Oklahoma rest stops with green designated areas?

No clue, but they have it in Wisconsin also at at least 1 rest area I can think of. Just figured it was something new they were testimg on the pavement.

 

Iowa has them also in a couple rest areas between Des Moines and Iowa City. Supposed to be sensors for open parking spaces. If you drive on 35 north in Minnesota. There is a rest area just before Minneapolis that has a sighn that says how many open spaces there are. I believe its supposed to end up being something similar. I know they are the last spots parked on.

New technology launching at Iowa rest stops for truck drivers

 

Here is a quote from the article @Hawkeye72 linked above.

Nearly 90 percent of all crashes involving truck drivers are because of fatigue.

Not even close.

And putting in an expensive sensor system that is broken 6 months later is useless to any driver.
Oh look, it says there are 31 spaces available at a rest area 120 miles away. You get there and lo and behold, all full with 25 trucks on the exit and entrance ramp.

 

A no idle area?

 

Only green painted Volvo VNX 300 trucks can park on green pavement
