Fuel warning light is on, what about the remaining distance?

‌When the fuel warning light comes on, the remaining distance is usually around 70km. (It varies depending on the vehicle)
From that point, you can drive about 70km more. (It will be similar based on your current fuel efficiency pattern.)
Some cars might stop displaying the remaining distance after driving just a few more kilometers from that point.
Even if it's not displayed, you can still go about 70km from the moment the warning light came on.
So, after driving 70km, the remaining distance actually hits 0.
Does that mean you can't drive anymore once the remaining distance hits 0?
No, you can usually go an additional 30–50km as a safety margin.
Of course, this varies by vehicle.
They say it's not good for the fuel pump system, especially in diesel vehicles.
It is better to make it a habit to refuel in advance,
but it is good to know this since emergencies can happen while driving.
It's not that you can only go 30–50km after the warning light comes on;
rather, you can go the distance indicated when the light first appeared (usually 60–70km),
and then you can go an additional 30–50km.
I'm writing this because I saw someone else's post saying you can only go 30–50km after the light comes on...
