Regulatory Differences
Historically, one of the most conspicuous differences between UN and US regulations was the design and performance of headlamps. The Citroën DS shown here illustrates the large differences in headlamps during the 1940-1983 era when US regulations required sealed beam headlamps.
It is not currently possible to produce a single car design that fully meets both UN and US requirements simultaneously, but it is growing easier as both sets of regulations evolve. Given the size of the US vehicle market, and differing marketing strategies in North America vs. the rest of the world, many manufacturers produce vehicles in three versions: North American, rest-of-world right-hand drive (RHD) and rest-of-world left-hand-drive (LHD).

Famous quotes containing the word differences:
“The mother must teach her son how to respect and follow the rules. She must teach him how to compete successfully with the other boys. And she must teach him how to find a woman to take care of him and finish the job she began of training him how to live in a family. But no matter how good a job a woman does in teaching a boy how to be a man, he knows that she is not the real thing, and so he tends to exaggerate the differences between men and women that she embodies.”
—Frank Pittman (20th century)
