Variable speed limit signs to begin along I-95 in Virginia.

Starting Wednesday, the speed limit signs will be able to adjust the speed limit in real-time in an attempt to reduce congestion and keep travelers safer on the road.

1. Sounds like a great idea, but also another opportunity to run a speed trap scam. nt

2. So they can adjust the maximum speed limit to a point

that it’s 7 mph UNDER the current minimum speed limit on an interstate?

My car reads out the speed limit on both the heads up display and infotainment screen. But it’s based on current GPS data. It would now not only be useless, it could end up being expensive.

3. My car has that feature...I avoid using it. Street signs are old technology but work. nt

4. Street signs aren't always available.

5. I saw one on the way to work yesterday.

I go into DC on Wednesdays. The bus takes the EZPass lanes. Nearing the Pentagon, I saw a variable speed limit sign displaying 55 mph.
