VOSA has collected more than £500,000 in deposit payments during the first quarter of its Graduated Fixed Penalties (GFP) scheme, and has seized 800 vehicles.
A total of 11,000 GFPs have been issued since 28 May - of these, 60% were given to drivers of non-UK vehicles.
Fines range from £30 to £200 per offence, including overloading and mechanical defects.
Where a driver is unable to provide a satisafactory UK address, full payment is taken immediately as a deposit.
"The results of this first quarter are encouraging," says Karen Farr, VOSA GFP scheme manager. "This scheme enables us to level the playing field for all UK and foreign drivers.
"We have already started to see an improvement in compliance, and that is good news for operators, drivers and road safety in general."
During the first 12 days of operation 
of the GFP initiative, VOSA took more than £80,000 in fines - 88% of which came from foreign drivers of vehicles in breach of the UK's road transport laws.
In addition, on 2 September, Essex Police discovered 23 truckers were breaching drivers' hours or driving an unroadworthy vehicle. Two vehicles were seized, while another was impounded by the UK Border Agency.
The crackdown, called Operation Mermaid, is a joint operation between UK police forces and VOSA to improve road safety.
"This was another successful operation for us as we continue to ensure our roads are kept safe," reports PC Harry Sexton. "A staggering 331 drivers' hours infringements were discovered, which demonstrates that drivers 
and firms still need to improve road safety and stop putting lives at risk."
