Yes. There are numerous circumstances under which a search may lawfully be made without a warrant. Some general areas of exception where a search can be made without a warrant are:

(a) if the safety of the police officer is involved,
(b) whether the police are in "hot pursuit" of a criminal,
(c) when they see illegal evidence in plain view from a place they have a right to be,
(d) if they are doing temporary questioning,
(e) if a person consents to being searched,
(f) if they have made a lawful arrest, or
(g) if they have reasonable cause to believe they must enter a home, building or vehicle without a warrant because someone inside is in danger.
