Driving Licence new and renewal

[grange]

We have been advised that if you do not speak Spanish you need to take an interpreter to Traffico at Alicante. As well as completed forms, residence certificate and medical certificate( whatever age you are). If you are not fluent it is easier to get a Gestoria to do this for you. Can anyone advise me if this is correct. When I went previously 5 years ago I did this myself and had no problem

A friend of ours continues to drive on a UK licence but has also been advised to get a medical because without this the insurance is void!
