Are speed traps set up by police legal?


Speed traps set up by the police may or may not be legal depending on the jurisdiction you are driving in, the traffic laws and the type of speed trap that is being used. There are several different types of speed traps, but whether they are legal depends on the state or locality you live in:

  • The officer hiding his vehicle on a side road or behind the brush and checking the speed with radar
  • The officer timing the vehicle between two points and determining speed
  • A speed monitor on the side of the road with a camera which will take a picture of your vehicle and license; these speed monitors can even be inside of parked cars
  • Using a speed limit sign that is not easily seen or difficult to read

In some states, it is not legal for the officer to hide and be out of the sight of drivers. In addition, while the use of radar is legal, timing a vehicle is not an acceptable method. Most criticism comes from the method with the signs that are partially hidden or unclear. This is criticized as a real trap--one that should not be allowed, and in most places, one that is not legal.

In some states, speed traps are not legal except on local roads--California for one.  In Virginia, you do not get a speeding ticket per se; instead you are given a citation for reckless driving if you are using excessive speed. While a speeding ticket that came as a result of radar is the most common and is the most difficult to fight, some jurisdictions recognize only what is termed “road surveys”.
