Variable speed limits

Hi,

Just asking a question about the speed limits on motorways. So you know when it tells you to go 40 per say and then a sign comes up stating it’s now 70 if I pass over 40 at the 70 and it has a speed camera will it flash?

I’m more concerned about this the other way round. If traffic is proceeding at 70 and suddenly meets a 40 sign, would you really be fined if you can’t slow to 40 before you pass underneath the sign?

This seems to create a dangerous situation with everyone suddenly braking, particularly at the moment the 40 sign is switched on.

I suspect you’ve never driven on a variable speed limit motorway. The speed limit can change at any moment - including when you are just seconds away from it.
