OG-116 - trouble in understanding the sentence

Can someone helps me explain this highlighted sentence in OG116? I read it several times but still don't understand the meaning... Thank you!!

Laws requiring the use of headlights during daylight hours can prevent automobile collisions. However, since daylight visibility is worse in countries farther from the equator, any such laws would obviously be more effective in preventing collisions in those countries. In fact, the only countries that actually have such laws are farther from the equator than is the continental United States

In fact, the only countries that actually have such laws are farther from the equator than is the continental LACE>United StatesLACE>

LACE>实际上，仅有的有这个法律的国家都比美国本土更加远离赤道。LACE>

i see... is the right order of the sentence like this?

In fact, the only countries [that actually have such laws] are father from the equator than the continental United States is (from the equator).

mm说的没错。
