Seeing I have only rejoined the WA recently, forgive me for being a tad confused here ...
"Applauding the target resolution's intentions of setting standards for roads, bridges, and tunnels used for international travel to increase safety on public highways connected in more than one nation;"
What resolution are we repealing again?
The ITSC only makes regulations for such things "at points where roads cross international borders at which one or more member states operate customs, immigration, or other border checkpoints." It makes recommendations for all other occasions of highway infrastructure.
The basic thrust of the resolution is "international commercial road vehicles."
Clearly there is a major disconnect between what the resolution does and what the repeal thinks it does. It does not place undue burden on a nation's infrastructure, except possibly at crossing points.
Moreover since this resolution has been in place for a very long time we can assume that the committee has not done the things you have suggested it does because it would have been repealed ages ago.
Therefore, we are opposed to this repeal.
