DGT's CTDA

DGT: Spanish traffic authority.

CTDA: DGT's center for automated speeding fines.

The letter you get if you have been caught speeding in Spain is sent by CTDA (Centro Tratamiento Denuncias Automatizadas in Spanish). If you need to reach them, do not hesitate to dial their number, there is always an English speaking operator available.

50% reduction: check

Ok, so I got a new fine. I suppose I am not the best driver out there. 100 euro again, this time in Lanzarote. The car rental company sent me an e-mail and two weeks later I had the letter... I set an alarm one month later, and tried to complete the payment online. It would charge 100 euro. I called the number in the letter and in 30 seconds I got the 50% reduction again (more details here).

Apparently, Spanish Traffic Authority will rather re-open the early payment window than making a mistake. A friend got a fine last summer, and will be back in Mallorca in two weeks. He got the fine 9 or 10 months ago. Called this numer, told them they had used an old address and still got the 50% reduction. No reason to fear that he might get an on-the-spot fine back in Spain.
