More than 120 drivers are being prosecuted for speeding after a two-month Kent Police operation to crack down on crashes involving commuters.
Police targeted the main commuting roads in and out of London - the M2, M20 and A2 - during rush hour throughout June and July.
Officers said the top speed they recorded was 125mph.
Action is being taken against 123 people accused of driving with excessive speed.
'Rushing to work'
Police also issued 45 fixed penalty notices, handed out 22 notices for vehicle defects, and advised 337 motorcyclists about safer driving.
Pc Dave Greenwood, who led the operation, said: "Motorists are often in a hurry to get to and from work but this doesn't excuse careless and dangerous driving."
The Kent Police motorcycle team carried out the operation, using unmarked and marked motorbikes and marked police cars to tackle speeding, anti-social behaviour on the road, and other traffic-related offences.
The force said about six people are killed on Kent's roads each month with many more seriously injured.
