"Sofőr" is a driver who drives car or any engine powered vehicle. "Vezető" is literally a person who leads, it's also used with vehicles but not that often. The word "vezető" alone usually sands for leader, but in compound words it can mean driver "Bus driver" = "buszvezető" but "buszsofőr" is also used.

I think ,,vezető" is correct... I am Hungarian btw
