Can Police Search Your Car Without a Warrant in Maryland?

Vehicle searches often raise Fourth Amendment issues. A criminal defense lawyer can help clarify if police conducted a legal search and seizure. An illegal car search is grounds for evidence suppression.
What is the automobile exception (probable cause) for police searches?
The automobile exception holds that police can search, without a warrant, areas of a vehicle they believe contain illegal items, contraband, or evidence of a crime, as long as probable cause exists.
In your home, you can typically expect privacy and get a relatively high level of Fourth Amendment protection. Police are likely to need a warrant to search a home.
Meanwhile, automobiles reduce the expectation of privacy. Courts also recognize that people can drive off with their vehicles before police get a warrant. So, police have more leeway to search vehicles than they do homes, but absolutely must still respect your constitutional rights.
How to challenge an illegal vehicle search to get evidence suppressed
Police lacking warrants can claim car search rights in Maryland in several situations.
Plain view doctrine
Police who are lawfully present and have lawful access to the item can seize a stolen item, a bag of drugs, or an open container of alcohol in plain sight if its incriminating nature is immediately apparent. Police are not necessarily allowed to search the vehicle, but they often do, citing probable cause that a search would turn up additional evidence of the crime the object in plain sight indicates.
How to challenge: Criminal defense attorneys can take several approaches. One is to argue that the officer was not lawfully present, as could be the case if the traffic stop was based solely on race. Another is to say that the officer moved something else in order to get a view of the item in question or otherwise expanded their view.
Consent searches
If you consent—or someone else with authority over the car does—police can generally search your vehicle without a warrant.
However, Maryland law prohibits vehicle searches based solely on cannabis odor, possession or suspected possession within the personal-use amount, or cash near cannabis without other signs of intent to distribute. Evidence obtained in violation of this rule is inadmissible even if police obtained consent.
How to challenge: Many times, these searches truly are not voluntary, so that is a frequent defense. You can argue that police used threats, intimidation, or excessive pressure. Alternatively, police may have exceeded the scope of your permission, perhaps searching the trunk when you did not approve that. If another person gave permission, one approach is that the person didn’t have actual or apparent authority to make that type of decision.
K-9 sniffs (Rodriguez v. United States)
A drug-detection dog can sniff around a car during a legal traffic stop if doing so does not prolong the traffic stop. If the dog alerts, that could make for probable cause to search the vehicle. Otherwise, without reasonable suspicion or some other legal basis, police cannot keep a driver waiting at a traffic stop for a K-9 to arrive to sniff the vehicle.
How to challenge: Police illegally prolonging a traffic stop to wait for a K-9 unit to arrive is a common argument. Your lawyer can also challenge the dog’s reliability or show that officers improperly documented the search.
Search incident to arrest
After police arrest someone in a car, officers may worry about officer safety or evidence preservation, and so believe they have the right to search at least part of the vehicle. One example is during a DUI arrest. Police often search the car for open containers of alcohol (evidence preservation). Less common is when officers announce an arrest but the occupant is not handcuffed or otherwise secured and could be within reaching distance of the glove compartment or another “risky” area. Police could use that safety risk as a reason to search the glove compartment, ostensibly for a weapon.
How to challenge: One argument is that police exceeded limits, for example, if you were already handcuffed, in the police car, and had no way to access the glove compartment.
Alternatively, scope creep could be at work. Suppose police arrest you for driving with a suspended license. That is established through records, so officers reasonably wouldn’t search your vehicle for evidence related to that offense.
Inventory searches
These often occur after police decide to impound a vehicle but before the towing itself occurs. The purpose of an inventory search is to guard against claims that police lost or stole items that were in the car. However, authorities generally can seize illegal drugs, illegal guns, contraband, stolen property, and the like if found during the inventory search.
How to challenge: A major tactic is to show that the vehicle impoundment was unreasonable or that the inventory search did not follow standardized procedures. This could happen if police impounded a legally parked vehicle on a private lot and another owner could have driven it off, police never filled out an inventory sheet, or police took apart panels, which isn’t covered under typical inventory search procedures.
Likewise, if police talk about wanting to find drugs in the car and search a bit (without consent) before deciding to impound the vehicle, this may not be an inventory search but rather an illegal evidentiary search.
