New figures from the Central Statistics Office show the number of goods vehicles on Irish roads rose by 8.9% in the third quarter of 2018 compared to the same time the previous year as the economy continues to grow.
The CSO said that an estimated 119,603 goods vehicles (greater than 2 tonnes unladen weight) used Irish roads in the three months from July to September.
A total of 41 million tonnes of goods was transported by road in the third quarter, an increase of 10.6% when compared with the same time in 2017, the CSO added.
The total distance covered by road freight transport in the third quarter was 423 million kilometres, today's figures show.
The commodity group 'Quarry products, metal ores and peat' represented 27.2% of all tonnes carried in the three month period.
The CSO also said that activity measured as weight by distance (tonne-kilometres) decreased by 3.3% to 2,949 million tonne-kilometres in the third quarter of 2018 when compared with the same quarter in 2017.
