Common questions
Questions before you buy
What is the difference between a radar and laser detector?
A radar detector receives radio-frequency radar signals. A laser sensor detects light from lidar; its alert may occur only once a vehicle is being targeted.
Does a radar detector detect laser?
Some models include laser sensing, but it does not provide dependable advance warning because lidar beams are narrow and aimed at a specific vehicle.
Which is better, radar or laser detector?
They describe different sensing technologies, not interchangeable products. Many vehicle detectors receive radar and may also include a laser sensor; compare the exact feature list.
Can a detector stop a speeding ticket?
No detector guarantees a warning or prevents enforcement. Drive within posted limits and follow local laws.
