Why Is the Doppler Shift Zero When Both Vehicles Travel at the Same Speed?

[QUOTE="dwn, post: 4501893, member: 465592"] [h2]Homework Statement [/h2] A state trooper chases a speeder along a straight stretch of road; both vehicles move at 160 km/h. The siren on the trooper's vehicle produces sound at a frequency of 500 Hz. What is the Doppler shift in the frequency heard by the speeder? [h2]Homework Equations[/h2] This is what I need the answer to. [h2]The Attempt at a Solution[/h2] I understand why the answer is 500 Hz. They are both traveling at the velocity with respect to one another, so there is no doppler effect taking place---it is canceled out by the equal velocity and direction of the vehicles. What I do not understand is, how do I prove it? Thanks! [/QUOTE]
