I'd say try it, thats the only way you'll know for sure. I drove 40 ft rigids & artics for years on removals & to be honest most of the time an artic can be easier to get into driveways. If she don't go in backwards then try driving from the opp side of the road slightly past the driveway entrance then reverse & shunt until you can hook the front end into the driveway. This sometimes works as you can hang the arse end over the ditch & push it into the trees giving you a couple of valuable feet. If you do drive in get some thick ply to put over the grass so you can drive accross it without getting stuck thus allowing the rear axle to pass the gate post.
