Apart from seat belt checks, police will also be looking to see if children are properly seated in child seats.
The campaign – which is part of a wider European initiative by the European Traffic Police Network (TISPOL) – will run until September 17 across the island.
The aim of the campaign is lower the risk of injuries and road fatalities by motorists and passengers not using seat belts. Officers will also be checking to see if children are properly fastened inside the cars.
According to police figures, 62.6% of road fatalities were due to drivers and passengers not being properly fastened.
