Can stone dust damage car paint in this situation?

[Koolman511]

I was leaving the supermarket and there was a road works lorry working on the roads while I was doing about 10mph or less and probably the lorry was 5mph, I noticed the chimney of his lorry was blowing out dust and I could hear little stone/dust noises from inside car which lasted about 5 seconds before he turned. I would describe it as a windy day while little stones flying around the place or maybe on the motorway.I am worried of damaging the car paintwork

I live in the UK in Scotland

Hello

Sorry I called it a chimney because I didnt know what it was called. Here is a picture of what it looks like. I am sure it was the chimney it was blwoing out stone dusts.
