Car production fell by 58.7 per cent during January, which could concern vehicle dealerships with business insurance.
Figures produced by the Society of Motor Manufacturers and Traders (SMMT) show the total number of units produced last month fell to 69,755.
The number of commercial vehicles fell by 59.9 per cent to 8,351, which the organisation describes as a "substantial fall".
Paul Everitt, the SMMT's chief executive, claims the decreases are in line with expectations following winter shutdowns, which could interest business insurance holders.
He states: "The extent of the decline highlights the critical need for further government action to deliver the measures already announced and ease access to finance and credit."
Mr Everitt highlights the record percentage of output allocated to export, stating the 83.5 per cent of vehicles being sold abroad shows the effectiveness of scrappage incentive schemes.
Last week, sector organisation the Retail Motor Industry Federation announced it would be examining the benefits it confers on its members.
