Over 1,500 cars have been licensed across the Northern Sound region so far in 2026.
Data from the Central Statistics Office shows there's been a slight decrease on the same time last year.
The CSO's monthly report outlines the number of private vehicles licensed for the first time by make and local authority.
82 cars were licensed across Cavan and Monaghan during the month of June.
Overall, the figure is 1,556 across the two counties so far this year.
It's a drop since last year's number of 1,578 in the first six months of 2025.
Nationally, almost a quarter of new private cars licensed in the first half of 2026 were electric.
