More than 1,000 fines have been slapped on unsafe lorries since a crackdown began in London 15 months ago.
The Industrial HGV Taskforce, funded by Transport for London and the Department for Transport, has issued 1,013 fixed penalty notices since October 2013.
Officers from the taskforce conduct a variety of spot checks, including vehicle tyres, steering, brakes and loads, as well as driver and operator licences and working hours.
London transport commissioner Peter Hendy (pictured) said: “These enforcement results send out a clear message to everyone concerned that we will not put other road users, cyclists or pedestrians at risk through the actions of the minority of negligent operators and drivers in the capital.
“We will continue to work with the freight and construction industries to ensure safer vehicle operation across the capital and will push for the toughest penalties for anyone caught acting illegally.”
