The galaxy is definatly not classed as a van, it is a "Private light vehicle" class vehicle, you would not get away using the lane in the tunnel as you would need to remove all your rear seats and have company logo on sides of car to prove its "van" status and tax disk would need to verify as" Private light vehicle". I am willing to be proved wrong on this, but would have to say if I was sitting in a que of traffic in the tunnel and you whizzed by in your galaxy, I would be pretty well Pi**ed off. Hope this helps!!
