delivered the Opinion of the Court.
In this interlocutory appeal, the People challenge a suppression order of the Arapahoe County District Court (trial court). The *62 trial court found that Sylvia Joy Dumas (defendant) consented to a search of her motel room for drugs, contraband, and weapons. However, the trial court concluded that the search of a checkbook, which produced other incriminating evidence, was unconstitutional. As a result, the trial court suppressed the evidence and statements made by defendant regarding the evidence. We reverse and remand.
I.
On July 18, 1996, Officer William Revelle and Officer Brian Saupe of the Aurora Police Department received an anonymous tip that drug activity was taking place in defendant’s room at the Heaven on Earth Motel. They knocked on defendant’s door and asked if they could search her room for drugs, contraband, and weapons. Defendant consented and allowed the officers to search her room. During the search, Officer Saupe discovered a shoe box containing over $1,000 in United States postage stamps. When asked about the stamps, defendant said that they had been given to her by a friend named Kid, who no longer needed the stamps because he had gone out of business. Continuing the search, Officer Saupe found a checkbook between the mattresses of defendant’s bed. He opened the checkbook and noticed that the checks were inscribed with the name Anita Foxworth. 1 He also found two sales receipts from the United States Post Office inside the checkbook, indicating the purchase of over $1,000 in stamps. 2
After seizing the checkbook and the receipts, the officers placed defendant under arrest on two outstanding warrants unrelated to this case. Although defendant was released shortly thereafter, she later turned herself in on a probation violation. While in custody on August 16, 1996 defendant spoke to Officer Jim March regarding the postage stamps. After Officer March gave the required Miranda warnings, defendant admitted to purchasing the stamps with the invalid checks. 3 She also admitted that she later went to another post office branch and exchanged $320 worth of the stamps for cash. As a result, defendant was charged with theft and forgery.
Defendant filed a motion to suppress the evidence discovered in the checkbook and her statements to Officer March. The trial court found the checkbook search unconstitutional and granted defendant’s motion. Although the court noted that there were several valid reasons for searching the checkbook, it concluded that Officer Saupe “was not looking for contraband, weapons, or drugs when he opened up the checkbook.” As a result, the trial court suppressed the evidence in the checkbook and the statements made by defendants products of an illegal search.
II.
The Fourth Amendment to the United States Constitution protects against unreasonable searches and seizures.
See People v. Olivas,
A warrantless search conducted on the basis of consent is limited by the terms given by the consenting party.
See People v. Herrera,
Besides consent, another well-established exception to the warrant requirement is the “plain view” doctrine.
See Coolidge v. New Hampshire,
A.
The validity of the officers’ entry into defendant’s motel room is not in dispute. The trial court found that Officers Revelle and Saupe properly approached defendant’s room and that defendant voluntarily allowed the officers to enter. Once inside, Officer Re-velle asked defendant if they could search the room for drugs, contraband, or weapons. The trial court found that defendant voluntarily consented to the search and that the scope of her consent was limited to drugs, contraband, and weapons.
B.
The key question in this case is whether the officers unconstitutionally exceeded the scope of defendant’s consent by searching the checkbook. The trial court concluded that the search was unconstitutional. In our view, the search was properly within the scope of consent. 4
The scope of consent is determined by “objective reasonableness” — what a reasonable person would have understood by the exchange between the officer and the suspect.
See Olivas,
C.
While defendant did not expressly consent to a search for postal receipts and other evidence in the checkbook, the trial court found, and we agree, that once the checkbook was opened, the seizure of this evidence was justified by the plain view doctrine.
See Torand,
III.
We hold that the search of the checkbook conformed to the scope of consent and that the evidence discovered in the checkbook was legitimately seized. Therefore, we also hold that defendant’s state *65 ments were not the product of an illegal search. Accordingly, we reverse the trial court’s suppression order and remand for further proceedings consistent with this opinion.
Notes
. Anita Foxworth was never identified. The Seattle, Washington address on the checks was not legitimate, and the Seattle bank that had issued the checks no longer existed.
. Defendant claimed that she had never seen the checkbook before. However, after Officer Saupe discovered a credit card in the name of Anita Foxworth, defendant stated that she found the credit card inside the checkbook.
.Check No. 3702 from the checkbook was used to purchase $640 in stamps, and check No. 3703 was used to purchase another $640 in stamps.
.The People claim that defendant does not have standing to raise a constitutional challenge to the search because she is not the rightful owner of the checkbook. However, a defendant can challenge the constitutional legitimacy of a governmental search, if the defendant has a legitimate expectation of privacy in the area searched.

v.
Naranjo,
. In some situations, a police officer’s subjective intent may be relevant.
See People v. Rodriguez,
. This was the scope of consent assumed by the trial court in upholding the shoebox search and the mattress search. The trial court found that the search of the shoebox was within the scope of consent because "certainly a shoe box could contain any one of those three things being searched, drugs, contraband, or weapons.” Similarly, the court determined that the search of the mattresses was within the scope of consent *64 because "that is probably a common hiding place that police officers know to look for contraband, drugs and weapons.” In upholding these searches, the court made no attempt to determine whether the officers were actually looking for these specific items. Rather, it found that the searches were proper because drugs, weapons, and contraband could be concealed in the items searched. This reasoning applies with equal force to the checkbook.
. Officer Saupe explained that he had previously encountered drug evidence in small containers:
ATTORNEY: Can you explain to the court whether it's true or not that you on occasion find ... narcotics in small places?
SAUPE: Yes, sometimes in small places.
ATTORNEY: Can you explain that to us a little bit?
SAUPE: Narcotics such as rock cocaine. I mean, a small rock could weigh, you know, less than a gram and can fit into the, you know, end of a ball point pen or, you know, anything that small. So narcotics can be hidden anywhere, basically.
. In
Billington,
police obtained defendant's written consent to search his hotel room for a specific bundle of documents. Inside the bundle, police discovered several check stubs corresponding to checks allegedly forged by defendant. We held that the check stubs were properly seized under the plain view doctrine, noting that "the officer was not required to close his eyes to the incriminating evidence plainly visible to him.”
Billington,
191 Colo, at 326,
Similarly, the defendant in Torand consented to a search of his apartment for a shotgun and a camera. During the search, one of the investigating officers opened a shaving kit and discovered a high school class ring. After determining that the ring had been stolen, police obtained a warrant and seized the ring. We held that even though the defendant did not consent to a search for the ring, the seizure of the ring was justified, provided that it was reasonable for the officer to search for the camera inside the shaving kit.
.The "immediately apparent" requirement means that the officer has probable cause to believe the evidence is incriminating.
