Alberto Samaguey appeals his conviction for possession with intent to distribute marijuana in violation of 21 U.S.C. § 841(a)(1). While driving northbound on Texas Highway 118 about 80 miles from the Texas-Mexieo border, Samaguey was stopped by border patrol agents for an immigration check. The district court denied Samaguey’s motion to suppress the evidence found during the stop and concluded, after a bench trial, that Samaguey was guilty as charged. We affirm.
I
On December 19, 1997, a radio operator at the Marfa Sector Headquarters spotted sensor hits, indicating a northbound car on Highway 118. The first activated sensor was about 20 miles from the border and 40 miles south of Alpine. The operator notified Border Patrol Agents Casey Smart and Francisco Lopez. They were working the 11:00 p.m. to 7:00 a.m. roving patrol shift on Highway 118 south of Alpine, Texas, and Highway 385 south of Marathon, Texas.
The agents parked their marked patrol car perpendicular to Highway 118, about five miles south of Alpine. At approximately 5:45 a.m., the agents saw a two-door 1988 Honda Accord approaching. Agent Smart turned on his headlights as the Honda neared, and the Honda slowed down. The agents observed a lone Hispanic man, later identified as Alberto Sam-aguey. The agents testified that they were familiar with the few locals but did not recognize the Honda’s driver. Agent Smart testified that Samaguey did not look at the border patrol car as he passed it. The agents testified that, in their expert *197 ence, a lone Hispanic driver coming up Highway 118 at that time was either smuggling illegal aliens or drugs.
Agent Smart followed the Honda and drove closer to check the license plate. At some point during the pursuit, the Honda swerved, then continued at a speed of 45 miles per hour, slower than the posted limit. Agent Smart testified that it was common for drivers with alien or narcotic loads to slow down while an officer followed them. The agents thought the driver was nervous, which in their experience indicated the driver had something to hide. The agents noticed that the Honda had dust and dry mud on it. The registration check indicated that the ear was registered to Maria Lagunas of New Mexico. The agents thought it was strange for a lone male to be driving an out-of-state female’s car. They did not think Samaguey looked like a tourist, and they did not notice any stickers indicating the Honda had been at Big Bend National Park.
Three miles south of Alpine, Agent Smart decided to perform an immigration check. The driver, Samaguey, identified himself as an American citizen. Agent Smart testified that Samaguey appeared nervous; he tightly gripped the steering wheel throughout the questioning and spoke in a shaky voice. Samaguey told Agent Smart that he was coming back from visiting Ms girlfriend in Lajitas, which he mispronounced as “Letas,” and that he had borrowed the car from his friend, Edward Santose of New Mexico. Agent Smart testified that it was common that vehicles smuggling aliens and narcotics be borrowed and not registered to the driver. Agent Smart noticed only one key in the ignition — no key chain or ring, another common characteristic for smuggling operations.
Agent Smart asked if he could search the vehicle, and Samaguey consented. Agent Smart asked Samaguey if there was anything in the car that he should know about, and Samaguey responded, “I don’t know anything.” This response made Agent Smart suspicious. As he was looking in the car, Agent Smart noticed the panels on the side of the back seat were loose. He pulled them back and discovered several packages containing marijuana.
Samaguey was charged with possession with intent to distribute marijuana. He moved to suppress the marijuana seized by the roving Border Patrol, contending that the stop was made without reasonable suspicion and that the seized marijuana was the fruit of the poisonous tree. His motion was denied, and, on April 27, 1998, he was sentenced to one year and one day imprisonment.

This court reviews a district court’s purely factual findings for clear error, viewing the evidence presented at a pretrial suppression hearing in the light most favorable to the prevailing party, in this case the government.
See United States v. Inocencio,
III
Under
United States v. Brignoni-Ponce,
*198 (1) proximity of the area to the border;
(2) known characteristics of a particular area;-
(3) previous experience of the arresting agents with criminal activity;
(4) usual traffic patterns of that road;
(5) information about recent illegal trafficking in aliens or narcotics in the area;
(6) the behavior of the vehicle’s driver;
(7) the aspects and appearance of the vehicle; and
(8) the number, appearance and behavior of the passengers.
United States v. Aldaco,
We first consider “whether an arresting agent could reasonably conclude that a particular vehicle originated its journey at the border.”
Inocencio,
The arresting officers were knowledgeable and experienced. Agent Lopez had served as a border patrol agent in Alpine for about ten years and Agent Smart for about seven months.
See Villalobos,
Agent Lopez testified that little to no traffic comes up Highway 118 at the time Samaguey was traveling. Although traveling at an unusual time of day alone may not give rise to a reasonable suspicion, it is a permissible consideration.
See Villalobos,
The driver’s behavior is another important consideration in determining reasonable suspicion.
See Aldaco,
Samaguey’s swerving on the road could have indicated a nervousness or preoccupation with the patrol car which followed him. The record, however, is not clear about whether Samaguey swerved when the patrol car approached him to read his license plate, hardly suspicious, or if he swerved after the patrol car dropped back, which could reinforce the officers’ suspicions about a driver’s level of nervousness.
See Jones,
Finally, we are not persuaded that the appearance of Samaguey’s car supported the agents’ suspicions. The dry mud on his car was not indicative of a recent river crossing, and the agents admitted that a Honda was an unlikely car to cross the Rio Grande.
We conclude that the totality of the circumstances established reasonable suspicion for the agents to stop Samaguey’s ear. The agents had reason to believe that Samaguey’s journey originated at the border, and they noted that Samaguey was traveling alone, in an out-of-state car, registered to a female, at an unusual hour, on a road known for illegal activity. Their suspicions continued as they followed Sam-aguey, who drove too slowly after spotting the patrol car and may have swerved as a nervous reaction. Therefore, the district court properly denied Samaguey’s motion to suppress.
The judgment of the district court is AFFIRMED.
