About us:
Wikispeedia is the most accurate speed limit database available for public use.
It was created in 2005 to collect and share the location of speed limits worldwide, helping people be aware of the speed limit.

Note: This app uses no cellular data, only Wifi. It is uniquely designed for civic groups who care about eliminating road rage, and improving traffic safety.

Usage: Enable GPS, drive around. Then Sync when you get home or such. Be safe, only sync when the car is off. The blue dots are places you should visit. The Green dots are old signs that you can claim. To claim them, drive down the side roads. When you are moving the same direction as a sign, it will show up. Otherwise it will be a dot. Put your email in Settings. At Wikispeedia, we share all contributions.

White Signs: Signs ahead of you.
Red corners: Direction you must travel to see the sign. E.g., N, S, E, W
Blue Dots: Signs that are not ahead of you. E.g., Nearby side road, reverse facing, etc.

Email us feature requests.

About us: There is no Federal or Private Speed limit database available for your use.
This is why Wikispeedia was formed, for you to be able to incorporate speed limit information in apps,
speedometers, cruise controls or safety apps. This is your database. Your signs are owned by you. Even if the speed limit changes, you found the sign and own it forever. Like adopt a road. If we have any money, it is distributed to donors, so please help out. All submissions are verified.

Tap the screen to suggest/correct a missing speed limit. We audit all submissions nightly. We pay contributors.

As you drive around, this app looks ahead and pulls in speed limits from wikispeedia.
They reside on your local SD card for future use.
