Definite possibility. I think if you took it to court, there's a good chance that no one would show up.

I think this is a situation where it might be worth it to consult a lawyer, just to figure what your options are. All depending on how much of a fine you are facing, of course.

Yea my "friend" is weighing his options, but he said he will appeal it and hopefully get his 362 dollar ticket reduced. My friend is also interested in finding out if the radar is actually a video or just a tagged picture.

I know in WA state on some of the more open parts of I-90 (major highway) there are aircraft patrols which consist of light planes being flown overhead of the highway. They run what is essentially a dash cam like in a squad car, and use a combination of radar/laser within a certain range, and also the previously mentioned hash marks

hmmm interesting, what exactly is a hash mark though? As my friend was saying, its one thing if a cop gets you on the side of the road with a radar gun or you drive by them going to fast, but how accurate can a helicopter or airplane be? Thats what my friend is trying to figure out

ChrisSlicks · 07-11-2011, 09:26 AM

If they used the hash marks on the highway then they were using a stop watch and a lookup chart, not radar. There are air to ground radar systems but they are very expensive so not sure how prevalent they are outside of the military.

Either way, if you appeal you are entitled to discovery. File a motion with the court for the state's evidence, if they fail to produce the evidence then it is likely that your case will be dismissed. The evidence will allow you to do additional research into the potential accuracy of the speed measurement, and allow you to challenge on certain grounds.

Those lines going across the road on the highway... The airborne officers will time you from line one to line two, then divide that distance by your time, arriving at your average speed between two points. If the points are 1/2 mile apart and it takes you 24 seconds to go from line one to two, you're doing about 75 mph...

I'm sure if your "friend" seeks such information, they are obligated to give it to him. Tell him to let you know what they say so that you can inform us as well. I'm certainly interested to know.

they can get you for speeding in a variety of ways.

a friend of mine got a ticket because his average speed between two easy pass stations (a few miles apart) was to high. He made it to the next easy pass to quickly and the easy pass came up as a red flag and wouldnt let him through...cop walked over and told him to pull to the side of the road.

When aircraft are used in California, the spotter in the plane simply times you between painted marks that have set distances apart on the freeway. Once you are clocked they just call ahead to a waiting CHP.

Simple physics. Rate = distance/time

cajunz · 07-11-2011, 09:51 AM

No "air radar" used. Just timing the car between 1/4 mile hash marks on the road. I got nailed once in my '79 280zx by a state trooper helicopter. The trooper that pulled me over thought it was hilarious that my radar detector didn't warn me.

lawyer up, will be expensive now but will save you cash in the long run

PapoZalsa · 07-11-2011, 01:21 PM

That is why they have those white stripes painted across the highway. They can pin point your car and know how fast you are going from point A to point B. Then they will call the ground patrol if your are speeding according to their calculations.
