Hope this is in the right place.
since Christmas day when a family who recently moved into the street bought their 2 teenage boys (age 13 and 16) Mopeds, everyone on the street has been plagued by them going up and down (or round and round - it's a cul-de-sac) from around 10.30 in the morning until after 11 at night. It's not just the 2 boys, they have introduced a gang of friends who take turns, along with a couple who also got motorised go-karts. The noise as you can imagine is enough to drive anyone mad(particularly the night-shift workers who live here) but also cars have been damaged by them crashing, gardens getting torn up as they just go right over them, but also safety issues, they are either on the road causing cars to swerve/brake or on the pavements with no consideration for pedestrians/smaller children. A neighbour living directly opposite them did try to appeal to the parents as they are trying to sell their own house but were met with not exactly abuse but certainly were told they had no intention of asking the kids to be more considerate.
I was under the impression that to ride a moped the minimum age was 16 and must have a learner licence so would it be worth making an anonymous complaint to the Guarda in the hope a visit from them might work, the local council will not act unless a formal complaint is made and naturally people do not want to be singled out as the complainant
TIA
