No more speed traps, no more problems. (baahahahah Sécurité routière... . Keep collecting and getting run over for all I care, corrupted mafia tax&collect police)
Let's do like California:
40801:
No peace officer or other person shall use a speed trap in arresting, or participating or assisting in the arrest of, any person for any alleged violation of this code nor shall any speed trap be used in securing evidence as to the speed of any vehicle for the purpose of an arrest or prosecution under this code.
40802 A "speed trap" is either of the following:
(a) A particular section of a highway measured as to distance and with boundaries marked, designated, or otherwise determined in order that the speed of a vehicle may be calculated by securing the time it takes the vehicle to travel the known distance.
This means that "airplane surveillance" tickets are illegal in California, unless the arresting officer paces your vehicle to determine your speed. I received two such tickets (in 1990 and 1992) and contested them. In both cases it was not necessary for me to say anything -- the judge asked the arresting officer if this case was related to airplane surveillance, and the charges were dismissed "in the interest of justice."
Section 40802(b):
defines where "radar or other electronic devices" can be used to determine speed -- in essence, either on "local streets and roads" or on highways where a traffic survey has been conducted within the last five years. I find that California police are very familiar with this law, and with the local traffic surveys.
