In aviation, ground effect is the distance from the ground up to 1/2 the wingspan of the aircraft in question, where aerodynamics behave quite differently than they do higher up.
There's no wingspan for us wheeled landlubbers so I'd say if it's on the ground, it's in ground effect.
Aerohead talks about ground effect somewhere in here IIRC.
