The Transport Ministry's Thomas De Spiegelaere: "In 2012 we saw a slight fall in the number of kilometres covered, but the trend did not continue."
"The 2013 figure is above that for 2011. On average fewer kilometres are being covered by each vehicle, but the number of vehicles has again risen boosting the total."
The increase is noticeable in all regions.
DERV-fuelled vehicles are responsible for 78% of the kilometres driven.
The average Belgian drives 20% more kilometres than a Frenchman, 17% more than a Dutchman and 8% more than a German.
