To appeal against the fine charged to you, please respond to the fine email with your evidences attached. Evidences can be in any form/type that is sufficient for your appeal (e.g. photos, videos, fuel receipts, timestamps).
The relevant team will have it reviewed. All appeals are subjected to approval. Should we find your evidence sufficient, your appeal will then be successful.
Tip: Best practice is to always keep your fuel receipts by taking a full photo of it (before disposing it).
