Aren't radar detector devices the best way to avoid speed traps and radar guns?

Radar detector devices alert the driver to police radar and to speed guns, allowing the driver to slow down before he or she is detected exceeding the speed limit. A few states have declared radar detectors illegal for all vehicles, but in general the laws single out "commercial" vehicles over ten thousand pounds (i.e., trucks). Some states use radar detector detectors to stop drivers who have radar detectors installed.
