Take the metro to the end station ''La Poterie''. From here, it is about 1 km walking to the spot. Start walking on ''Rue de Vem'' to the south. To the left you will pass a huge parking place. Go past one roundabout cross the bridge over the motorway to get to the roundabout on the other side. From this roundabout, there is an exit going on the motorway in the good direction, with a nice place for cars to stop. Use a sign with Laval written on it, if your driver don't want to pay for the toll you can ask him to drop you at the last exit before it from there you can simply walk to the toll station.

Another option is to go to ''Noyal sur Vilaine'', there a transport company operate you can just ask truck driver at the gate or hitch on the entrance of the motorway next to it.
