Can an off duty police officer issue a ticket?
It depends upon the laws of the state/municipality where the
Law officers in many communities are never considered "off duty"
and can issue tickets, make arrests, etc. at any time as long as
they are within their jurisdiction and circumstances warrant
(suspected DWI stop, reckless driving, etc.).
It is usually required that the officer be driving a police vehicle
when making a traffic stop and the officer must always identify
themselves as law enforcement if they are not in uniform.
