Why does the text on these road signs seem to disappear when you drive underneath/past one?

Firstly, this isn’t the UK. But to answer the question, the display/LEDs are most likely angled, and directional, so it is better viewed further back, and least distraction for anyone else. You also don’t want led lights shining directly into your eyes as you’re trying to drive under it, with potentially blinding you momentarily.

The fact that it isn't the UK isn't important, the actual text on the sign isn't what I'm asking about. I'm asking about the physical sign haha. But thank you for your answer, I do appreciate it!

This picture isn’t in the UK

It's because it's personalised to you. They know you're not a great driver and don't always pay attention, so give you an extra warning of hazards. They switch it off once you've passed so as not to bother other, better, drivers

I am confused; this isn't even a UK sign

Imagine a tube with a light at the end of it. If you're far enough away from the tube you can see down tbe tube and see the light but if youre under the tube you cant because the tube is in the way.
Same idea.

They’re designed to be directional like that so they don’t distract drivers coming the other way.
