A neighbor's car alarm goes off all night—what can I do?
Call DeSoto Police non-emergency. Officers can contact the owner; if the alarm continues excessively, a citation or abatement may follow.
Can I be fined for my own car alarm going off?
Yes, if it activates falsely and repeatedly or sounds for extended periods. Keep your alarm properly calibrated and respond quickly when it triggers.
