Provides that a violation is subject to a civil penalty not to exceed $500. Provides that a violation is subject to a civil penalty not to exceed $1,000 if any person knows or reasonably should know that a minor, an at-risk person, or a prohibited person is likely to gain access to a firearm belonging to or under the control of that person and a minor, an at-risk person, or a prohibited person obtains the firearm. Provides that a violation is subject to a civil penalty not to exceed $10,000 if a minor, an at-risk person, or a prohibited person obtains a firearm and uses it to injure or cause the death of a person or uses the firearm in connection with a crime.

Changes the age of a minor from under 14 to under 18 years of age for which it is unlawful, with certain exception, for any person to store or leave, within premises under his or her control, a firearm if the person knows or has reason to believe that a minor who does not have a Firearm Owner's Identification Card is likely to gain access to the firearm without the lawful permission of the minor's parent, guardian, or person having charge of the minor, and the minor causes death or great bodily harm with the firearm.
