It might be obvious, but in Spain you drive on the right (the opposite to the UK).
At all times motorists must have in the car:
2 red warning triangles – in the event of breakdown or accident, these must be placed in front of and behind the vehicle.
A spare pair of glasses – if the driver wears glasses
A spare wheel
A full set of spare light bulbs, and the tools to change them
A reflective jacket
A certificate of insurance – whether a hired car, or a if a UK registered car, your UK insurance certificate (generally only valid for a stay of less than 3 months)
Seat belts are required to be on at all times in the front and back seats
No child under the age of 12 should be in the front seat
Small children must be in an approved child safety seat in the back
Do no talk on mobile phones when driving. It is forbidden – even if pulled over at the side of the road
Using an earpiece is also prohibited, but is allowed to be used with a completely hands-free unit
You must be over 18 years old to drive in Spain
Remember that speeding fines are on the spot for non-residents. The speed limit on Spanish motorways has reverted to 120 kilometres per hour (kph) after being dropped to 110kph in February 2011 in an effort to educate drivers that higher speeds consumer more petrol.
