Police stopped more than 20 drivers for no insurance in a roadside clampdown.
Officers hailed the operation held in Barking on Thursday, saying the borough was “a safer place”.
The rogue drivers face �200 fines and some could lose their licence.
Chief Insp Mike Hamer said: “The response from the public during this operation was hugely supportive.
“Uninsured drivers are more likely to be involved in criminal activity and collisions. They are also less likely to have vehicles in a safe and roadworthy condition.
“My officers worked incredibly hard during this initiative resulting in the removal of 22 uninsured vehicles and borough roads being a safer place for road users and pedestrians.”
Police stopped more than 500 vehicles at various locations including Abbey Road, Longbridge Road and Upney Lane during the crackdown named Operation CUBO.
