The Massachusetts Driver's Manual contains some errors.
The RMV does not seem to care about fixing them.
Once a helpful person on the phone at the RMV encouraged me
to report errors and said they would be corrected. However,
the next time I called I got an attorney who angrily insisted
that nobody in a position of authority would have ever said
such a thing. He demanded to know who I had talked to,
presumably so he could discourage that person from ever
suggesting that the RMV might be wrong or responsive to
Although the manual says otherwise,
- A yellow advisory speed sign is not a speed limit sign and need
not be obeyed.
- Orange construction zone speed signs are also advisory, not regulatory.
- There is no minimum speed limit on limited access highways in
general. There is a 40 MPH minimum speed limit on the Massachusetts
Turnpike and a 20 MPH minimum speed limit in the harbor tunnels.
- An inactive signal is the same as no signal. One need not stop unless
traffic is approaching from the right.
- Vehicles do not need to yield to pedestrians crossing against
the signal. (However, all persons have a duty to use due care to
avoid a collision notwithstanding another's negligence.)
