A Catalan truck driver on strike displays a sign reading, "I... transport strike. Minimum compulsory tariffs", after strikers blocked a street in Barcelona June 11, 2008, during a protest against rising fuel costs. Truckers picketed distribution centres and called for a minimum haulage tariff to counter a 35 percent rise in fuel costs over the past 12 months. REUTERS/Gustau Nacarino (SPAIN)
