RDD Radar Detectors: Understanding Detector-Detector Alerts

An RDD, or radar detector detector, looks for emissions from some radar detectors. Compare documented features and local rules.

An RDD radar detector is a radar detector detector: equipment used to identify emissions from some radar detectors. That differs from detecting police radar itself. Understand what a detector may emit, which RDDs are relevant and whether using a detector is lawful where you drive.

Common questions

Questions before you buy

What does RDD stand for on a radar detector?

RDD means radar detector detector: equipment intended to detect emissions from radar detectors.

Can police detect every radar detector?

No. Results depend on detector design, RDD capability, distance and conditions.

Are radar detectors with VG-2 protection undetectable?

VG-2 resistance concerns a specific system, not every possible RDD. Check model documentation and local law.

Do radar detector detectors detect police radar?

No. An RDD looks for detector emissions; a radar detector looks for speed-enforcement signals.
