Headlamps and other lighting equipment

Most low-beam headlamps are specifically designed for use on one side of the road or the other. Headlamps for use in LH-traffic countries have low-beam headlamps that "dip to the left", i.e., the light is distributed with a downward/leftward bias to show the driver the road and signs ahead without blinding oncoming traffic. Headlamps for RH-traffic countries have low beams that "dip to the right", with most of their light directed downward/rightward. Within Europe, when driving a vehicle with RH-traffic headlamps in a LH-traffic country or vice versa for a limited time (as for example on holiday or in transit), it is a legal requirement to adjust the headlamps temporarily so that the wrong-side hot spot of the beam does not dazzle oncoming drivers. This may be achieved by adhering blackout strips or plastic prismatic lenses to a designated part of the lens, but some varieties of the projector-type headlamp can be made to produce a proper LH- or RH-traffic beam by shifting a lever or other movable element in or on the lamp assembly.

Because blackout strips and adhesive prismatic lenses reduce the safety performance of the headlamps, most countries require all vehicles registered or used on a permanent or semi-permanent basis within the country to be equipped with headlamps designed for the correct traffic-handedness. In the UK, US government and military personnel who brought RHT/LHD cars with them used to 'trade' headlamp assemblies with a person returning to the US[citation needed]. The newcomer then had proper LHT lights and the US-bound returnee had proper RHT ones again. As most 50s-80s headlamps were interchangeable, this 'swap' could save motorists time and money.

Anecdotal reporters have observed the requirement to adjust headlamps for the traffic-handedness of the country is increasingly flouted, and is now rarely enforced by European police forces. In France, this may be due in part to the 1993 deletion of the previous requirement for Selective yellow headlamp light; foreign-registered vehicles are now much less conspicuous at night.

Without sidecars attached, motorcycles, motor scooters, mopeds, and bicycles are almost symmetric with their handlebars in the centre. However, motorcycles are often equipped with automotive-type asymmetrical-beam headlamps that likewise require adjustments or replacement when brought into a country with opposite traffic-handedness.

Vehicles

Legal restrictions on "wrong-hand drive" vehicles

For safety reasons (and in some cases political or economic reasons), some countries have banned the sale or import of vehicles with the steering wheel on the "wrong" side.

In Australia this is the case with non-vintage (i.e. less than 30 years old) LHD vehicles, with the result that Australians who import such vehicles usually must pay sometimes thousands of dollars to convert them to RHD. The exceptions are for vehicles registered in Western Australia and the Northern Territory - both which have at various times hosted U.S. military facilities and had vehicles imported, used and sold by U.S service personnel in circulation. The Australian Capital Territory (ACT) previously allowed non-vintage LHD vehicles to be registered, but changed its legislation some years ago.

In New Zealand, LHD vehicles may be privately imported, and driven locally under a LHD permit. Since 1999, only LHD vehicles older than 20 years or cars owned and operated for at least 90 days may be privately imported. Diplomats and Operation Deep Freeze personnel are exempted from these restrictions.

In the Philippines, RHD vehicles especially cars, are banned. Public buses and vans imported from Japan are converted to LHD, and passenger doors are created on the right side. However, some vans keep their doors on the left side, leading to the odd (and dangerous) situation in which passengers have to exit toward oncoming traffic.

Cambodia banned the use of RHD cars, many of which were smuggled from Thailand, from 2001, even though RHD vehicles accounted for 80 percent of vehicles in the country. The government threatened to confiscate all such vehicles unless they were converted to LHD, in spite of the considerable expense involved. According to a BBC report,[10] changing the steering column from right to left would cost between US$600 and US$2,000, in a country where average annual income was less than US$1,000.

Although it drives on the right, North Korea has imported various used RHD vehicles from Japan, from tourist buses to Toyota Land Cruisers.

However, many used vehicles exported from Japan to countries like Russia and Peru are already converted to LHD. But even if the driver's position is left unchanged, some jurisdictions require at least readjustment of the headlights.

Singapore bans LHD vehicles from being imported for personal local registration, but temporary usage by tourists of LHD vehicles is allowed. However, diplomatic vehicles in Singapore are exempt from the RHD-only ruling, and there are a few hydrogen and fuel cell powered LHD vehicles currently undergoing trials in Singapore.

In Taiwan, Article 39 of the Road Traffic Security Rules (zh:道路交通安全規則) require a steering wheel to be on the left side of a vehicle to pass an inspection when registering the vehicle, so RHD vehicles may not be registered in Taiwan. This rule does not apply retroactively so older RHD vehicles may continue to be legally driven.

In Trinidad and Tobago, LHD vehicles are banned except for returning nationals who were resident in a foreign country and are importing a vehicle for personal use. LHD vehicles are also allowed to be imported for use as funeral hearses.

In West Africa, once-British Ghana and Gambia have also banned RHD vehicles. Their traffic has been changed from on the left to on the right. Ghana prohibited new registrations of RHD vehicles after 1 August 1974, three days before the traffic change on 4 August 1974. RHD vehicles may be imported only temporarily into Sierra Leone, for example for humanitarian programmes, but must be rexported at the end of the operation.

Most of the above bans on RHD and LHD vehicles apply only to locally-registered vehicles. Countries that have signed the 1968 Vienna Convention on Road Traffic are not allowed to make such restrictions on foreign-registered vehicles. Paragraph 1 of Annex 5 states "All vehicles in international traffic must meet the technical requirements in force in their country of registration when they first entered into service". Therefore all signatory countries and most non-signatory countries allow the temporary import (e.g. by tourists) of foreign-registered vehicles, no matter which side the steering wheel is on. Oman, which has not signed the convention bans all foreign-registered RHD vehicles.[11]

Both RHD and LHD vehicles may generally be registered in any European Union member state, but there are some restrictions and regulations. Slovakia, despite being a member of the European Union, does not allow the local registration of RHD vehicles,[12] even if the vehicle is imported from one of the four EU countries that drive on the left (UK, Ireland, Cyprus, and Malta). Lithuania has prohibited new RHD vehicle registration since 1993.

Left-hand traffic

  • Oncoming traffic is seen coming on the right side.
  • Right-turning traffic must cross oncoming traffic.
  • Most traffic signs facing motorists are on the left side of the road.
  • Traffic on roundabouts (traffic circles or rotaries) goes clockwise.
  • Pedestrians crossing a two-way road should first look for traffic from their right.
  • Most vehicles have a right-hand driver's position, instruments and controls.

Right-hand traffic

  • Oncoming traffic is seen coming from the left.
  • Left-turning traffic must cross oncoming traffic.
  • Most traffic signs facing motorists are on the right-hand side of the road.
  • Traffic on roundabouts (traffic circles or rotaries) goes anticlockwise (counter-clockwise).
  • Pedestrians crossing a two-way road should first look for traffic from their left.
  • Most vehicles have a left-hand driver's position, instruments and controls.

Traffic directionality

Traffic directionality refers to regulations requiring all vehicular traffic to keep either to the left or the right side of the road. Whether the right or the left is specified depends on the laws of each country. This is so fundamental to vehicular transport that it is commonly referred to as the rule of the road[1]. The purpose of the rule of the road is to facilitate traffic flow and reduce the likelihood of head-on collisions. About 34% of the world by population drive on the left, and 66% on the right. By roadway distances, about 28% drive on the left, and 72% on the right,[2] even though originally most traffic drove on the left worldwide.[3]

In a more technological sense

The term has also been used for devices installed in a car, which observe the driving through electronic means, and inform the driver or a third party. Back Seat Drivers are moving Up Front by Anne Eisenberg in the New York Times, Feb 4, 2007.

Back seat driver

A back seat driver is a passenger in a vehicle who is not in control of the vehicle and does not appear to be comfortable with the skills of the current driver and/or feels the need to tutor said driver.

Some backseat drivers exhibit this type of behaviour simply because they feel unsafe or out of control since they are not driving the vehicle and therefore are nervous and jumpy and overly anxious to give suggestions and criticisms regarding the current drivers actions. The Maine Department of Transportation has a web poster "Are you a Good Back Seat Driver?" asking "True or False: Being a Backseat Driver means it is okay to be noisy or distracting to the driver as long as you are giving them safety tips." The Inland Register produced by the Roman Catholic Diocese of Spokane makes use of it in a sermon: "Even our phrase “back-seat driver” reflects this new-found freedom. Which of us who has graduated to the status of driver enjoys a passenger, especially one out of reach in the back seat, who seems to know how to drive better than we do? "

The Art of being a Backseat Driver in the San Bernadino sbsun summarizes various comments of the sort otherwise found in multiple blogs. Some are specialized, such as the Back Seat Driving blog, formerly the "LA Car Blog."

A famous example of a back seat driver is Hyacinth Bucket on the British sitcom Keeping Up Appearances. The term is also used in Backseat Drivers from Beyond the Stars, an episode of Invader Zim A poem "The Backseat Driver" by Parick G Hughes appears in the Northern Ireland BBC Writer's Showcase.

It is even used as a deliberate game. In All things Considered on NPR for July 19, 2006, there is an account of a "Back Seat Driver competition in Forest City, Iowa. ... The event -- in which a driver races backward while blindfolded and instructed by the voice of a companion over an intercom -- is in its eighth year." It has even been noticed by People's Daily .

Minimum motorist ages

The minimum age required to be a motorist varies depending on the country. The most common age is 18. Here are the ages required in some countries (in alphabetical order), note that some regions of the countries may start at a different age than other regions, this is just the minimum age requirement to drive.

Driving laws

In most countries, the use of public roads is heavily governed by law. Laws cover the construction and maintenance of roads, the construction and use of vehicles, the rules of the road, the requirements for motorist licensing (see Driver's license), vehicle registration (see License plate), vehicle taxation, safety inspections and compulsory insurance for heavy motor vehicles. These laws reflect the high degree of responsibility which is imposed upon both the drivers and manufacturers of vehicles (especially heavy motor vehicles) to make them as safe in use as they can possibly be.

Motorists are almost universally required to take lessons with an approved instructor and pass a driving test before being granted a license. The trend has been towards increasingly tougher tests in recent decades. Almost all countries allow all adults with good vision to apply to take a driving test and, if successful, to drive on public roads. Saudi Arabia, however, bans women from driving vehicles (whether pedal or motor powered) on public roads. Saudi women have periodically staged driving protests against these restrictions.

In many countries, even after passing one's driving test, new motorists may be initially subject to special restrictions. For example, in Australia, novice drivers are required to carry "P" ("provisional") plates, and are subject to lower speed limits, alcohol limits, and other restrictions for their first two years of driving. This varies between states.

Driving as a mental skill

Driver error is an important factor in collisions, which result in the death of many thousands of people annually (see also car accident). Preventing collisions involves more than just fong the rules of the road literally; defensive driving also involves the cultivation of good habits, maintaining attention, and a thoughtful, cooperative attitude. One of the latest researches showed that music could also affect the driver's attention on the road: classic music leads to clamness, while hard-rock makes the driver accelerate. Both could lead to car accidents, since both make the driver lose concentration.[1]

Avoiding or successfully handling an emergency driving situation can involve any of the following skills:

  • Reversing
  • Decision Making
  • Evasive maneuvers
  • Inflating the tires properly
  • Pursuit driving
  • Proper hand placement and seating position
  • Skid control
  • Steering and braking techniques
  • Understanding vehicle dynamics

Driving as a physical skill

n terms of the basic physical tasks required, a driver must be able to control direction, acceleration, and deceleration. For motor vehicles, the detailed tasks include:
  • Starting the vehicle's engine with the starting system
  • Setting the transmission to the correct gear
  • Depressing the pedals with one's feet to accelerate, slow, and stop the vehicle, and if the vehicle is equipped with a manual transmission, to modulate the clutch
  • Steering the vehicle's direction with the steering wheel
  • Operating other important ancillary devices such as the indicators, headlights, windshield wipers, and operating the stick shift in some cases when the vehicle is not an automatic
  • Watching the road conditions in all directions around the vehicle (including frequent checks behind the vehicle using mirrors) to monitor the relative location of other vehicles (including bicycles), and pedestrians

Driving skills

Driving in traffic is more than just knowing how to operate the mechanisms which control the vehicle; it requires knowing how to apply the rules of the road (which govern safe and efficient sharing with other users). An effective driver also has an intuitive understanding of the basics of vehicle handling.

Driving

Driving is the controlled operation of a land vehicle, usually a motor vehicle such as a truck, boat, or car. Although direct operation of a bicycle, a mounted animal (not including chariot operation) or a motorcycle (at least in the United Kingdom, the United States and Canada) is commonly called riding, such operators are usually considered to be drivers in a legal sense and required to obey those rules of the road which apply to all drivers.
