My son is almost 9 and he is not allowed to 'roam' or go to the park (two roads down) himself, but with permission he can walk up the road to his friends, and he is allowed to play in the front (street) with his bike so long as he is where I can see him. Next year I was thinking, with a friend, he can walk on his own to school (no parents). But we will be going anyways, so we will still keep a bit of an eye on him as we have our younger daughter who has autism and she won't be doing much on her own.
