delivered the Opinion of the Court.
This is an interlocutory appeal by the prosecution pursuant to C.A.R. 4.1. The defendant, Jose Luis Olivas, a/k/a Sergio Olivas Ortiz, a/k/a Sergio Olivas, was charged with possession of marijuana and possession of marijuana with intent to distribute. See § 18-18-106(4), 8B C.R.S. (1986), and § 18-18-106(8), 8B C.R.S. (1986). Following a preliminary hearing, the defendant was bound over for trial on both counts. The defendant filed a motion to suppress the marijuana seized as a result of the search of the 1977 Buick he was driving even though he had consented to the search at the time of his arrest. After a hearing, the trial court suppressed the marijuana seized in the search. We reverse and remand for further proceedings consistent with this opinion.
I
On November 22, 1992, Trooper Miranda of the Colorado State Patrol stopped the defendant, who was driving a 1977 Buick, because the windshield was craсked. The stop occurred at approximately 8:00 p.m. on Interstate 25 near Colorado Springs. Trooper Miranda learned the automobile which the defendant was driving had New Mexico license plates which were not registered in New Mexico computer records. After the stop occurred, Trooper Miranda asked the defendant to produce his driver’s license. He produced a license issued by the state of Texas and told Trooper Miranda that he was en route to Denver from El Paso, Texas. He did not have registration papers or any evidence of ownership and said that the Buick belonged to Ramon Gutierrez of Las Cruces, New Mexico. The defendant also volunteered that there were some items in the glove compartment. When the glove сompartment was opened it contained no vehicle registration documents or anything to establish ownership, valid insurance coverage, or vehicle identification. Trooper Miranda issued a warning ticket to the defendant for the cracked windshield and asked whether he was carrying illegal weapons, illegal drugs, or large amounts of money. 1 *213 The defendant said “no,” and at Trooper Miranda’s request, voluntarily consented to a search of the automobile. 2
During the search, Trooper Miranda opened the trunk and saw that it contained no luggage. When Trooper Miranda inspected the automobile’s spare tire compartment, the defendant commented that there weren’t any drugs in there. The search of the automobile revealed no evidence of contraband until Trooper Miranda noticed that the panel on the left front door of the Buiek was loose and was separated from the door by one to two inches. Trooper Miranda testified that he looked behind the loose driver’s side door panel with a flashlight and without touching the panel saw plastic packages. Trooper Miranda then pulled a loose section of the panel back and observed what appeared to be plastic packages of marijuana. When the door panel was subsequently removed, small plastic packages containing forty-nine pounds of marijuana were found. The defendant initially claimed that he did not know that marijuana was hidden in the door. After he was advised of his rights and made a statement, the defendant was told thаt he could be prosecuted as a special offender if more than 100 pounds of marijuana were found in the automobile. 3 At that point the defendant replied that the automobile did not contain that much marijuana.
The primary question before the trial court was the scope of the consent given by the defendant to search the automobile which he was driving. The trial court considered significant the fact that the defendant was not advised he could refuse to give his consent to the search. The trial court also questioned whether Trooper Miranda could see behind the panel before it was pulled away from the door. After considering all of the factors involved, the trial court stated:
[T]he primary issue seems to be the scope of the search. It appeаrs to me although Mr. Olivas did consent and agreed that the car would be searched and apparently cooperated in the search of the trunk, I would not find based on the consent form I have or on any testimony that I heard that [the] consent extended to pry off the panels of the car. [The car] was basically destroyed on the inside. And I would find the officer went in fact beyond the scopе of what is an admissible search and would therefore suppress the evidence that was seized after he had pried off the panels.
It seems to me also that although it’s not required under case law, that the forms the police department use really should have the right to refuse on those forms. It appears to me that would be a lot more — I guess a lot more indicative of their intent if they would simрly state on the form, “You need not sign this form, but if you do consent, we will proceed to search at that point."
So what I would find is that the scope of the search was beyond what would be acceptable, based on the kind of consent *214 that was given in this case, therefore suppress the evidence that was seized.
II
In the absence of a clear statement that a suppression ruling is grounded оn the Colorado Constitution, as opposed to the United States Constitution, the presumption is that a trial court relied on federal constitutional law in reaching its decision.
People v. McKinstrey,
The prosecution claims that the search behind the door panels of the automobile was constitutionally permissible because it would have been objectively reasonable for the defendant to understand that by consenting to a “complete” search of the automobile, he also consented to the search of those parts of the automobile that provide places where narcotics could be hidden, such as behind loose door panels, in the crevices of the trunk, or behind the spare tire. We agree, and conclude that the trial court erred in its determination that the search behind the door panels of the automobile exceeded the scope of consent given by the defendant.

A
The Fourth Amendment to the United States Constitution protects against unreasonable searches and seizures.
Minnesota v. Dickerson,
— U.S. -, -,
The scope of a warrantless sеarch is generally defined by its expressed object,
United States v. Ross,
B
The question presented in this case is whether the defendant’s general consent to search the automobile included consent to search areas behind loose door panels that police officers believed might contain contraband. The United States Tenth Circuit Court of Appeals has consistently upheld similar consent searches of automobiles.
In
United States v. Torres,
Unquestionably, [the defendant] gave his voluntary consеnt when he signed the form which was provided him. This explained that a complete search was to be made, and thus, of course, it logically follows permission to search contemplates a thorough search. If not thorough it is of little value. A complete search was authorized, and it should have been anticipated that it would be a careful one, although the defendant may have thought that the officers might overlook the money.

In
United States v. Espinosa,
Defendant stood beside his car expressing no concern during this thorough and systematic search. The search lаsted approximately fourteen minutes. At no time did defendant attempt to retract or narrow his consent. Failure to object to the continuation of the search under these circumstances may be considered an indication that the search was within the scope of the consent,
Id. at 892.
A similar consensual search of a rear quarter panel of an automobile was upheld by the Tеnth Circuit in
United States v. Pena,
We believe these cases provide appropriate guidance on the question of a police officer’s ability to search an automobile when the person providing the consent initially agrees to a general and “complete search of [the] vehicle and contents.”

It is true that the scope of a consensual automobile search is not limitless, and that the search remains bounded by concepts of reasonableness.

When analyzed within the framework of an objective reasonableness test, the trial court’s factual determination that the search of thе defendant’s automobile exceeded the scope of his consent is clearly erroneous. Trooper Miranda, after giving the defendant a warning ticket for the cracked windshield, asked the defendant whether he was carrying illegal weapons, illegal drugs, or large amounts of money. The defendant replied in the negative. Trooper Miranda then requested, and received, the defеndant's" consent to search the automobile for those items. At that point, “a complete search was authorized and it should have been anticipated that it would be a careful one, although the defendant may have thought that the officers might overlook the [drugs].”
Torres,
Although the defendant was standing only a short distance away at the time Trooper Miranda looked behind the door panel, thеre is no indication that the defendant ever expressly or impliedly made any attempt to limit the scope of the search so as not to include the area behind the loose door panels. The defendant knew that the object of the search was illegal weapons or drugs. Smugglers of these types of items generally do not leave them scattered loosely throughout the vehicle, but instead hide the illegal products out of sight or in containers.

Under the facts of this case, the suppression order was clearly erroneous. The order is reversed and the case remanded for further proceedings consistent with this opinion.
Notes
. Once Trooper Miranda had lawfully stopped the defendant for a routine traffic violation, there was no level of suspicion required to request the defendant’s voluntary cоnsent to search the automobile. However, it is evident to us that the trooper, a fourteen-year veteran with the Colorado State Patrol, reasonably suspected that contraband was present in the automobile. The subsequent investigation suggested a particular “drug courier profile” which prompted Trooper Miranda to ask whether there was any contraband in the vehiclе and to request the defendant’s consent to search the automobile.
The defendant told Trooper Miranda that the automobile belonged to Raymond Gutierrez of Las Cruces, New Mexico, a town which is located not far from the Mexican border. The defendant, who was licensed to drive in Texas, and was driving an automobile bearing questionable New Mexico license plates, also stated that he was en route to Denver from El Paso, Texas, but he carried no luggage or other items indicative of an interstate trip, and possessed nothing oth *213 er than a jacket which was in the back seat of the automobile. Moreover, when requested to do so, the defendant could produce no evidence of ownership or right to possession of the automobile and had no spеcific knowledge of the contents of the glove compartment.
. The defendant gave his consent by signing a consent form. Because the defendant was unable to adequately read an English version of the consent form, he instead read and signed an equivalent form that was’ written in Spanish. The consent to search form provided that,
I, Sergio L. Ortiz, authorize Michael A. Miranda and Russell Wise officers of the Colorado State Patrol, to conduct a complete search of my vehicle and contents, and/or premises; MAKE: Buick; MODEL: LeSabre; COLOR: White/Red; TYPE: 4-Door; VIN: 4P69K7X115460/727AJB (NM); Located: Colo. 25; 3 Mi. S. Monument.
This written permission is being given by me to the above named officers voluntarily and without threats or promises of any kind.
The consent form was executed on November 22, 1992, at 8:30 p.m. and was witnessed by Trooper Miranda. At the time thе form was executed, the defendant gave no indication to Trooper Miranda that he did not understand the contents of the form.
. Following his arrest, the defendant also signed a Spanish version of an advisement of rights form which contained the complete advisement as required by
Miranda v. Arizona,
. The consent form the defendant signed authorizes ”[o]fficers of the Colorado State Patrol to conduct a complete search of my vehicle and contents.” The defendant signed a form containing this provision printed in Spanish.
. The trial court indicated that the police should be required to notify the suspect that he is free to withhold his consent to search and that failure to so notify the defendant suggests that the search went beyond the scope of consent. The trial court stated that "although it is not required under case law, the forms the police department use really should have the right to refuse on those forms. It appears to me that would be a lot more ... indicative of their intent if they would simply [tell the suspect that he need not consent to the search].”
As the trial court correctly stated, the police are not necessarily required to inform a suspect that he may withhold consent. The issue of notification is not relevant to the question of scope of consent, but instead relates to whether the defendant’s consent to search was voluntary.
See Schneckloth v. Bustamonte,
. Contrary to the trial court’s finding, the record indicates that Trooper Miranda made no effort to "pry off’ the door panel or door to search for drugs. Rather, whеn confronted with a loose door panel, coupled with his training and experience in the investigation of drug smuggling, Trooper Miranda pulled an already loose panel away from the door a couple of inches to look behind it. It is not unreasonable to conduct such a search in this case. We believe it is also significant that no destruction of the defendant’s property occurred as a result of the challenged search.
