The three-point turn (sometimes called a Y-turn, K-turn, or broken U-turn) is the standard method of turning a vehicle around to face the opposite direction in a limited space, using forward and reverse gears. This is typically done when the road is too narrow for a U-turn. This manoeuvre is a common requirement in driving tests.
The basic manoeuvre consists of driving across the road turning towards the offside kerb, reversing across the road to the original nearside kerb while turning, and driving forward towards the original offside kerb, now the nearside.In a narrow road or with a longer vehicle, more than three legs may be required to achieve a full 180 degree rotation.
"Three point turn" is the most common name in Australia, Canada, New Zealand, and in many regions of the United States.Less common terms are: "Y-turn", "K-turn", and Broken U-turn but in the UK, the official name is "Turning in the road (using forward and reverse gears)", and in Ireland it is called a "turnabout", because an acceptable turn may include more than three points.
A truck or lorry is a motor vehicle designed to transport freight, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "tractor".
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design.
Traffic lights, traffic signals, or stoplights – also known as robots in South Africa – are signalling devices positioned at road intersections, pedestrian crossings, and other locations in order to control the flow of traffic.
Left-hand traffic (LHT) and right-hand traffic (RHT) are the practices, in bidirectional traffic, of keeping to the left side and to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes called the rule of the road. The terms right- and left-hand drive refer to the position of the driver and the steering wheel in the vehicle and are, in automobiles, the reverse of the terms right- and left-hand traffic. The rule also includes where on the road a vehicle is to be driven, if there is room for more than one vehicle in the one direction, and the side on which the vehicle in the rear overtakes the one in the front. For example, a driver in an LHT country would typically overtake on the right of the vehicle being overtaken.
The handbrake turn is a driving technique used to deliberately slide a car sideways, either for the purpose of quickly negotiating a very tight bend, or for turning around well within the vehicle's own turning diameter.
A Michigan left or P-turn is an at-grade intersection design that replaces each left (farside) turn at an intersection between a (major) divided roadway and a secondary (minor) roadway with the combination of a right (nearside) turn followed by a U-turn, or a U-turn followed by a right (nearside) turn, depending on the situation. It is in use in numerous countries.
An automatic transmission is a multi-speed transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive the wheels over a wide range of speeds.
A transmission is a mechanical device which uses gears to change the speed or direction of rotation in a machine. Many transmissions have multiple gear ratios, but there are also transmissions that use a single fixed gear ratio.
A manual transmission (MT), also known as manual gearbox, standard transmission, or stick shift, is a multi-speed motor vehicle transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch.
A driving test is a procedure designed to test a person's ability to drive a motor vehicle. It exists in various forms worldwide, and is often a requirement to obtain a driver's license. A driving test generally consists of one or two parts: the practical test, called a road test, used to assess a person's driving ability under normal operating conditions, and/or a written or oral test to confirm a person's knowledge of driving and relevant rules and laws.
A jughandle is a type of ramp or slip road that changes the way traffic turns left at an at-grade intersection. Instead of a standard left turn being made from the left lane, left-turning traffic uses a ramp on the right side of the road. In a standard forward jughandle or near-side jughandle, the ramp leaves before the intersection, and left-turning traffic turns left off of it rather than the through road; right turns are also made using the jughandle. In a reverse jughandle or far-side jughandle, the ramp leaves after the intersection, and left-turning traffic loops around to the right and merges with the crossroad before the intersection.
A hook turn or two-stage turn, also known as a Copenhagen Left, is a road cycling manoeuvre or a motor vehicle traffic-control mechanism in which vehicles that would normally turn from the innermost lane of an intersection instead turn from the outermost lane, across all other lanes of traffic.
The Ministry of Transportation (MTO) is the provincial ministry of the Government of Ontario that is responsible for transport infrastructure and related law in Ontario, Canada. The ministry traces its roots back over a century to the 1890s, when the province began training Provincial Road Building Instructors. In 1916, the Department of Public Highways of Ontario (DPHO) was formed and tasked with establishing a network of provincial highways. The first was designated in 1918, and by the summer of 1925, sixteen highways were numbered. In the mid-1920s, a new Department of Northern Development (DND) was created to manage infrastructure improvements in northern Ontario; it merged with the Department of Highways of Ontario (DHO) on April 1, 1937. In 1971, the Department of Highways took on responsibility for Communications and in 1972 was reorganized as the Ministry of Transportation and Communications (MTC), which then became the Ministry of Transportation in 1987.
An advanced stop line (ASL), also called advanced stop box or bike box, is a type of road marking at signalised road junctions allowing certain types of vehicle a head start when the traffic signal changes from red to green. Advanced stop lines are implemented widely in Denmark, the United Kingdom, and other European countries but the idea was first conceptualized by transportation planner Michael Lynch for the city of Portland, Oregon, in response to numerous bike crashes at intersections.
A bootleg turn is a driving maneuver intended to reverse the direction of travel of a forward-moving automobile by 180 degrees in a minimum amount of time while staying within the width of a two-lane road. This maneuver is also known as a smuggler's turn, powerslide, or simply bootlegger.
The turning radius of a vehicle defines the minimum dimension of available space required for that vehicle to make a semi-circular U-turn without skidding. The Oxford English Dictionary describes turning circle as "the smallest circle within which a ship, motor vehicle, etc., can be turned round completely". The term thus refers to a theoretical minimal circle in which for example an aeroplane, a ground vehicle or a watercraft can be turned around.
An all-way stop – also known as a four-way stop – is a traffic management system which requires vehicles on all the approaches to a road intersection to stop at the intersection before proceeding through it. Designed for use at low traffic-volume locations, the arrangement is common in the United States, Canada, Mexico, South Africa, and Liberia, as well as in a number of, usually rural, locations in Australia where visibility on the junction approaches is particularly poor. The stop signs at such intersections may be supplemented with additional plates stating the number of approaches.
Driving licence in Thailand is a document that allows the holder to drive on any roads in Thailand and in other ASEAN states without an International Driving Permit. The minimum age to drive a motor vehicle is 18, and to drive a motorcycle is 15. Driving licence is issued and administered by the Department of Land Transport, Ministry of Transport and its branches, land transport offices across Thailand.
A protected intersection or protected junction, also known as a Dutch-style junction, is a type of at-grade road junction in which cyclists and pedestrians are separated from cars. The primary aim of junction protection is to help pedestrians and cyclists be and feel safer at road junctions.
The United Kingdom has specific types of pedestrian crossing.
