How to Appeal a Section Radar Speed Fine in Castellar: Free Downloadable Template (Word/PDF)

Receiving a speeding ticket from a section radar (radar de tramo) can be frustrating, especially when you believe you maintained a safe and legal average speed. A section radar does not measure your speed at a single point, but rather calculates your average speed over a set distance between two or more cameras. Fortunately, like any traffic fine in Spain issued by the DGT or local authorities, you have the legal right to appeal it if there are technical flaws, missing calibration certificates, or notification errors. This article provides a comprehensive guide on how to contest this specific type of fine in Castellar, along with a ready-to-use official legal template.

Instructions on how and where to submit it in Castellar

To ensure your appeal (recurso de alegaciones) is legally processed and considered by the traffic authorities, you must submit it within the statutory period—usually 20 calendar days from the day following the notification of the fine. If you submit it within this period, you maintain the right to the 50% early payment discount if the appeal is ultimately rejected, though submitting an appeal officially pauses the standard payment period.

In Castellar (Castellar del Vallès, Barcelona), you have several official channels to file your documentation:

• Online (Recommended): Through the Electronic Registry of the Spanish Directorate-General for Traffic (DGT) using a digital certificate, Cl@ve, or DNI electrónico. Alternatively, if the fine was issued by the local police (Policía Local de Castellar del Vallès), you can use the electronic office (Sede Electrónica) of the Ajuntament de Castellar del Vallès.
• In-Person: At any official government registry office (Registro General), or through the "Ventana Única". You can also request an appointment at the local traffic headquarters (Jefatura Provincial de Tráfico) in Barcelona.
• By postal mail via certified mail (Correo Administrativo) addressed to the competent traffic authority indicated on the notification letter.

ALEGACIONES

PRIMERA.- NULIDAD DE LA PRUEBA E INSUFICIENCIA DE GARANTÍAS TÉCNICAS. El presente expediente sancionador trae causa de una medición efectuada mediante un sistema de control de velocidad por tramo ("radar de tramo"). Se solicita expresamente la aportación al expediente del certificado de control metrológico y de verificación periódica en vigor del cinemómetro correspondiente, así como los fotogramas completos de entrada y salida del tramo que acrediten la correspondencia indubitada del vehículo sancionado, bajo apercibimiento de indefensión.

SEGUNDA.- MARGEN DE ERROR LEGAL. Conforme a la normativa de metrología legal aplicable y las órdenes ministeriales correspondientes, a la velocidad registrada por el radar de tramo debe aplicársele el margen de error máximo permitido (que varía según la velocidad sea inferior o superior a 100 km/h). Solicito que se recalcule la velocidad media imputada aplicando el citado margen de error reglamentario, lo que podría situar la velocidad dentro de los límites legalmente permitidos.

TERCERA.- INMUTABILIDAD DE LA CARGA DE LA PRUEBA. Corresponde a la Administración sancionadora la carga de probar los hechos constitutivos de la infracción y el perfecto estado de homologación y funcionamiento del aparato de medición en el momento exacto de los hechos.

Por todo lo expuesto,

SOLICITA A ESTE ÓRGANO:

Que tenga por presentado este escrito, lo admita a trámite, proceda a la anulación de la sanción impuesta y del expediente de referencia, o subsidiariamente, se acuerde la suspensión del procedimiento aportando los certificados técnicos solicitados.

En Castellar del Vallès, a [Insert Day] de [Insert Month] de [Insert Year].

Additional documentation required

To strengthen your appeal against a section radar fine in Castellar, you should attach supporting documents where applicable. While the burden of proof technically lies with the administration (to prove the equipment was calibrated), adding your own documentation can be decisive:

• A copy of the notification letter (multa) received by mail or accessed via the TESTRA / Dirección Electrónica Vial (DEV).
• A copy of your National Identity Document (DNI or NIE).
• If the vehicle was driven by someone else at the time, include the identification of the actual driver accompanied by their signed authorization.
• Any evidence supporting exceptional circumstances, if applicable (though technical challenges regarding calibration and margins of error are generally the most effective approach for section radars).

Expert Tip: When dealing with section radars (radares de tramo), the most successful legal arguments focus on demanding the complete maintenance, homologation, and metrological control logs of all cameras involved in the specific monitored stretch, not just one. Furthermore, ensure you carefully verify that the time stamps on the entry and exit photos match the precise distance of the measured section mathematically. If you are unsure about the procedure, consult a specialized traffic lawyer in Castellar before the 20-day deadline expires.
