I would suggest that one point that's important to note here is that we're not necessarily talking about extensive periods past the hours of service limits. This is a small amount of time.
When it comes to flexibility, we look at the commercial vehicle drivers hours of service regulations. They already incorporate some flexibility around emergency situations, so this is not a fundamentally new approach; it's simply making sure that there is language specific to animal welfare considerations in the definition of emergency situations.
It therefore doesn't really fundamentally change how we approach the issue of flexibility; it just ensures that officers, when looking at their guidance and understanding what constitutes an emergency situation, also factor in those animal welfare considerations.
