Tailgating
Tailgating is the action of a driver driving behind another vehicle while not leaving sufficient distance to stop without causing a collision if the vehicle in front stops suddenly. The safe distance for following another vehicle varies depending on various factors including vehicle speed, weather, visibility and other road conditions. Some jurisdictions may require a minimal gap of a specified distance or time interval. When following heavy vehicles or in less than ideal conditions (e.g. low light or rain), a longer distance is recommended. Causes There can be several reasons for tailgating. Preventing cut ins Tailgating can occur when a vehicle attempts to prevent another vehicle on the right or left from cutting in front of them. The tailgating (or preventing) vehicle will drive as close as possible to another leading vehicle to prevent the side vehicle from cutting in. Like all forms, this practice of tailgating is illegal and attempts to force the side vehicle to slow dow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Speed Limit
Speed limits on road traffic, as used in most countries, set the legal maximum speed at which vehicles may travel on a given stretch of road. Speed limits are generally indicated on a traffic sign reflecting the maximum permitted speed - expressed as kilometres per hour (km/h) and/or miles per hour (mph). Speed limits are commonly set by the legislative bodies of national or provincial governments and enforced by national or regional police and judicial authorities. Speed limits may also be variable, or in some places nonexistent, such as on most of the Autobahnen in Germany. The first numeric speed limit for automobiles was the limit introduced in the United Kingdom in 1861. the highest posted speed limit in the world is , applied on two motorways in the UAE. Speed limits and safety distance are poorly enforced in the UAE, specifically on the Abu Dhabi to Dubai motorway - which results in dangerous traffic, according to a French-government travel-advisory.

Slipstreaming
Drafting or slipstreaming is an aerodynamic technique where two vehicles or other moving objects are caused to align in a close group, reducing the overall effect of drag due to exploiting the lead object's slipstream. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure required to maintain a certain speed and can also slightly reduce the energy expenditure of the lead vehicle or object. Drafting in sport Drafting is used to reduce wind resistance and is seen most commonly in bicycle racing, motorcycle racing, car racing, and speedskating, though drafting is occasionally used even in cross-country skiing, downhill skateboarding, and running. Some forms of triathlon allow drafting. Drafting occurs in swimming as well: both in open-water races (occurring in natural bodies of water) and in traditional races in competition pools. In a competition pool a swimmer may hug the lane line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two Second Rule
The two-second rule is a rule of thumb by which a driver may maintain a safe trailing distance at any speed. The rule is that a driver should ideally stay at least two seconds behind any vehicle that is directly in front of his or her vehicle. It is intended for automobiles, although its general principle applies to other types of vehicles. Some areas recommend a three-second rule instead of a two-second rule to give an additional buffer. The rule is not a guide to safe ''stopping'' distance, it is more a guide to reaction times. The two-second rule tells a defensive driver the ''minimum'' distance needed to reduce the risk of collision under ideal driving conditions. The allotted two-seconds is a safety buffer, to allow the following driver time to respond. The practice has been shown to considerably reduce the risk of collision and also the severity of any injuries if a collision occurs. It also helps to avoid tailgating and road rage for all drivers. A large risk of tailga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rear-end Collision
A rear-end collision (often called simply rear-end or in the UK a shunt) occurs when a vehicle crashes into the one in front of it. Common factors contributing to rear-end collisions include driver inattention or distraction, tailgating, panic stops, and reduced traction due to wet weather or worn pavement. Rear-end rail collisions occur when a train runs into the end of a preceding train. According to the National Highway Safety Administration (NHTSA), rear-end collisions account for only 6% of fatal automobile crashes. However, they account for 28% of all automobile accidents, making them one of the most frequent types of automobile accidents in the United States. Overview Typical scenarios for rear-ends are a sudden deceleration by the first car (for example, to avoid someone crossing the street) so that the driver behind it does not have time to brake and collides with it. Alternatively, the following car may accelerate more rapidly than the leading one (for example, lea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Rage (phenomenon)
Road rage is aggressive or angry behavior exhibited by motorists. These behaviors include rude and verbal insults, yelling, physical threats or dangerous driving methods targeted at other drivers, pedestrians or cyclists in an effort to intimidate or release frustration. Road rage can lead to altercations, damage to property, assaults, and collisions that result in serious physical injuries or even death. Strategies include (but are not limited to) cutting motorists off, inappropriate honking, flipping off another driver, swerving, tailgating, brake checking and attempting to fight. According to a study by the AAA Foundation for Traffic Safety that examined police records nationally, there were more than 1,250 incidents of road rage on average reported per year between 19901996 in the United States. Many of these incidents have ended with serious injuries or fatalities. These rates rose yearly throughout the six years of the study. A number of studies have found that individuals ...

Assured Clear Distance Ahead
In legal terminology, the assured clear distance ahead (ACDA) is the distance ahead of any terrestrial locomotive device such as a land vehicle, typically an automobile, or watercraft, within which they should be able to bring the device to a halt. It is one of the most fundamental principles governing ordinary care and the duty of care for all methods of conveyance, and is frequently used to determine if a driver is in proper control and is a nearly universally implicit consideration in vehicular accident liability. The rule is a precautionary trivial burden required to avert the great probable gravity of precious life loss and momentous damage. Satisfying the ACDA rule is necessary but not sufficient to comply with the more generalized basic speed law, and accordingly, it may be used as both a layman's criterion and judicial test for courts to use in determining if a particular speed is negligent, but not to prove it is safe. As a spatial standard of care, it also serves as r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypermiling
Hypermiling is driving or flying a vehicle with techniques that maximize fuel efficiency. Those who use these techniques are called "hypermilers". In the case of cars, this is an extreme form of energy-efficient driving. Hypermiling can be practiced in any vehicle regardless of fuel consumption. It gained popularity due to the rise in gasoline prices in the 2000s. Some hypermiling techniques are illegal in some countries because they are dangerous. In 2008, the ''New Oxford American Dictionary'' voted "hypermiling" the best new word of the year. Safety and awareness program Hypermiling has come under fire from several sides because some hypermilers show dangerous or illegal behaviour, such as tailgating larger vehicles on motorways to save fuel, cycling between accelerating and coasting in neutral, and even turning the engine off when its power is not needed. For this reason, the Hypermiling Safety Foundation was established in August 2008 to promote a safety and education program ...

Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center of trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maryland
Maryland ( ) is a state in the Mid-Atlantic region of the United States. It shares borders with Virginia, West Virginia, and the District of Columbia to its south and west; Pennsylvania to its north; and Delaware and the Atlantic Ocean to its east. Baltimore is the largest city in the state, and the capital is Annapolis. Among its occasional nicknames are '' Old Line State'', the ''Free State'', and the '' Chesapeake Bay State''. It is named after Henrietta Maria, the French-born queen of England, Scotland, and Ireland, who was known then in England as Mary. Before its coastline was explored by Europeans in the 16th century, Maryland was inhabited by several groups of Native Americans – mostly by Algonquian peoples and, to a lesser degree, Iroquoian and Siouan. As one of the original Thirteen Colonies of England, Maryland was founded by George Calvert, 1st Baron Baltimore, a Catholic convert"George Calvert and Cecilius Calvert, Barons Baltimore" William Hand Browne, ...
