It emerges from the present VLA 5-GHz total intensity and linear polarization observations of the BL Lac object 1400 + 162 that it has a misaligned triple structure with a prominent radio jet toward the east. Attention is given to possible explanations for the observed features of this source. While interaction with the cluster medium may be partly responsible for the observed distortion, it is suggested that the large misalignment may also be due to the amplification of a smaller misalignment by projection effects. In the context of the relativistic beaming model, where BL Lac objects arise when the relativistic jets are seen end-on, it is suggested that 1400 + 162 is more oblique to the line-of-sight than most members of its class.
