's actual movement.
