Walter Darnell Hughes appeals his guilty-plea conviction and sentence for two counts of transporting undocumented aliens within the United States by means of a motor vehicle for private financial gain. Hughes argues that the facts of this case do not give rise to the level of endangerment required for a sentencing enhancement under U.S.S.G. § 2Ll.l(b)(5).

The presentence report stated that ten undocumented aliens were found within the sleeper compartment of Hughes’s tractor-trailer with regard to the first count and four undocumented aliens were found with regard to the second count. Ten aliens concealed in storage compartments in a sleeper area of a tractor-trailer constitutes harboring persons in a crowded and dangerous condition. § 2Ll.l(b)(5), comment. (n.6).

Some of the aliens gave material witness statements to the effect that Hughes instructed them to hide in various compart *435 ments within the sleeper area of his tractor-trailer. The aliens were hidden in closets, under beds, and various other storage compartments. One alien detailed how he was instructed by Hughes to hide with another alien in a closed compartment underneath the bed. The aliens were required to crouch in a fetal position in order to fit in the compartment. This position, maintained in a closed compartment, would make it difficult for the aliens to extricate themselves. See United States v. Rodriguez-Mesa, 443 F.3d 397, 403 (5th Cir. 2006). The district court’s application of the enhancement was not error. Id.

Accordingly, the district court’s judgment is AFFIRMED.
