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, due to increased reaction times and stopping distances or because fatigue is most prevalent in long distance lorry driving. 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 vehicl ...

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) or miles per hour (mph) or both. 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 mechanically propelled road vehicles 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 United Arab Emirates, 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 F ...

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] |
Slipstreaming
Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure and can even slightly reduce the energy expenditure of the lead vehicle. 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 that separates them from the swimmer they are abaft of thereby takin ...

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, where hypermilers can achieve up to in hybrid cars that have EPA ratings of 30 to 45 mpg (48 to 72 km/g). Hypermiling can be practiced in any vehicle regardless of fuel consumption. It gained popularity with 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, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Rage (phenomenon)
Road rage is aggressive or angry behavior exhibited by people driving a vehicle. 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. Behaviour has included (but is not limited to) cutting motorists off, inappropriate honking, flashing headlights, using obscene gestures, flipping off another driver, swerving, tailgating, brake checking, and physical confrontation. 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 each year throughout the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rear-end Collision
A rear-end collision, often called rear-ending or, in the UK, a shunt, occurs when a forward-moving vehicle crashes into the back of another vehicle (often stationary) in front of it. Similarly, rear-end classification of railway accidents, rail collisions occur when a train runs into the end of a preceding train on the same railway track, track. Common factors contributing to rear-end collisions include driver inattention or distraction, tailgating, panic stops, brake checking and reduced traction due to wet weather or road surface#Surface deterioration, worn pavement. According to the National Highway Safety Administration (NHTSA), rear-end collisions account for 7.5% of fatal automobile collisions. However, they account for 29% of all automobile accidents, making them one of the most frequent types of automobile accidents in the United States. According to NHTSA in 2020, out of 419,400 people involved in rear-end crashes, less than 1% were killed and over 99% were injured. ...

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] |
