Restart Study
The FMCSA is doing a study of the 34 hour restart. As you know, it was added to log book regulations, then modified, then un-modified. They are still trying to get it right.
The following was taken from the FMCSA Facebook page. If you are a driver, it might be worth your while to take a look:
