A string of recent hit-and-run crashes on Oahu has left families grieving and demanding justice, which is bad news for road safety on the island.

• A moped rider was rear-ended and thrown onto Kamehameha Highway early this morning; the driver fled and she is in serious condition.
• A 25-year-old woman was struck and killed by a driver who took off in the Waipahu area; two weeks later, no arrest has been made and her family is speaking out.
• Police also confirmed two more recent hit-and-runs: one involving an elderly couple on the H-1 freeway, and another involving a family with a 2-year-old and a 9-year-old in the car.
• The family with young kids says they are lucky to be alive after the other driver ran red lights and sped off, and they're calling for safer driving from the community.

Outlook: Police are investigating all these cases and are asking the public for any information that could identify the drivers involved.
