Understanding the Pre-existing Modified Supplementary Safety Measure

Definition & Meaning

A pre-existing modified supplementary safety measure (Pre-existing Modified SSM) refers to a safety system or procedure related to highway-rail grade crossings. Specifically, it is a system that was installed before December 18, 2003, by the relevant traffic control or law enforcement authority. While it is listed in appendix A of the regulations, it does not fully comply with the established safety standards. This term is important for understanding the safety protocols in place at these crossings, particularly those that may not meet current regulations but were operational prior to the cutoff date.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A city has a railroad crossing equipped with lights and gates that were installed in 2002. While these systems provide some safety measures, they do not meet the latest federal standards. This crossing would be classified as having a pre-existing modified SSM.

Example 2: A rural area utilizes a warning sign system for a grade crossing that was set up in 2001. Although it is recognized as a safety measure, it lacks the updated technology required by current regulations, qualifying it as a pre-existing modified SSM.

State-by-state differences

Examples of state differences (not exhaustive):

State Variation
California Strict enforcement of updated safety measures at all crossings.
Texas Allows for certain pre-existing measures to remain in use if deemed safe.
Florida Regular reviews of safety measures, with potential upgrades mandated.

This is not a complete list. State laws vary, and users should consult local rules for specific guidance.
