In Spain you drive to the right and overtake on the left. Always respect the safety distance.
Always give priority to pedestrians who cross or are about to cross a road; even if there are no pedestrian crossings on the ground.

The infrastructures are extremely efficient. In general, autovias and autopistas are the best and most efficient routes to travel throughout the Iberian Peninsula.

DOCUMENTS TO DRIVE IN SPAIN

Driving license, registration certificate and valid insurance certificate. If you are driving a vehicle that is not your own, we recommend that you take a DELEGATION TO CONDUCT. This is a delegation of the vehicle owner with an authenticated signature.

VEHICLE EQUIPMENT

It is compulsory to have the reflective jacket and the spare tire in the car with its replacement kit. It is also mandatory to have 2 TRIANGOLI to use in case of breakdown or accident; the non-exposure, even of only one, may result in a sanction by the bodies in charge.
To those who wear eyeglasses, it is advisable to have a couple of reserves in the car.

A sign with a blue background and white character indicates a separate dual carriageway, that is, a car or an autopistas.
The roads managed by the state are identified by the letter A followed by a number; they are generally free. The roads numbered in progressive from 1 to 6, are those that start from 0 km of Sun Gate.
The separate dual carriageway roads, granted by the State, are generally paid and identified by the letters AP followed by a progressive number. To these are added the so-called “radial highways”, identified by the letter R; they connect all the Capital to the motorway sections.

There are also numerous motorways operated by the Spanish Autonomous Communities. Each one adopts a special classification, numbering and color of the signage. Refer to the individual areas for further practical information.
