  ZrTe$_5$ has been of recent interest as a potential Dirac/Weyl semimetal
material. Here, we report the results of experiments performed via in-situ 3D
double-axis rotation to extract the full $4\pi$ solid angular dependence of the
transport properties. A clear anomalous Hall effect (AHE) was detected for
every sample, with no magnetic ordering observed in the system to the
experimental sensitivity of torque magnetometry. Interestingly, the AHE takes
large values when the magnetic field is rotated in-plane, with the values
vanishing above $\sim 60$ K where the negative longitudinal magnetoresistance
(LMR) also disappears. This suggests a close relation in their origins, which
we attribute to Berry curvature generated by the Weyl nodes.
