Should I use a primer before painting driveway with special paint?

I would check the directions and/or the manufacturer's website.

If it's a concrete paint - we have used that in our basement and garage and didn't add a primer. For your driveway since it gets more weather changes that it will deal with, I found an article that might be helpful - https://modernize.com/home-ideas/17680/primer-the-go-between-for-paint-and-concrete - good luck

You are painting what ever the top surface is. If it is already painted you are painting paint. If it is raw asphalt, no expensive specialty paint needed, just paint with any exterior solid body paint, that is it's own primer. Primer just means first coat, nothing more. Most surfaces can be primed with the paint you are using for the final coat, in other words just paint more than 1 coat. If it is freshly sealed concrete, ask the paint store what to use on freshly sealed concrete. Don't know what the surface is, so can't advise any further than that.
