The "Coastal Link Commuter Rail Service Act" establishes section 343.811 of chapter 343 of the Florida Statutes, which defines the roles and responsibilities of state and local agencies regarding indemnification and insurance obligations for commuter rail services operating on the Coastal Link corridor. The bill mandates that these agencies protect, defend, and indemnify rail operators, such as Brightline and Florida East Coast Railway (FECR), against liabilities arising from incidents involving passengers and invitees. It also sets conditions under which agencies can indemnify operators for liabilities exceeding a self-insurance retention amount of $5 million and ensures that liability is shared proportionately among operators in the event of accidents.

Additionally, the bill introduces provisions that require the responsible agency to assume a proportionate share of any loss or damage to rail corridor invitees and third parties, regardless of the agency's involvement. It caps liability for indemnification obligations at $323 million per occurrence, with adjustments based on allowable awards for claims from a single incident. The bill also requires the agency to purchase liability insurance and establish a self-insurance retention fund, while clarifying that these actions do not waive the agency's sovereign immunity. The act is set to take effect on July 1, 2025, and aims to facilitate the development and operation of commuter rail services while effectively managing associated risks and liabilities.
