Between ames and dm 80 ( there really is no place for an officer to turn around, just slow down at on ramps)
between ames and hwy 20 75
I80 to IC typically 75-78 but its easy to find a pack and jump in and go 80
I235 between Ankeny/WdM 5-8 over never more than 10 bc of cameras


Always within 5 mph over in commercial vehicles for work.

Found this one out the hard way in September :/.
Usually 7-10 over. Except the tollways in the Chicago suburbs, 80 in a 55 is just staying with traffic.

All of this in terms of rural driving:
2 lane highways:8-10 mph over(assuming the road is relatively flat and straight)
4 lane divided: 5-8 over
Interstate: 5 mph over

I drive what I feel comfortable with driving.

Night time maybe 5-10mph over
On a clear interstate, during the day, and the weather is good 15-20mph over.
Bad weather=Slower then about anyone else

On 235 at 5am when I go to work I normally drive around 75 (60mph limit) until I get to the speed cameras then I drive 68 for an 1/8th of a mile.

I also find myself driving a little bit slower now that I have a pickup compared to when I had a luxury sedan. If you think about it, it seems pretty ridiculous that a 1973 Surburban can drive the same speed limit as a 2013 Mercedes S class.

I usually go between 8-10 over on the interstate, and 5-7 everywhere else. Of course, I live in Cedar Rapids, so the three lanes of 380 is left lane-5 over, middle lane-speed limit, right lane-5 under. The worst drivers in the state live here.

100% correct

If I'm using cruise control I set it at about 3 mph over. If not I am usually about 10 over.

Or if I am on the motorcycle in western Nebraska or Wyoming. I look down and see myself creeping up towards 90- 100 and have to back off, only to start creeping up again.

I'm quite happy that they upped the speed limit to 70mph here recently, as I don't feel the need to go much over that while driving anyway. I usually set the cruise to 73mph and let it ride. It's a comfortable speed, and anything much more than that and you're just destroying your fuel mileage.

Usually 6-8 over on the interstate. *Knock on wood*, I haven't been pulled over for speeding in 15 years.

If you're going to slow down at every on ramp, is it really worth it?

Anyone ever been caught by a plane? I was with a buddy once who always bragged about his $400 radar detector. Then he got pulled over while going ~15 over, cop even gave him **** about his fancy dancy detector :biglaugh:

Radar detector? What, is it 2004?

I've heard a cop or 2 claim they usually go by "8 you're great, 9 you're mine"...


So I stick around 7 over usually.

My brother used to handle the car electronics for the Iowa State patrol. He asked the troopers at what point do they stop speeders. They told him they'll let you go seven, but stop you at eight. Unless they see a radar detector - then they stop at three.

I pay more attention to RPM's then I do speed. In 55 MPH, I usually go about 6 over, which is 2,000 RPM's on my car. On Highways/Interstates wheres the limit is 65 or 70, I'm always at about 74, which is 2,500 RPM's on my car. For me, anytime I get over 2,500 RPM's, my gas mileage starts to decrease pretty fast, and anytime I can keep it at about 2,000, my gas mileage goes up quite a bit.

Four or five over, but I'm a stickler for being on time so I'm generally not running late or in a hurry. I go a little over the limit just to stay with the overall traffic flow.

And I apologize for going a little off topic, but it drives me nuts on I-235 between 42nd and 63rd when everyone realizes that there are speed cameras set up so instead of dropping to the speed limit or just a little over everyone drops below the speed limit.

My Valentine One has paid me back 10x. Hardwired next to my mirror so unless you're standing next to my car, you don't see it.
