Q. What are the postal procedures in delivering certified, express and other mail that requires a signature for customers living in condos?

I have already experienced three instances where I was home and no delivery was attempted, yet I received notification of certified mail for me that was not delivered.

I am living in the new Moana Pacific Condominium and must go to the Downtown Post Office to pick up that mail, even though the Ala Moana Post Office is across the street.

A. U.S. Postal Service Consumer Affairs Manager Lynne Moore said, "According to Pam Glatt at the Downtown Station, the carrier at that condominium will make an attempt to contact residents via their secure entry system if possible."

The problem is that not all entry systems list names and unit numbers, so postal workers can't always call to let you know they're downstairs.

However, at your particular building you can sign a waiver to let your resident manager accept mail for you.

Occupants of secured buildings can check with their resident managers for more information about this. Those who live in unsecured buildings should know that postal workers are not required to go up to their units if the mailboxes are in the lobby.

As for your question about why the mail goes to the Downtown Station, Moore explained that undelivered mail goes to the post office that provides delivery services and Ala Moana is only a retail office.

Q. Do the same laws that govern autos apply to motorcycles? Meheula Parkway runs behind my house in Mililani Mauka and we are barraged daily with the overbearing noise from motorcycles and their exhaust. There are also gangs of "hogs" that barrel through on weekends. Most of the noise is during the commute hours and all day on weekends.

A. Unfortunately, you might just have to close your windows. There's no law against a group of friends taking their bikes out for an afternoon ride, even if the collective noise and exhaust from the highway might be bothersome.

Police in the Traffic Division said motorcycles — Harley-Davidsons, in particular — are usually loud but are probably not above the legal limit. As for the exhaust, the state Department of Health only does long-term monitoring of large businesses. If you're concerned about one motorcycle in particular, you can call the police with the license plate number to have it checked out.
