In the distant past I have called 999 for big things on the motorway lane ( think whole tyres, bushes fallen off a lorry etc).
Now I would call 101, but recently after not being able to get through on three attempts after seeing a wheelbarrow of the middle lane I gave up)
I saw a complete tyre on the motorway way and didn’t call anyone as I wasnt sure who to call ( I’m always a passenger when I call).
What do other people do?
