Slovenia has become the first EU member state to implement fuel rationing to tackle disruptions caused by the US-Israeli strikes on Iran and its retaliation on their allies in the Gulf - most major players in world energy markets.
Many countries have been experiencing steep hikes in fuel prices.
In Slovenia, this has resulted in so-called "fuel tourism", as drivers from neighbouring countries, particularly Austria, take advantage of the lower, regulated prices here.
Under the new measures, private motorists in Slovenia will be restricted to a maximum purchase of 50 litres of fuel per day. Businesses and farmers have a more generous allowance of 200 litres.
Some fuel retailers had already imposed measures of their own. Hungary's MOL, which operates petrol stations across the region, had already imposed a 30-litre limit.
