A jury found Juanita White guilty of two counts of transporting illegal aliens from Mexico into the United States. White contends that the district court erroneously denied her motion to suppress certain evidence as the fruits of an illegal search. We affirm the conviction.
FACTS AND PROCEDURAL BACKGROUND
White was stopped at the San Clemente checkpoint in the early evening on Monday, February 6, 1984. A Border Patrol Agent observed that her car “was riding low in the rear.” He noted that White, an attractive woman driving alone in a nice car, matched the common profile of drivers used by alien-smugglers. The agent approached White’s car and pressed down on its trunk several times. 1 He found that the shocks were stiff, a condition which in his experience was common when a trunk was heavily loaded with people. He directed White to the secondary inspection area. There, she consented to a search of the trunk. Three undocumented aliens were found in the trunk. She was arrested and, several days later, indicted on two counts of smuggling illegal aliens in violation of 8 U.S.C. § 1324.
DISCUSSION
White asserts that her fourth amendment rights were violated during primary inspection by the agent’s application of pressure to her vehicle’s exterior. She does not contest the district court’s finding that she validly consented at secondary inspection to a search of the trunk. Nevertheless, we must consider the propriety of the agent’s actions at the initial stop.
Cf. United States v. Cortez,
Under
Martinez-Fuerte,
the border agent was authorized to stop White at primary inspection even absent “individualized suspicion.”
Martinez-Fuerte,
The degree of protection supplied by the fourth amendment in this context is influenced by the setting — here, an automobile stopped at a permanent border checkpoint.
See United States v. Johns,

I. Degree of intrusion upon White’s fourth amendment rights.
For the first part of the balancing inquiry, we note that the fourth amendment protects White’s interests in privacy and personal security in the context of a vehicle stop by the Border Patrol.
See Martinez-Fuerte,
White chose to drive the vehicle over the public highways. She thus undermined her privacy expectation in any information which was thereby disclosed about the vehicle.
See United States v. Knotts,
The agent did not observe White’s car in motion, however, and his action cannot be justified as intended to enforce highway rules, since its goal was to investigate potentially criminal activity.
See Brignoni-Ponce,
In considering the extent of the intrusion upon White, we also note that the agent’s application of pressure to the vehicle was narrowly tailored to investigate the low ride of the car as one of the circumstances which provoked his suspicion. This limitation, as commanded by
Brignoni-Ponce,
was triggered by specific observations which caused the agent to suspect wrongdoing and was confined to the specific circumstance he observed.
We look next to the line of fourth amendment cases in the automobile context. We note-that to identify a vehicle, officers may scrutinize its exterior to the extent of scraping off a paint sample and making a cast of the tire tread — and neither action will constitute a “search.”
Cardwell v. Lewis,
Yet a decision whether this action constituted a “search” is not essential to resolve this case, for we may affirm the district court’s decision that White’s fourth amendment rights were not violated if the agent’s action was a reasonable intrusion. We therefore proceed to analysis of that issue, assuming arguendo that a search occurred.
II. Considering the intrusion in the context of the public interests it served.
In this part of the balancing test, we evaluate the circumstances of the agent’s action in the context of the public interests served by such a practice.
Martinez-Fuerte
set forth the public interests relevant to the permanent checkpoint: to control the flow of smugglers and illegal aliens,
The alternatives open to the agent would not have furthered the public interests stressed in
Martinez-Fuerte.
One possibility would have been to refer all low-riding vehicles to secondary inspection. Or the agent could have requested surveillance of White’s vehicle, after it left the checkpoint, to ascertain whether the car bounced over bumps. Third, as White would doubtless have preferred, he could have allowed her to pass through the checkpoint without further inspection. Referring all low-riding vehicles to secondary inspection would increase ■ the burden on the legitimately travelling public,
see Martinez-Fuerte,
CONCLUSION
The balancing analysis appropriate for an automobile stop at a permanent border checkpoint demonstrates that the intrusion upon White was minimal, and that the public interests served by the action are significant. Given the agent’s articulated reasons for the suspicion which caused him to press down upon White’s car, we hold that this intrusion did not violate White’s rights under the fourth amendment.
AFFIRMED.
Notes
. The government alleges that White's response to the agent’s initial bounce on the car — she pulled the car forward — increased his suspicion. Since White challenges only the agent’s pushing down on the car, not the referral to the secondary inspection area nor the consensual search there, we do not consider White’s reaction in assessing the propriety of the agent’s action.

Hernandez
had been locked and checked with an airline,
. Two recent Supreme Court opinions have held that specific "limited intrusions” were not searches.
