I can hear it just fine when the radio is on.
I guess it would if it is tuned to the right frequency of the radar being used.
There is a thing call "audio rectification". There is a chance that a high powered transmitter can be heard on your car radio. This is due to the affect that the cable, usually speaker wires, act as an antenna and demod the transmitter. There were cases not to far from where I live that an AM broadcast transmitter was being heard on stereos that were turned off.
For a while when I had my pickup trucks I used to mod the stereo. When I would pass the Airport radar at the airport where I work, I could hear a buzz from the transmitter as I drove by.
Now this radar has a peak power several 1000's times a speed radar. It operates in the 2.7 - 2.9 GHz range.
So it is possible but I truly doubt it since I don't think the transmitter power from a speed radar is much above a couple hundred milliwatts.
This is the same as when I would transmit with my Ham Radio running 1000 watts on 18 MHz I would cause my air conditioner to go on and off during voice peaks. In 1 of my trucks I would get into the stereo while transmitting on 145 MHz. In both cases I put 'RF Chokes" on the Thermostat to solve the AC problem and the same "RF Chokes" on the speaker leads in my truck to stop the interference on the stereo.

i thought he ment a radar detector.. everyone that is new here seems to calls them "radars" Yes you may hear a radar signal in your radio if the radar was close enough to it and it was picking up a target. The target Doppler signal would be mixed down to a lower frequency for amplification and processing to a speed reading. I believe it would have to be right on the radio or radio antenna though.
