I am an ex-pat British driver working for a small Spanish haulier, and have been parked up since Saturday supporting the strike. Whilst many in Europe may disagree with our actions they must understand that we simply cannot continue unless something changes dramatically. Fuel costs have increased by more than 20% this year, but the rates paid have not increased. The company I work for runs just three trucks internationally and to fill them up now costs just under 2000 euros - a year ago it cost about 1470 euros. We continually hear from the Government in Madrid and the EU in Brussels that they are trying to resolve the problem. The problem is we are running out of time whilst they sit on their fat behinds on six figure salaries telling us what we can and cannot do.

Today Gibraltar is utter chaos with Spanish and local drivers queuing at the fuel stations in Gibraltar panic-buying. Each petrol station is controlled by police to keep the traffic moving. Morrisons, the main supermarket here, received a delivery from the UK - their lorry had all its windows smashed by pickets on its way through Spain. Fresh food is now running out.

Here people are rushing to fill their tanks. Whether that is what is causing the local petrol stations to run out of petrol, or lack of deliveries, is another question. Clearly some arrangement enabling hauliers to pass on the increases in fuel prices to their contractors and therefore eventually to the consumer, is necessary. Why this isn't already the case is bewildering.

We were travelling down from Nice last night and were very tired after our business trip. We were jumped upon by many of the protesters on the boarder and felt very intimidated by the way they jumped out in front of our van. We told them we had nothing in the van and needed to get back to our home where my children, 24 and 13, were waiting for our arrival. They told us we would be sleeping there and would not allow us through. We had nothing in the van so eventually they allowed us to pass. I agree that protests are needed to but scaring people at 0230 is not the way to go about this and should allow people to make up their own minds to join in any protests.

I am a grower and exporter of organic fresh vegetables from Spain into the rest of Europe. Guaranteed, our season ends in July, but I still have crops in the ground that need to be harvested and exported to my supermarket customers. I am currently looking at sea freight alternatives so as not to let my UK customers down.

I live in Madrid, I have nothing to do with the strike, but in my work there is a lot of concern that the fuel is going to run out by the weekend, so all of them are filling their car's tank, and also they are talking about buying a lot of food before the stores run out of food. People are really concerned - some of them are not using the car, just for precaution and taking the bus. In work, all deliveries are being affected, nothing is normal, this is really affecting all of us, we want solutions fast!

Being a new resident of the EU, by way of the US, I find the cost of fuel to be high here in Spain but appreciate the value Europeans place on this precious commodity. The high price discourages wasteful usage, such as SUVs in abundance. I believe the EU governments are reaping a windfall in taxes (VAT) at the expense of normal working people that must purchase fuel. It seems in order to cap the VAT for the time being and raise it slowly government revenues begin to flatten or fall. Here in Barcelona, today, I don't feel the impact of the strike, yet, but it's coming.

Longer queues are starting to form at petrol stations here, as people fill up just in case. I also went to the supermarket early this morning as always but it was three times as busy as usual. If this carries on, petrol stations and supermarkets will be empty of fuel and fresh produce within a few days. Let's hope it doesn't last too long, everyone is affected by the massive hikes in fuel. This is the fault of governments which should have seen this coming years ago and prepared for it, together with the huge oil companies which probably "persuaded" them not to do anything.

What point is there in damaging Spain's economy in protest at a global phenomenon? Do the oil producing nations really care that a strike has taken place somewhere in Europe? It seems ignorant on the trade union's part.

I am totally pro-hauliers! In Italy we have been played around with in a very similar way with petrol rising some 15% whilst diesel within the same period of around 6 months rose by over 30%! No global price of petrol rise can justify this pricing behaviour and someone is simply making a hefty profit with nobody controlling. Bravo to the Spanish and usual shame on the Italians who don't even manage to organise a strike when it is really needed.

When you go on strike you do so to inconvenience those people who have the power to redress your grievance. In the case of the Spanish lorry drivers, British lorry drivers, French fishermen etc. the people who can lower oil prices ie Opec are not inconvenienced. The public and the government who are inconvenienced are completely impotent. It's like going on strike to complain about the weather - pointless. We all need to wake up to our over-dependence on cheap fossil fuels, then we will be less vulnerable to the decisions of Opec, which are outside the control of our governments.

I say, "Bravo" to the truckers in Spain and Portugal. The truckers here in the U.S. had some protests around the country a few months ago but we haven't seen any wide scale strikes. I believe that once the contracts they have with their customers expire and they are forced to raise their shipping prices, the general public will start massive protests as the cost of basic food items will more than double. It's going to get much worse before it gets better.

Well people think they have it hard in Europe, what do you think of the people working in poorer countries, like myself? The poor countries are suffering a lot more than the European richer counterparts, but I believe we are all suffering. It's about time we pulled the plug on Opec and all the other nasty oil companies, and take a leaf out of the Venezuelan president, but this time all of Europe stick together, so we can't be pushed. After all, we do produce our own oil, so we can be independent of the Arab states' oil.
I have just spoken to my son who works for a Suffolk-based removal company and he and his work colleague are on a removal job for the company and they are stuck in a car park 100 miles from Malaga. They have been prevented from continuing with their work schedule. This morning they were "directed" by the Spanish truck protesters into this car park. As I spoke to him, he told me there were about 20 other lorries, there to. The Spanish police were ensuring nothing bad happened and just keeping civil law.
