Whats the point of having a portable radar flash your speed on a street?

Question

I don't really understand why Police departments use these devices at the tax payers expense. Every vehicle everywhere has a speedometer in the center of the dashboard. It's not like a driver does not know their speed or the speed limit. Actually I drive faster when I see one to watch it for fun. It would be different if it was for photo speed violations. DId I miss something here?

Answer 1

1. they work.

2. they stop speeders.

3. they stop speeders from killing themselves or someone else.

Answer 2

it is stupid but it does sorta make you consciously check your speed especially in an area like a school zone.  In my town they leave it up then a few days later there is a cop there, writing tickets like to shove it in your face.

Answer 3

I find them very useful .I use them to find out how accurate my speedometer is.And I think you will find out most people pay absolutely no attention to there speed.

Answer 4

Its used to alert drivers to how fast they are going. They are ususally used on roads that have reduced speed limits, or are common blackspots for crashes or speeding.

I find them pointless, because most of the time, they dont have the legal speedlimit shown on the screen.

There was 2 of these boards around a work area, which was reduced to 40km/h.

It was about 20km/h inaccurate, and most of the time, it didnt display your speed until after you had past the sign, so the next car saw your speed, slowed down, and created a bottle neck in traffic.

I went through the workzone in my car, which has just had its speedo calibrated, with cruise  control bang on 40km/h and the sign flashed up with 68km/h

I think they are a waste of time and money when used in that circumstance.

Answer 5

Yes. if you are speeding the post will take pic of liscense plate and send ticket.

Answer 6

They use radar boards because 90% of the driving public suffers from cranial rectal insertion and are completely oblivious to what's going on around them at any givin time.

The cops hope that a flashing speed will make thaem pull their head out and pay attention.
