However, other commonly used terms describing highway signs that can display different messages are found within National and New York State publication and policy ***uments. Examples of these terms are as follows:
&©|8226; ¡°VMS¡± (Variable Message Sign) shall mean a device to display a variety of text messages to motorists traveling the Thruway. It is a traffic control device that typically suggests motorists alter their driving in some manner and take appropriate actions. A VMS is not typically used as a regulatory sign as recognized within the MUTCD.
&©|8226; ¡°CMS¡± (Changeable Message Sign) shall mean a non-static sign that supports a limited number of fixed messages. An example would be the rotating drum sign used in E-ZPass operations. This term is currently contained in the 2003 edition of the Federal MUTCD.
