You return from holiday or open a pile of accumulated post, and a bad surprise awaits you: an increased fixed fine. The initial amount has sometimes tripled, and the Trésor public (French Treasury) is already threatening to seize funds from your bank account. Faced with this stressful situation, many believe it is too late to act and that they must pay immediately to avoid trouble. However, French law provides specific mechanisms to contest an increased fine, even after the initial deadlines have passed. This comprehensive guide explains, step-by-step, how to assert your rights and have this increase cancelled or reduced.

To contest effectively, you must first understand how the fixed fine system works. In France, the processing of road traffic offences and certain minor offences of the first four classes is automated.
When an offence is recorded (by an automatic speed camera or a law enforcement officer), the ANTAI (National Agency for the Automated Processing of Offences) sends a violation notice to the home address of the registration certificate holder.
Fine amounts vary according to the class of the offence (most commonly 3rd or 4th class for road traffic violations):
| Type of Offence | Reduced Fine | Standard Fine | Increased Fine |
| :--- | :---: | :---: | :---: |
| 3rd class (e.g., speeding < 20 km/h outside built-up areas) | 45 € | 68 € | 180 € |
| 4th class (e.g., running a red light, using a phone while driving) | 90 € | 135 € | 375 € |

Contrary to popular belief, the issuance of an enforceable title for an increased fine does not close the door to contesting it. The Code de procédure pénale (French Code of Criminal Procedure) strictly regulates this possibility.
This is the fundamental text on the matter. Article 530 of the Code de procédure pénale states that the offender can lodge an objection against the enforceable title of an increased fine with the Ministère public (Public Prosecutor's Office) within 30 days from the date the increased fixed fine notice was sent.
If you did not receive the initial notice because you moved without updating your carte grise (vehicle registration document) within the regulatory one-month deadline, the law is strict but offers a way out.
According to Article 530-3 of the Code de procédure pénale, if you prove that you registered your change of address with the SIV (Vehicle Registration System) within 30 days following the sending of the increased fine, you will only be liable for the amount of the standard fixed fine (and not the increased one) when you pay.

For your contestation to be accepted by the Officier du Ministère Public (OMP - Public Prosecution Officer), it must be based on solid legal or factual arguments. Here are the most frequently accepted grounds:
This is the most classic case. You never received the letter containing the initial fine (lost by the post office, mail theft, incomplete address on the registration document). The administration must prove that you actually received the first notice, which is difficult without registered mail.
If your vehicle was stolen, destroyed, or if you had sold it before the date of the offence, you cannot be held responsible. You simply need to provide the police report for theft or the transfer certificate (certificat de cession) registered in the SIV system.
If a third party is driving with cloned plates using your registration number, you must file a police complaint immediately. This complaint is grounds for a total and automatic exemption.
If you had lent or rented your vehicle to a third party at the time of the facts, you can contest the fine by designating the actual driver, or by providing proof that you could not have been behind the wheel that day (plane ticket, employer certificate, etc.).

To better understand the practical application of these rules, here are two common situations explained.
Antoine owns a car. He moves from Lyon to Marseille on 1 June. Busy with his relocation, he forgets to update the address on his carte grise. On 15 June, his car is flashed for speeding at 15 km/h in a built-up area (a 4th-class offence).
Sofia goes to work abroad for 3 months, from January to March. During her absence, a violation notice for highly disruptive parking (a 4th-class fine of 135 €) is delivered to her letterbox in February. Upon her return in April, she discovers an increased fine notice of 375 €.

The contestation procedure must follow strict formalities, otherwise it will be automatically rejected.
Before starting, prepare the following documents in digital format (PDF or JPG) or paper:
1. The increased fixed fine notice received.
2. A copy of your carte grise (registration certificate).
3. A copy of your ID.
4. Specific proof supporting your grounds (transfer certificate, police report for theft/cloned plates, recent proof of address, employer certificate, travel tickets, etc.).
#### Option A: Online Contestation (Recommended - Faster and Free)
1. Go to the official ANTAI website: www.antai.gouv.fr.
2. Click on the "Designate or contest" tab.
3. Enter the increased violation notice number (consisting of 12 digits or 16 digits depending on the format), your last name, and the vehicle registration number.
4. Select the reason for your contestation from the options provided.
5. Write your argument clearly and concisely.
6. Upload your supporting documents.
7. Submit and carefully keep the acknowledgement of receipt of your contestation.
#### Option B: Contestation by Post (Traditional)
1. Fill out the exemption request form (formulaire de requête en exonération - the blue/green document attached to your increase notice).
2. Write a cover letter on plain paper, addressed to the Officier du Ministère Public (the exact address is on your increase notice).
3. Send the complete file *imperatively by registered mail with acknowledgement of receipt (lettre recommandée avec accusé de réception - LRAR)*. Keep a copy of all sent documents, the mailing slip, and the signed acknowledgement of receipt.
For certain offences (notably speeding, failure to respect safety distances, running red lights), the law requires you to pay a deposit (consignation) beforehand for the contestation to be admissible. The amount of the deposit is equal to the amount of the fine.

A simple procedural error can lead to the rejection of your request without the merits of your case even being examined.

Yes. If you successfully contest the increased fine and the case is dismissed or you are acquitted by the court, the associated point deduction is cancelled. If the points had already been deducted, the Ministry of the Interior must restore them.
If you do not pay and do not contest the increased fine, the Trésor public can issue an Opposition au Transfert du Certificat d'Immatriculation (OTCI - Opposition to the Transfer of the Registration Certificate). This legally prevents you from selling or gifting your vehicle. To lift this opposition, you must either pay the debt or obtain a dismissal decision from the OMP following an admissible contestation.
Yes. The OMP has three options: they can declare your contestation inadmissible (if deadlines or forms are not respected), dismiss the case (you are exonerated), or decide to prosecute you before the Tribunal de police (Police Court). Before the judge, you will be able to present your defence arguments in person.
If you acknowledge the offence but are experiencing severe financial difficulties (job loss, over-indebtedness), you can write to the Trésor public accountant (whose address is on the notice) to request a payment extension, an installment plan, or a grace reduction (remise gracieuse) of the increase. You must imperatively attach all proof of your income and expenses (tax notice, proof of registration with France Travail [formerly Pôle Emploi], etc.).
