Vehicles can become a significant grant cost through fuel, maintenance, insurance and staff travel. A vehicle logbook helps an NGO show how transport resources were used, which projects benefited and whether unusual mileage or fuel patterns need review.
Record every official trip
The log should capture date, driver, purpose, destination, project, opening and closing odometer readings and authorization where required. The information should be recorded close to the time of travel rather than reconstructed at month-end.
Connect fuel use to mileage
Track fuel purchases alongside kilometers traveled. Large changes in fuel efficiency may indicate maintenance needs, recording errors or unauthorized use. The goal is not to expect identical consumption every month, but to identify patterns that deserve explanation.
Separate project and personal use
If organizational policy permits limited non-project or personal use, define how it is approved and paid for. Do not charge donor grants for mileage that did not support the funded project.
Link maintenance to the vehicle record
Service history, repairs, tire changes and insurance information should connect to the vehicle asset record. See grant equipment maintenance costs for life-cycle budgeting.
Useful logbook fields
- Date.
- Driver.
- Project or cost center.
- Trip purpose.
- Destination.
- Opening odometer.
- Closing odometer.
- Kilometers traveled.
- Fuel purchased.
- Authorizing person.
Example
A project vehicle records 3,000 kilometers in one month but the activity calendar shows only a small number of field visits. Finance and operations review the logbook, fuel receipts and odometer to understand whether the difference reflects additional approved travel, a recording error or unauthorized use.
Review monthly
Compare mileage, fuel cost and maintenance patterns periodically. Review incomplete logbooks promptly because missing details become harder to reconstruct later. A supervisor should sign off after checking reasonableness.
Use the data for future budgeting
Historical mileage and servicing costs provide useful evidence for new proposal budgets. They can help estimate fuel, driver time and maintenance more realistically than generic assumptions.
What to do next
Use the Grant Budget Sanity Checker to test whether transport assumptions are realistic and explainable.

Control fuel cards and vouchers
If the organization uses fuel cards, vouchers or supplier accounts, reconcile them to vehicle logs and authorized trips. Unused vouchers, duplicated fuel claims or purchases inconsistent with vehicle capacity should be investigated promptly.
Include driver responsibilities
Drivers should understand who can authorize trips, how incidents are reported and what records must be completed. Where several projects share a vehicle, accurate project coding is especially important so transport costs are allocated fairly.
At closeout, confirm how donor-funded vehicles will be transferred, retained or disposed of according to the award terms, and keep the final odometer and condition record with the asset file.
Review accidents, fines and unusual incidents separately
Vehicle incidents should not be buried inside routine logbook entries. Keep a separate record of accidents, traffic fines, damage, insurance claims and disciplinary follow-up where relevant. This helps the organization distinguish normal operating costs from avoidable or exceptional events.
Where donor-funded vehicles are shared across projects, review mileage allocation periodically to confirm one grant is not carrying a disproportionate share of fuel and maintenance without a reasonable basis.
Use monthly logbook reviews to compare planned project travel with actual vehicle use and investigate material differences while records are still recent.
Use monthly logbook reviews to compare planned project travel with actual vehicle use and investigate material differences while records are still recent.
Retain completed logbooks with fuel and maintenance records so transport costs can be traced during donor review or audit.
Include vehicle-use controls in driver onboarding so staff understand project coding, authorization and documentation requirements before using grant-funded transport.
Frequently asked questions
What should an NGO verify first when reviewing vehicle logbook controls?
Start with the authoritative records, donor requirements, responsible owner, and the specific risk the control is intended to reduce.
Who should own the control?
Assign one accountable owner, then involve finance, program, MEL, operations, compliance, or leadership where their approval or evidence is required.
How often should it be checked?
Review it on the operating cycle that matches the risk and whenever a material change in staffing, assets, data, location, or donor rules occurs.
What is a common failure point?
Weak documentation, outdated records, inconsistent practices across locations, and controls that exist on paper but are not followed are common problems.
How should leadership respond to a serious exception?
Document the issue, assess the operational and donor impact, assign corrective action, and escalate quickly when the exception creates material compliance, financial, or safeguarding risk.
Conclusion
Grant Vehicle Logbook Controls should help your organization make grant operations more reliable and auditable. Keep the control evidence current, make ownership clear, and act on material exceptions before they become donor or delivery problems.
