Ships moving through the Strait follow a Traffic Separation Scheme (TSS), which separates inbound from outbound traffic to reduce the risk of collision. The traffic lane is six miles (10 km) wide, including two two-mile (3 km)-wide traffic lanes, one inbound and one outbound, separated by a two-mile (3 km) wide separation median.
To traverse the Strait, ships pass through the territorial waters of Iran and Oman under the "transit passage" provisions of the
United Nations Convention on the Law of the Sea. Although not all countries have ratified the convention,cite web |url=http://www.un.org/Depts/los/reference_files/chronological_lists_of_ratifications.htm |title=Chronological lists of ratifications of, accessions and successions to the Convention and the related Agreements as at 26 October 2007 |publisher=UN |work=Division for Ocean Affairs and the Law of the Sea] most countries, including the U.S., [citation|url=http://www.state.gov/documents/organization/58381.pdf|title=Presidential Proclamation 5030|author= U.S. President Ronald Reagan|date=March 10, 1983|accessdate=2008-01-21] accept these customary navigation rules as codified in the Convention.
The opening to the Persian Gulf was described, but not given a name, in the "
Periplus of the Erythraean Sea", a 1st-century mariner's guide:
:Ch.35. At the upper end of these Calaei islands is a range of mountains called Calon, and there follows not far beyond, the mouth of the Persian Gulf, where there is much diving for the pearl-mussel. To the left of the straits are great mountains called Asabon, and to the right there rises in full view another round and high mountain called Semiramis; between them the passage across the strait is about six hundred stadia; beyond which that very great and broad sea, the Persian Gulf, reaches far into the interior. At the upper end of this Gulf there is a market-town designated by law called Apologus, situated near Charaex Spasini and the River Euphrates.
There are two opinions about the etymology of this name. In popular belief the derivation is from the name of the Persian God هرمز "Hormoz" (a variant of "
Ahura Mazda"). Compare the Pillars of Herculesat the entrance to the Mediterranean. Scholars, historians and linguists derive the name "Ormuz" from the local Persian word هورمغ "Hur-mogh" meaning datepalm. In the local dialects of Hurmoz and Minab this strait is still called Hurmogh and has the aforementioned meaning.
Operation Praying Mantis
18 April 1988, the U.S. Navy waged a one-day battle against Iranian forces in and around the strait. The battle, dubbed Operation Praying Mantisby the U.S. side, was launched in retaliation for the 14 Aprilmining of the USS "Samuel B. Roberts" (FFG-58). U.S. forces sank two Iranian warships, Joshanand as many as six armed speedboats in the engagement.
The downing of Iran Air 655
July 3, 1988, 290 people were killed when an Iran Air Airbus A300passenger jet was shot down over the strait by the United States Navy guided missile cruiserUSS "Vincennes". There is still lingering controversy about the event, considered among the most controversial tragedies in aviationhistory.
Collision between USS "Newport News" and tanker "Mogamigawa"
January 10, 2007, the nuclear submarine USS "Newport News", traveling submerged, struck M/V "Mogamigawa", a 300,000-ton Japanese-flagged very large crude tanker, south of the strait.

2008 US-Iranian naval dispute
A series of naval stand-offs between Iranian speedboats and US warships in the Strait of Hormuz occurred in December 2007 and January 2008. US officials accused Iran of harassing and provoking their naval vessels; Iranian officials denied these allegations. On
January 14 2008, US naval officials appeared to contradict the Pentagon version of the Jan. 16 event, in which U.S. officials said U.S. vessels were near to firing on approaching Iranian boats. The Navy's regional commander, Vice Admiral Kevin Cosgriff, said the Iranians had "neither anti-ship missiles nor torpedoes" and that he "wouldn't characterize the posture of the US 5th Fleet as afraid of these small boats".

2008 Iranian Threats
On June 29, 2008, the commander of
Iran's Revolutionary Guard, Ali Mohammed Jafari, stated that if Iran were attacked by Israel or the United States, it would seal off the Strait of Hormuz, thereby wreaking havoc in oil markets. This statement followed other more ambiguous threats from Iran's oil minister and other government officials that a Western attack on Iran would result in oil supply turmoil.
In response, Vice Admiral Kevin Cosgriff, commander of the U.S. 5th Fleet stationed in Bahrain across the Persian Gulf from Iran, warned that such an action by Iran would be considered an act of war, and that the U.S. would not allow Iran to effectively hold hostage nearly a third of the world's oil supply.

On July 8, 2008, Ali Shirazi, a mid-level clerical aide to Iran's Supreme Leader
Ayatollah Ali Khamenei, was quoted by the student news agency ISNAas saying to Revolutionary Guards, "The Zionist regime is pressuring White House officials to attack Iran. If they commit such a stupidity, Tel Aviv and U.S. shipping in the Persian Gulf will be Iran's first targets and they will be burned."

One analyst concluded that Iran could seal off or impede traffic in the Strait for a month, and a U.S. attempt to reopen it would likely escalate the conflict.

2008 Naval Activity
In the last week of July 2008, Operation Brimstone [cite web |url=http://www.navy.mil/search/display.asp?story_id=38478|title = JTFEX 08-4 "Operation Brimstone" Flexes Allied Force Training|publisher=US Navy|date=

As of August 11, 2008, more than 40 US and allied ships are reported en route to the Straits of Hormuz. One US carrier battle group from Japan will complement two more which are already in the Gulf, for a total of five battle groups, not counting submarines.
