In the US, as we've always seen it, “driver’s license”.
It’s a licence for a single driver, so the singular possessive, “driver’s”, is used.
In the UK, they don’t use any of those terms. They use “driving licence”.
Only the verb is spelled “license” – the noun is “licence”.
As for “driver’s” versus “driving” it’s just a difference of convention.
Essentially, they treat it as being a licence to drive, rather than a licence for a driver.
