  Testing autonomous vehicles (AVs) requires complex oracles to determine if
the AVs behavior conforms with specifications and humans' expectations.
Available open source oracles are tightly embedded in the AV simulation
software and are developed and implemented in an ad hoc way. We propose a
domain specific language that enables defining oracles independent of the AV
solutions and the simulator. A testing analyst can encode safety, liveness,
timeliness and temporal properties in our language. To show the expressiveness
of our language we implement three different types of available oracles. We
find that the same AV solutions may be ranked significantly differently across
existing oracles, thus existing oracles do not evaluate AVs in a consistent
manner.
