speed trap work like sonar.the only way to bypass is stealth technology like f-22 or radar jamming device.radar detector won't help much as once u already detected the speed-trap signal the system n a summon is otw to ur doorstep. satellite data transfer rate in this area is high.like in garmin or other devices is only mark the area as speed-trap area to ask u slow down.
Bro, the radar detector is not to jam or even 'safe' you from the speed trap. It will pre-notify you that there will be a speed trap in front, where you'll slow down to proper limit before you reach the 'trap' zone. It works many time for me, no problem.
