HI HB489

Creates a new offense of failure to yield right-of-way to a mass transit vehicle when the vehicle displays a yield sign and is entering a traffic lane after stopping to receive or discharge passengers.

Requires mass transit vehicles to display an illuminated, flashing yield sign on the back that warns drivers they must yield when the vehicle signals an intention to enter traffic.

Authorizes the Department of Transportation to adopt rules specifying the yield sign's message, size, shape, color, lettering, illumination, and placement on mass transit vehicles.

Violators are subject to a fine (amount unspecified in the bill) or community service, or both, and the law does not relieve mass transit drivers of their duty to drive safely.

Takes effect upon approval and does not affect rights, duties, or proceedings that occurred before the law's effective date.
