This lesson provides guidance to Iowa law enforcement officers on the following topics:

• Is an out-of-state medical marijuana registry identification card a valid prescription or order that constitutes a defense to a possession of marijuana charge in Iowa?

• What factors show consent to a search, and does the Iowa Constitution protect a right to be advised of a right to refuse a search?

• Will briefly crossing the fog line on a roadway provide reasonable suspicion to justify a vehicle stop for operating while intoxicated?

• May an officer stop the operator of a utility vehicle (UTV) without first having reasonable suspicion of criminal activity or probable cause of a traffic violation?

• When does the possibility of an imminent destruction of evidence justify an officer’s warrantless entry and search of a suspect’s home?
