To confirm the existence of a specific vehicle selected from the fixed asset register, the best indirect evidence would be to compare the registered details of the vehicle with a date-stamped photograph. This method provides a verifiable form of evidence that the vehicle exists and matches the details recorded in the asset register. It ensures that the vehicle is still in possession of the organization and can be indirectly verified without the need for physical presence at an off-site location.
