On August 27, 2002, Defendant-Appellant, Ygnacio D. Zabalza, entered a conditional guilty plea to possession of approximately 250 pounds of marijuana with the intent to distribute, in violation of 21 U.S.C. § 841(a)(1), reserving his right to appeal the district court’s denial of his motion to suppress. Defendant filed a timely notice of appeal. We exercise jurisdiction pursuant to 28 U.S.C. § 1291 and AFFIRM.
I. Background
On January 26, 2002, Kansas Highway Patrol Sergeant Terry Kummer was traveling eastbound on Interstate 70 when he came upon a late-model blue Mercury Marquis. The Marquis was in the right-hand lane, traveling slower than Sergeant Kummer, so Sergeant Kummer moved to the left-hand lane. While following the vehicle, Sergeant Kummer observed it twice cross over the center line of the lane in which it was traveling. Sergeant Kum-mer stopped the vehicle for failing to maintain a single lane of traffic. According to Sergeant Kummer, the weather on this particular day was overcast with some wind, but, in his judgment, the weather would not have made it impracticable for a driver to maintain a single lane of travel. Sergeant Kummer had no difficulty maintaining a single lane and had not seen other drivers having difficulty.
Sergeant Kummer approached the driver’s side of the vehicle and spoke with its only occupant, Defendant Zabalza. Sergeant Kummer told Zabalza that he was just making sure that Zabalza was not sleepy and asked to see Zabalza’s license. Zabalza produced an Arizona driver’s license. Sergeant Kummer testified at the suppression hearing that when he began talking to Zabalza he detected a “moderate to strong odor” of raw marijuana coming from the car and that he had no doubt there was marijuana in the car. 1 After a brief exchange between Sergeant Kummer and Zabalza, Sergeant Kummer opened the trunk and found numerous large brick-shaped packages in brown wrapping containing marijuana.
II. Discussion
A. Standard of Review
When reviewing a district court’s denial of a motion to suppress, we defer to the district court’s findings of fact unless they are clearly erroneous.

United States

v. Horn,
B. Whether Sergeant Kummer’s Search of Zabalza’s Vehicle and Seizure of the Marijuana Was Constitutional Under the Fourth Amendment
In reviewing the constitutionality of traffic stops under the Fourth Amendment, we conduct a two-step inquiry. First, we must determine “whether the officer’s action was justified at its inception.”
United States v. Gonzalez-Lerma,
i. The initial traffic stop
“[A] detaining officer must have an objectively reasonable articulable suspicion that a traffic violation has occurred or is occurring before stopping [an] automobile.”
Soto,
Based on the above, we conclude that Sergeant Kummer’s initial stop of Zabalza
*1259
was reasonable under the Fourth Amendment.
See Ozbirn,
ii. The investigative detention and subsequent search of the trunk
“During a routine traffic stop, the detaining officer may request a driver’s license and vehicle registration, run a computer check on the car and driver, and issue a citation.”
Soto,
[f]urther questioning is permissible in two circumstances. First, the officer may detain the driver for questioning unrelated to the initial traffic stop if he has an objectively reasonable and articu-lable suspicion that illegal activity has occurred or is occurring. Second, further questioning is permissible if the initial detention has become a consensual encounter. Gonzalez-Lerma,14 F.3d at 1483 .
In this case, the district court found credible Sergeant Rummer’s testimony that when he first began talking to Zabalza he detected a “moderate to strong odor” of marijuana coming from the vehicle.

“Determinations of witness credibility [are] review[ed] for clear error.”
United States v. McRae,
An officer’s detection of the smell of drugs in a vehicle is entitled to substantial weight in the probable cause analysis.
United States v. West,
III. Conclusion
Based on the foregoing, we AFFIRM the district court’s denial of Zabalza’s mo *1260 tion to suppress and AFFIRM his conviction under 21 U.S.C. § 841(a)(1).
Notes
. The district court found Sergeant Rummer's testimony credible. Specifically, the district court stated:
[T]he court finds credible the officer's testimony that he observed what appeared to be a traffic violation when the defendant's car twice crossed over the lane line and that he decided to stop the car for that reason. The court rejects as unsupported by any credible evidence the suggestion that Sgt. Kum-mer stopped the defendant in the absence of probable cause. Sgt. Rummer’s testimony that he observed a violation was not only credible; it was essentially uncontradicted.
Dist. Ct. Op. at 9.
. In several published and unpublished cases we have written that we review a district court’s denial of a motion to suppress under a clear error standard.
See, e.g., United States v. Vargas,
We trace the genesis of this language to our opinion in
United States v. Soto,
. See supra note 1.
. Because we find that Sergeant Rummer’s detection of the odor of marijuana emanating from the car at the inception of the stop established probable cause, we necessarily find that Sergeant Rummer’s continued questioning of Zabalza was proper. This finding, in turn, eliminates the need for this court to consider whether Zabalza’s consent was voluntary.
