How can you tell if a link acts like a roadblock?

Hi from sunny 19 deg C wetherby UK

I read somewhere some links cannont be passed thru if they use Javascript. With that in mind on this site  http://www.collegeofphlebology.com/ theres a horizontal scrolling nav bar illustrted here: http://i216.photobucket.com/albums/cc53/zymurgy_bucket/footer-nav-indexable.jpg

Ive got two questions please:

1. Are these links ok in that they do not represent an indexing roadblock
2. How can you tell if an internal link cannot be passed

Thanks in advance

just disable javascript and you can see how the search engines see it they are just using java to create the motion those links are seen and followed by google
