Why extend the 14 to 16 and leave the 10 hour rule in place? that confuses things even more.
The only two things they need to change is;
allowing the driver to stop the clock not with 5 and 5 but in two hour increments followed by a 10 hour reset - not 8 hours. This will allow teams the flexibility but also solos too.
The other is to revise the Electronic Logging regs, they are open for interpretation and don't follow the mandate from the congress about electronic signatures for interstate commerce.
