An arterial road, or arterial thoroughfare, is a high-capacity urban road. The primary function of an arterial road is to deliver traffic from collector roads to freeways, and between urban centres at the highest level of service possible. As such, many arteries are limited-access roads, or feature restrictions on private access. Though the design of arterial roads varies from country to country, city to city, and even within those cities, they share a number of common design characteristics. In many cities, arteries are arranged in concentric circles (commonly referred to as a ring road) or in a grid. Many jurisdictions also classify arterial roads as either principal (major) or minor.

In traffic engineering hierarchy, an arterial road delivers traffic between collector roads and freeways. For new arterial roads, intersections are often reduced to increase traffic flow. In California, arterial roads are usually spaced every half mile, and have intersecting collector(s) and streets. Some arterial roads, if having a small fraction of intersections and driveways compared to most arterial roads, are also considered to be expressways in some countries and some states of the United States.

Ray White is a soul vocalist and rock and blues guitarist, best known as a member of Frank Zappa's touring ensembles. He was drafted into Zappa's band in the fall of 1976, being featured on rhythm guitar and vocals, forming a memorable vocal harmony partnership with Ike Willis on later tours in 1980 and 1984. White's vocals can be heard on Zappa in New York (March 1978), You Are What You Is (Sept 1981) as well as others. White can also be found on a The Torture Never Stops and Does Humor Belong in Music?; the former a DVD set in one of Zappa's last tours (without Ike Willis) and the latter being a VHS filmed at the pier in New York, the video features White and Ike Willis' signature vocal harmonies. According to Zappa, White, who was deeply religious, was uncomfortable with the atheistic views of some of the other band members, which led to his departure.

White has also worked with jam-oriented groups like KVHW, Don't Push the Clown and Umphrey's McGee since his contributions to the Zappa band, and has more recently worked with a variety of Michigan artists, including former Rare Earth drummer Bob Weaver, as well as members of the funk/fusion combo Generic Produce.
