HRS §134-9.3
Leaving a firearm in a vehicle
This law says you cannot leave a firearm in a vehicle unless it is locked in a secure container that is hidden from outside view. A locked trunk or glove box alone does not count. Breaking this rule is a petty misdemeanor.

The statute, as written — Leaving unsecured firearm in vehicle unattended; penalty
(a) No person shall intentionally, knowingly, or recklessly store or otherwise leave a loaded or unloaded firearm out of the person's immediate possession or control inside a vehicle without first securely locking the firearm in a safe storage depository that is out of sight from outside of the vehicle. (b) For purposes of this section, "safe storage depository" means a safe or other secure impact- and tamper-resistant container that, when locked, is incapable of being opened without a key, keypad, combination, or other unlocking mechanism and is capable of preventing an unauthorized person from obtaining access to or possession of the firearm contained therein. A vehicle's trunk or glove box alone, even if locked, is not a safe storage depository. (c) This section shall not apply to a person in an exempt category identified in section 134-11(a). (d) Any person who violates subsection (a) shall be guilty of a petty misdemeanor.
