Footers for a long drive.

I need to pour a driveway 2 meters wide by about 50 meters long. The drive is pretty straight but has some rise and fall. Is 4 inches thick enough with rebar? Are footers required or just a gravel bed and how think the gravel?

Thanks

Drive Way

What type of vehicle(s) do you have?

Two meters is not wide enough for normal sized (US) automobiles.

The gravel base also depends on the soil type the concrete is getting poured over. Rocky or hard ground won't need as much gravel as sandy or clay ground would. A driveway doesn't really need a footer but it doesn't hurt to make it a little thicker around the perimeter.

Two meters is plenty wide for my multicab and just wide enough for the small cars and taxis we have here. Think like a Toyota or Honda 4 door. I think I measured my truck at 1.6 meters and I know have passed other multicabs on the 3.5 meter road which is on the way to my property.
Multicab:

As you can figure it weighs little as 2 men can pick the back end up and move it if it's in the way of someone getting out and I'm not there. I want the drive strong enough that if some idiot in a cement truck with 10 meters of concrete drives over it. Is 4 inches enough or should I use 6?

Well, it's fairly hard and rocky I'd say. We dug some post holes for a barbed wire fence supported by bamboo posts and it was quite difficult and included a lot of use of a spud bar to break through the stones and hard earth. Would 4 inches of gravel and 4 inches of concrete be enough?
