Police have said that drivers were caught going over the speed limit on the M1 while they were protecting a family-of-five.
Cops say that a nearby speed camera flashed "a couple times a minute" after some motorists failed to slow down.
Officers were protecting the family, which included three children, whose car had broken-down in the inside lane, reports DerbyshireLive.
The lane was closed to traffic and a lower speed limit imposed for safety reasons.
Derbyshire Roads Policing Unit tweeted just after midday today and said: "M1. Watch out for the camera flash on the right hand side. Going off a couple of times a minute capturing those who have failed to slow down for us protecting five people including three kids in a broken-down car. #Traffic."
