What type of receipts may support daily logs?

Fuel receipts are crucial in supporting daily logs as they provide verifiable evidence of a vehicle's fuel consumption and, consequently, the distance traveled. When operators maintain daily logs for regulatory purposes, they must document hours of service, vehicle usage, and routes taken. Fuel receipts serve as a reliable reference point that correlates with the mileage recorded in these logs. This is important since regulatory authorities often require proof of compliance with hours-of-service regulations, and fuel transactions can help substantiate the information reported in the daily logs.

In contrast, while insurance receipts, tax receipts, and training certificates may have relevance in broader operational contexts or during audits, they do not directly correlate with the daily operational metrics that fuel receipts provide. Thus, they are less effective in supporting the specific details captured in daily logs related to fuel usage and mileage.
