RDD Radar Detectors: Understanding RDD Immunity Claims

RDD means radar detector detector: equipment intended to identify emissions from radar detectors. It is separate from police radar.

It is marketed as reducing detection by certain RDD equipment. The phrase is not a guarantee against every device or condition.

Some manufacturers make reduced-RDD-detectability claims for specific models. Verify the exact model’s current documentation; do not treat the claim as universal.

No. Provincial law applies regardless of stealth or RDD claims. Detectors are permitted only in British Columbia, Alberta and Saskatchewan, with a commercial-vehicle restriction in Saskatchewan.
