1. A computer comprising a processor and a memory storing instructions executable by the processor to:
identify a trailer behind a first vehicle;
upon identifying the trailer, generate a predesignated region behind the first vehicle, wherein the predesignated region is a region between the first vehicle and the trailer;
detect an object in data received from a rear-facing radar on the first vehicle;
activate an alarm in response to the object moving through the predesignated region at a speed below a threshold speed or for a duration above a threshold time; and
prevent the alarm from activating in response to the object being present in the predesignated region while detecting a second vehicle that is rearward from the trailer relative to the first vehicle and that is moving forward relative to the first vehicle.
