The bill mandates the commissioner of transportation to amend existing rules regarding the use of railroad crossing bells. Specifically, by July 1, 2027, the rules will require that bells be silenced when the front of a train reaches the crossing or when the gate arm is nearly horizontal, except in cases where the crossing is within 1,000 feet of residential property. This change aims to reduce noise pollution in residential areas near railroad crossings.

Additionally, the bill allows the commissioner to utilize a good cause exemption to adopt these rules, indicating flexibility in the rulemaking process. The provisions of this section will take effect the day after the bill is enacted, ensuring a prompt implementation of the new regulations.
