    FAQ: Colorado Law Automobile “Inventory” Searches

    This article addresses searching a vehicle without a warrant during an inventory search.

    In discussing this exception to the Fourth Amendmentfs warrant requirement, the background, requirements, and scope of the search are addressed.

    With regard to the scope of the search, the article will focus on four specific areas:

    • the passenger compartment of the vehicle;
    • the trunk of the vehicle;
    • unlocked containers located in the vehicle;
    • and locked containers located in the vehicle.


    Inventory searches are a “well-defined exception to the warrant requirement of the Fourth Amendment.” Where evidence is found during a lawfully conducted inventory search, it may be used against the defendant in a later trial.

    In South Dakota v. Opperman, the Supreme Court outlined three justifications for allowing law enforcement officers to inventory lawfully impounded property without first obtaining a warrant.

    First, there is a need for law enforcement to protect the ownerfs property while it remains in police custody.

    Second, an inventory protects the police against claims or disputes over lost or stolen property.

    And third, an inventory is necessary for the protection of the police from potential dangers that may be located in the property.

    Because inventory searches are routine, non-criminal procedures whose justification does not hinge on the existence of probable cause, “the absence of a warrant is immaterial to the reasonableness of the search.” Instead, to be reasonable under the Fourth Amendment, “an inventory must not be a ruse for a general rummaging in order to discover incriminating evidence. The policy or practice governing inventory searches should be designed to produce an inventory.” Thus, where law enforcement officers act “in bad faith or for the sole purpose of investigation,” an inventory search will be held invalid.

    Requirements to Conduct an Inventory Search of a Car

    In order to conduct an inventory search on a vehicle, two (2) requirements must be met.

    First, the vehicle must have been lawfully impounded. There are a variety of reasons why law enforcement officers may lawfully impound a vehicle.

    As a practical matter, the contact with vehicles by law enforcement officers usually, if not always, involves the detection or investigation of crimes unrelated to the operation of a vehicle.

    In these types of cases, the law enforcement officer may arrest the individual and impound the vehicle, should there be no other person available to take control of it. State and local officers may impound vehicles for a variety of reasons unrelated to any criminal investigation.

    In the interests of public safety and as part of what the Court has called ecommunity caretaking functions,f automobiles are frequently taken into police custody. Vehicle accidents present one such occasion. To permit the uninterrupted flow of traffic and in some circumstances to preserve evidence, disabled or damaged vehicles will often be removed from the highways or streets at the behest of police engaged solely in caretaking and traffic-control activities. Police will also frequently remove and impound automobiles which violate parking ordinances and which thereby jeopardize both the public safety and the efficient movement of vehicular traffic.

    The second requirement of a valid inventory search is that the inventory be conducted in accordance with a standardized inventory policy aimed at accomplishing the justifications for inventory searches.

    The underlying rationale for allowing an inventory exception to the Fourth Amendment warrant rule is that police officers are not vested with discretion to determine the scope of the inventory search. This absence of discretion ensures that inventory searches will not be used as a purposeful and general means of discovering evidence of crime.

    While the law enforcement agency involved must have a “standardized” inventory policy, several courts have upheld unwritten standardized policies. Most law enforcement agencies have established standardized policies as regards inventory searches and most, not all, are conducted in good faith.

    Scope of the Inventory Search

    The scope of an inventory search is defined by the standardized inventory policy of the particular agency involved. As a general rule, however, inventory searches may not extend any further than is reasonably necessary to discover valuables or other items for safekeeping.

    For example, law enforcement officers are not justified in looking into the heater ducts or inside the door panels of a vehicle, in that valuables are not normally kept in such locations. The Supreme Court has upheld inventory searches of the passenger compartments of vehicles. Additionally, inventory searches of the trunk have also been found valid.

    Finally, inventory searches of containers, locked or unlocked, may be conducted, so long as the standardized inventory policy permits.
