(a) Every person who owns, possesses, purchases, or acquires a firearm, as that word is defined at Section 451(d) of this chapter, shall be responsible for the safe storage of the firearm.
(b) Any person who owns, possesses, purchases, or acquires a firearm, as that word is defined in section 451(d) of this chapter, whose failure to lock or safely store the firearm directly results in a person not licensed to own or possess the firearm to gain access thereto, and said unlicensed person injures or kills himself or another person with said firearm, may be, upon conviction, punished by a fine not to exceed $2,500, imprisonment not to exceed two years, or both, and be subject to forfeiture of his license and firearm. This section shall not be construed as precluding the charge or conviction of any other appropriate violation of law.
(c) It is unlawful to leave a firearm in a motor vehicle unless it is stored in an approved vehicle firearm lockbox. A conviction for violation of this subsection subjects a person to the penalties set forth in subsection (b) of this section.
(d) For purposes of this section, “safe storage” means the storage of a firearm in a locked manner so as to prevent discharge or the storage of a firearm in a safe location that is inaccessible to all except the licensed owner of the firearm. For purposes of this section a firearm is locked when the device installed on it or incorporated into its design is activated or set to prevent the firearm from being discharged.
