Remember that Spain has much stricter drink driving laws than the UK and only allow 0.25 milligrams of alcohol per millilitre of blood - the UK limit is 0.8. It's even less for new drivers with a very low 0.1 mg/l limit.
If you're caught driving with over 0.05 per cent, you could face anything from a severe fine, withdrawal of your licence, up to imprisonment.
On the spot fines are issued, so you don't have any 'days of grace'. And don't forget to ensure an you get an official receipt from the officer collecting the fine.
You'll also need to be wearing front and rear seat belts at all times.
Also speed limits are implemented rigorously with frequent Radar traps.

It is compulsory to carry a replacement bulb set in the vehicle, as is a reflective triangle.
Hi-viz (Day-glo) vests are now compulsory in Austria, Italy and Spain (and likely to become compulsory throughout the EU) if you need to walk on a motorway. Apparently, all occupants of the vehicle need to have one, so make sure you carry enough in the vehicle.
