They released this warning for drivers:
"It is vitally important to obey the overhead signs on smart motorways to ensure everyone’s safety.
See a red ? The lane is closed.
This can often be set far in advance of an incident to help those who are dealing with it.
Make sure to leave gaps in the traffic to allow people to filter into an open lane.
Driving in a closed lane could result in a fixed penalty of up to £100 and three points."
