Driving Techniques
Driving is the controlled operation and movement of a land vehicle, including cars, motorcycles, trucks, and buses. A driver's permission to drive on public highways is granted based on a set of conditions being met, and drivers are required to follow the established road and traffic laws in the location they are driving. The word "driving" has etymology dating back to the 15th century. Its meaning has changed from primarily driving working animals in the 15th century to automobiles in the 1800s. Driving skills have also developed since the 15th century, with physical, mental and safety skills being required to drive. This evolution of the skills required to drive have been accompanied by the introduction of driving laws which relate not only to the driver but also to the driveability of a car. The term "driver" originated in the 15th century, referring to the occupation of driving working animals such as pack or draft horses. It later applied to electric railway drivers in ...

Convertible Mercedes Car Driving On A Highway
A convertible or cabriolet () is a Car, passenger car that can be driven with or without a roof in place. The methods of retracting and storing the roof vary across eras and manufacturers. A convertible car's design allows an open-air driving experience, with the ability to provide a roof when required. A potential drawback of convertibles is their reduced Torsion (mechanics), structural rigidity (requiring significant engineering and modification to counteract the side effects of almost completely removing a car's roof). The majority of convertible roofs are of a folding construction framework with the actual top made from cloth or other fabric. Other types of convertible roofs include retractable hardtops (often constructed from metal or plastic) and Convertible#Detachable hardtop, detachable hardtops (where a metal or plastic roof is manually removed and often stored in the trunk (car), trunk). Terminology Other terms for convertibles include cabriolet, cabrio, drop top, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle Dynamics
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics. It may be applied for motorized vehicles (such as automobiles), bicycles and motorcycles, aircraft, and watercraft. Factors affecting vehicle dynamics The aspects of a vehicle's design which affect the dynamics can be grouped into drivetrain and braking, suspension and steering, distribution of mass, aerodynamics and tires. Drivetrain and braking * Automobile layout (i.e. location of engine and driven wheels) * Powertrain * Braking system Suspension and steering Some attributes relate to the geometry of the suspension, steering and chassis. These include: * Ackermann steering geometry * Axle track * Camber angle * Caster angle * Ride height * Roll center * Scrub radius * Stee ...

Century Dictionary
''The Century Dictionary and Cyclopedia'' is one of the largest encyclopedic dictionaries of the English language. It was compared favorably with the ''Oxford English Dictionary,'' and frequently consulted for more factual information than would normally be the case for a dictionary. History The ''Century Dictionary'' is based on '' The Imperial Dictionary of the English Language'', edited by Rev. John Ogilvie (1797–1867) and published by W. G. Blackie and Co. of Scotland, 1847–1850, which in turn is an expansion of the 1841 second edition of Noah Webster's ''American Dictionary''. In 1882 The Century Company of New York bought the American rights to ''The Imperial Dictionary'' from Blackie and Son. The first edition of the ''Century Dictionary'' was published from 1889 to 1891 by The Century Company, and was described as "six volumes in twenty four". The first edition runs to 7,046 pages and features some 10,000 wood-engraved illustrations. It was edited by Sanskrit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Packhorse
A packhorse, pack horse, or sumpter refers to a horse, mule, donkey, or pony used to carry goods on its back, usually in sidebags or panniers. Typically packhorses are used to cross difficult terrain, where the absence of roads prevents the use of wheeled vehicles. Use of packhorses dates from the Neolithic period to the present day. Today, westernized nations primarily use packhorses for recreational pursuits, but they are still an important part of everyday transportation of goods throughout much of the developing world and have some military uses in rugged regions. History Packhorses have been used since the earliest period of domestication of the horse. They were invaluable throughout antiquity, through the Horses in the Middle Ages, Middle Ages, and into modern times where roads are nonexistent or poorly maintained. Historic use in England Packhorses were heavily used to transport goods and minerals in England from medieval times until the construction of the first toll ro ...

Working Animal
A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons, and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or leather. The history of working animals may predate agriculture as dogs were used by hunter-gatherer ancestors; around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins and some Asian elephants. People have found uses for a wide variety of abili ...

World Health Organization
The World Health Organization (WHO) is a list of specialized agencies of the United Nations, specialized agency of the United Nations which coordinates responses to international public health issues and emergencies. It is headquartered in Geneva, Switzerland, and has 6 regional offices and 150 field offices worldwide. Only sovereign states are eligible to join, and it is the largest intergovernmental health organization at the international level. The WHO's purpose is to achieve the highest possible level of health for all the world's people, defining health as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." The main functions of the World Health Organization include promoting the control of epidemic and endemic diseases; providing and improving the teaching and training in public health, the medical treatment of disease, and related matters; and promoting the establishment of international standards for biologic ...

Vehicle Registration
Motor vehicle registration is the registration of a motor vehicle with a government authority, either compulsory or otherwise. The purpose of motor vehicle registration is to establish a link between a vehicle and an owner or user of the vehicle. While almost all motor vehicles are uniquely identified by a vehicle identification number, only registered vehicles display a vehicle registration plate and carry a vehicle registration certificate. Motor vehicle registration is different from motor vehicle licensing and roadworthiness certification. Motor vehicles may also be registered with property owners or managers to gain benefits. For example, organisations with parking facilities may require registration of a vehicle with them to allow authorised users to park there. Australia In Australia, all motor vehicles are required to be registered before being driven on public roads. Registration can be with one of the registration authorities set up by each state or territory. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driver Licensing
A driver's license, driving licence, or driving permit is a legal authorization, or the official document confirming such an authorization, for a specific individual to operate one or more types of motorized vehicles—such as motorcycles, cars, trucks, or buses—on a public road. Such licenses are often plastic and the ISO/IEC 7810#ID-1, size of a credit card. In most international agreements, the wording "driving permit" is used, for instance in the Vienna Convention on Road Traffic. In American English, the terms "driver license" or "driver's license" are used. In Australian English, Canadian English and New Zealand English, the terms "driver licence" or "driver's licence" are used while in British English the term is "driving licence". In some countries the term "driving license" is used. The laws relating to the licensing of drivers vary between jurisdictions. In some jurisdictions, a permit is issued after the recipient has passed a driving test, while in others a perso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reckless Driving
In United States law, reckless driving is a major moving violation related to aggressive driving that generally consists of driving a vehicle with willful or wanton disregard for the safety of persons or property. It is usually a more serious offense (law), offense than careless driving, improper driving, or driving without due care and attention, and is often punishable by fine (penalty), fines, imprisonment, or the suspension or revocation of one's driver's license. In Commonwealth of Nations, Commonwealth countries, the offense of dangerous driving applies. Reckless driving has been studied by psychologists who found that reckless drivers score high in risk-taking personality traits; however, no one cause can be assigned to the mental state. Depending on the jurisdiction, reckless driving may be defined by a particular mens rea, subjective mental state that is evident from the circumstances, or by particular driver actions regardless of mental state, or both. State laws A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sleep-deprived Driving
Sleep-deprived driving (commonly known as tired driving, drowsy driving, or fatigued driving) is the operation of a motor vehicle while being cognitively impaired by a lack of sleep. Sleep deprivation is a major cause of motor vehicle accidents, and it can impair the human brain as much as inebriation can. According to a 1998 survey, 23% of adults have fallen asleep while driving.Peters, Robert D"Effects of Partial and Total Sleep Deprivation on Driving Performance" US Department of Transportation, February 1999. According to the United States Department of Transportation, twice as many male drivers than female drivers admit to have fallen asleep while driving. In the United States, 250,000 drivers fall asleep at the wheel every day, according to the Division of Sleep Medicine at Harvard Medical School and in a national poll by the National Sleep Foundation, 54% of adult drivers said they had driven while drowsy during the past year with 28% saying they had actually fallen asleep ...

Impaired Driving
Driving under the influence (DUI) is the crime of driving, operating, or being in control of a vehicle while one is impaired from doing so safely by the effect of either alcohol (see drunk driving) or some other drug, whether recreational or prescription (see drug-impaired driving). Multiple other terms are used for the offense in various jurisdictions. Terminology The name of the offense varies from jurisdiction to jurisdiction and from legal to colloquial terminology. In various jurisdictions the offense is termed "driving under the influence" f alcohol or other drugs(DUI), "driving under the influence of intoxicants" (DUII), "driving while impaired" (DWI), "impaired driving", "driving while intoxicated" (DWI), "operating while intoxicated" (OWI), "operating under the influence" (OUI), "operating vehicle under the influence" (OVI), "drunk in charge", or "over the prescribed limit" (OPL) (in the UK).

Speeding
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 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 govern ...
