Science Abuse Posted December 8, 2005 Report Share Posted December 8, 2005 I used a few along with my cars lap timer to figure my highway speed, since my speedometer is off. According to the measurments, 80mph on the speedo is about 100mph. I'd realy like to know how accurate they are, this is a big difference.

Mattsv8 Posted December 8, 2005 Report Share Posted December 8, 2005 very accurate. i use them to set my electronic speedo.the best ones are marked every `1/4 mile. theones with the 8th mile markes canget confusing because they tend to skip one.

SPLN SUX Posted December 8, 2005 Report Share Posted December 8, 2005 those little white dashes on the shoulder are exactly 1/4mile apart too... those are the ones cops get you with from the air. It should take you exactly 60 seconds to cross all 5 of them @ 60mph. Quote Link to comment Share on other sites More sharing options...

Total Sign Posted December 10, 2005 Report Share Posted December 10, 2005 Eric, I will bring my radar gun home tomorrow, you are more than welcome to use it, and it was a police issue, so it should be right on the money. Im also in Lewis Center, so it shouldnt be a far drive for you. Tommy Quote Link to comment Share on other sites More sharing options...
Kohones Posted December 10, 2005 Report Share Posted December 10, 2005 Agree the markers are accurate, I also (on boring drives over the years) have checked them, they're correct - Quote Link to comment Share on other sites More sharing options...

Tractor Posted December 11, 2005 Report Share Posted December 11, 2005 just use a GPS. Even a cheap one will be acurate to within 1 or 2 MPH. Evan Quote Link to comment Share on other sites More sharing options...
