Northern Ireland haulier TJ Hood Transport has been fined £2,700 after committing a string of tachograph and drivers' hours breaches.
In a hearing at Antrim Magistrates Court, the operator, based in Crumlin, Co Antrim, pleaded guilty to 13 sample charges.
It was fined £200 for each offence of failing to produce tachograph records to transport officials and failing to ensure the return of tachograph records from drivers.
A further fine of £300 was imposed on the firm for failing to make regular checks and organise drivers' work to ensure compliance with tachograph regulations.
In 2010, officials from the Driver and Vehicle Agency (DVA) in Northern Ireland wrote to TJ Hood Transport seeking tachograph records for 16 vehicles over a six week period for the purposes of analysis.
However, records for four vehicles and five drivers were not produced.
An analysis of the tachograph records that were produced revealed some 207 infringements including insufficient daily rest, insufficient weekly rest, excess daily driving, excess weekly driving, failure to take a 45 minute break and failing to use tachograph equipment properly.
The DVA brought the charges under the Passenger and Goods Vehicles (Recording Equipment Regulations NI) 1996 and Article 81(2) of the Road Traffic (NI) Order 1981.
