text: You are right, there is the restriction coming from C/ de la Garanona to C/ L.Rodriguez F. NOT to turn left for vehicles of 3rd order (3a clase). So I try to add: restriction=no_left_turn:conditional=yes@ (maxweight>5)
  
  however this is not correct as 3a Buses are above 5t and 3a trucks above 12t. I did not figure out yet how to express the wight limitation for different types of vehicles. For vehicles below 5t there is no condition. (the sign was again blocked by trucks and buses parking in front of).
