There are a few ways you can detect a speed trap and avoid or prepare for them.
1. Trapster is a mobile app where users share real time information. See Trapster.com
2. Use a Radar Detector. (If your state allows them).
3. Watch other drivers – if they are slowing down for no apparent reason, there may be a speed trap ahead.
4. Be aware of speed limit changes. Cops often wait for drivers that fail to recognize speed limit changes, especially when a road expands to more lanes yet the limit decreases.
5. Use caution on national holidays and around major events – where people gather, so do police.
6. School zones are the number one hot spot for speed traps.
7. Take note where you see a speed trap, odds are it will reappear often.
8. If another driver flashes their headlights at you, it may be a courteous way of saying there is a cop fishing for speeders ahead. Raise your awareness.
9. Be aware when coming around sharp turns or cresting on a hill, when you can’t see the road ahead. Cops know you can’t see them by the time they radar you.
10. When going from a rural road into town or to a populated area, always watch for speed traps.
