I don't think it's a good idea to ask what somebody else's truck does when it's your own Low Fuel Light that's on.
What if I told you I can go 175 miles after the Light comes on, how does that help you?
You know you have a 25 gallon tank.
When the Light comes on pull into a station and "Fill Up".
Your tank now has 25 gallons.
But wait! Look at the pump. How many gallons did you put in?
25(Full Tank) - (whatever the pump says) = (the number of gallons in your tank when the light came on)
Part B:
Reset you trip odometer before you leave the pump.
The next time you fill up.
Divide the miles on the trip odometer by the number of gallons you purchased.
(this only works if you fill up)
The answer is your MPG.
Now you know two things.
How many gallons are left when the light comes on
and how many miles you can go because you know your mpg.
Afterall your first question was, "how many miles can a truck go after the light comes on?"
The only people who truely know the answer to that are those who have run out of gas.

Some of this thinking is really funny!
The amount left in the rank is usually between 3 and 5 gallon.
How far you can go to run-out, is a function of the mileage the motor gets.
Empty running is one thing, towing a load is another.
Not even close. If running empty and you get 14 mpg then you might expect 14 x 5 gal = 70 miles but don't press your luck unless you have 5 gal along to find out.
Also, the dash micro processor determines when the lamp comes on and where the needle position is plus any inaccuracy.
The gas gauge is not updated for level on an instant continuing basis either but done in time intervals. That's why you can't see the gas gage rise while filling the tank until the motor is started and the dash gets the new level signal..
