What is a junction in a road?
Introduction – When two or more roads meet from different directions, they do so at a junction. There are several types of junctions and each has its own characteristics. On your driving lessons, you will learn how to approach, emerge and remain safe when at a junction.
You’ll also learn how to position your vehicle and how to anticipate the actions of other road users at junctions. A junction is a point at which two or more roads meet. In the UK junctions are used to control traffic, and they come in various shapes, sizes and layouts. They make up a fundamental part of the road system and you need to learn how to deal with junctions safely, as they are considered accident hotspots.
The most common driving test fault is inadequate observation at junctions. Incorrect positioning when turning right at a junction also makes the top 10 list, so you’ll be unable to pass your test if you haven’t mastered the different types of junction you’re likely to face on your driving test.
What is a junction in simple words?
noun
- a place or point where two or more things are joined, as a seam or joint.
- a place or point where two or more things meet or converge.
- a place or station where railroad lines meet, cross, or diverge.
- an intersection of streets, highways, or roads.
- something that joins other things together: He used the device as a junction between the branch circuit and the main power lines.
First recorded in 1705–15; from Latin junctiōn- (stem of junctiō ), equivalent to junct(us), past participle of jungere “to join” ( jung- join + -tus past participle suffix) + -iōn- -ion
What is an example of junction?
For example, your body has nerve junctions — the places where your nerves come together. You may go swimming at the junction of two rivers. Junction can also refer to something that connects things, like a junction you use to connect electrical cords.
What is a junction in British English?
Junction in British English (ˈdʒʌŋkʃən ) noun.1. a place where several routes, lines, or roads meet, link, or cross each other.
Why is it called a junction?
Etymology – The word “junction” derives from Latin iunctus, past participle of iungere, to join. The word “junction” in this context may also refer to:
The general locality of a given interchange A specific interchange on a major road, e.g. motorway, This is the common use in the United Kingdom, For example, Milton Keynes is said to be “off junction 13 ” of the M1,
Is a junction a crossroad?
A crossroad is a junction, but not all junctions will be crossroads. A junction is when two or more roads meet or join, and a crossroads is where two roads intersect.
How do you identify a junction?
Locating a road junction – Approaching junctions inappropriately is a very common method of failing the driving test. During the test, it is important to locate a junction ahead as early as possible. Many learner driver are unaware of an approaching junction and realise far too late, often resulting in the need to stop the car too harshly, stopping over the give way line or the examiner having to use the dual controls.
- This is due to lack of appropriate observation.
- Whilst driving, look for signs of a junction up ahead.
- This can of course be the triangle Give Way warning sign, a Stop sign or traffic lights.
- Try and look for other indications of a junction such as cars passing in front up ahead, or you may be able to see give way road markings and lines.
Look at the UK road traffic signs section for examples of road signs. You will have to apply the MSN routine ( mirror, signal, manoeuvre ) if you intend on turning either left or right. We will cover this routine further in the next section. For further information, see:

What happens in a junction?
In a circuit, there can be places, called junctions, where several wires come together. Kirchhoff’s Junction Rule says that the current going into a junction must equal the current coming out.
What is a junction on a map?
At the highest level, junctions are fairly simple. These are place on a roadway where there is an intersection of some kind. More specifically, this is anywhere where there is, an at-grade intersection, restricted crossovers on divided highways, and terminal points for specific routes.
How many types of junctions are there?
Summary – Many cells in tissues are linked to one another and to the extracellular matrix at specialized contact sites called cell junctions. Cell junctions fall into three functional classes: occluding junctions, anchoring junctions, and communicating junctions.
- Tight junctions are occluding junctions that are crucial in maintaining the concentration differences of small hydrophilic molecules across epithelial cell sheets.
- They do so in two ways.
- First, they seal the plasma membranes of adjacent cells together to create a continuous impermeable, or semipermeable, barrier to diffusion across the cell sheet.
Second, they act as barriers in the lipid bilayer to restrict the diffusion of membrane transport proteins between the apical and the basolateral domains of the plasma membrane in each epithelial cell. Septate junctions serve as occluding junctions in invertebrate tissues.
The main types of anchoring junctions in vertebrate tissues are adherens junctions, desmosomes, focal adhesions, and hemidesmosomes. Adherens junctions and desmosomes connect cells together and are formed by cadherins, while focal adhesions and hemidesmosomes connect cells to the extracellular matrix and are formed by integrins.
Adherens junctions and focal adhesions are connecting sites for bundles of actin filaments, whereas desmosomes and hemidesmosomes are connecting sites for intermediate filaments. Gap junctions are communicating junctions composed of clusters of connexons that allow molecules smaller than about 1000 daltons to pass directly from the inside of one cell to the inside of the next.
- Cells connected by gap junctions share many of their inorganic ions and other small molecules and are therefore chemically and electrically coupled.
- Gap junctions are important in coordinating the activities of electrically active cells, and they have a coordinating role in other groups of cells as well.
Plasmodesmata are the only intercellular junctions in plants. Although their structure is entirely different, and they can sometimes transport informational macromolecules, in general, they function like gap junctions.

Is junction a roundabout?
Roundabout in La Crosse, Wisconsin The Hotel Indonesia Roundabout in Jakarta, Indonesia A roundabout, also known as a rotary or traffic circle or (in the Philippines and Portugal ) rotunda, is a type of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.
- Engineers use the term modern roundabout to refer to junctions installed after 1960 that incorporate various design rules to increase safety.
- Compared to stop signs, traffic signals, and earlier forms of roundabouts, modern roundabouts reduce the likelihood and severity of collisions greatly by reducing traffic speeds and minimizing T-bone and head-on collisions,
Variations on the basic concept include integration with tram or train lines, two-way flow, higher speeds and many others. For pedestrians, traffic exiting the roundabout comes from one direction, instead of three, simplifying the pedestrian’s visual environment.
Traffic moves slowly enough to allow visual engagement with pedestrians, encouraging deference towards them. Other benefits include reduced driver confusion associated with perpendicular junctions and reduced queuing associated with traffic lights, They allow U-turns within the normal flow of traffic, which often are not possible at other forms of junction.
Moreover, since vehicles that run on gasoline averagely spend less time idling at roundabouts than at signalled intersections, using a roundabout potentially leads to less pollution. When entering vehicles only need to give way, they do not always perform a full stop; as a result, by keeping a part of their momentum, the engine will produce less work to regain the initial speed, resulting in lower emissions.
What is the largest junction in England?
The biggest train station in the UK – While Waterloo may have been stripped of previous titles, it still holds a major accolade. With 24 platforms in use, it’s the largest train station in the UK. The largest station outside of London is Edinburgh Waverley, with 20 operating platforms.

What is a 3 road junction called?
3-Way Intersections The picture we posted was of a 3-way intersection, also called a T-intersection. As you can see in the image, there are no stops signs, only yield signs.
What is the difference between junction and cross?
Asked 5 years, 6 months ago Viewed 4k times 1) What is the difference between Corner, Junction, Intersection, Crossroad and Crossing? As per google dictionary the definitions are: Corner – a place where two or more streets meet. Junction – a point where two or more things are joined. Trishana Trishana 11 1 silver badge 3 bronze badges 1 I’ll answer all four of your questions in list form.
- They all theoretically mean similar things. However, in practice, they are used differently.
- Corners typically describe areas off the roads where sidewalks and buildings commonly are. There are typically four corners available to pedestrians where two roads meet. In the context of a conversation, it is normally easy to figure out which corner is being spoken about.
- An intersection is the point where two roads (or typically anything else) cross each other and continue going on. An intersection is on the road itself.
- A junction of two roads does not have to continue going on. Also, one of the roads can stop and the other can continue. (See https://www.usingenglish.com/forum/threads/181960-intersection-vs-junction )
- A crossroad (used in North America) is a road that joins two main roads or crosses a main road according to one of the definitions by google. Similar sources give similar definitions. This means crossroads are normally side roads or roads that are not as major that are used to get onto more major roads. A crossroad is the only one on this list that is a road rather than a certain point. However, I personally do not hear this term as often as terms like corner or intersection.
- Crossing and intersection can mean the same thing. However, an intersection is normally where two roads meet while a crossing is where a road and something else meets.
- It depends on where that specific place is. There is no proper way to state what is correct in this instance, but here’s how I as well as many others that I know use the words: We use “at the corner” for all cases except when a street is meeting with something like railroads. There, we like to use intersection.
- Again, it depends. I agree with what this link says about the word corner: http://inmadom-myenglishclass.blogspot.com/2014/05/in-on-or-at-corner.html, It gives brief and accurate descriptions of the different ways to use prepositions before corners.
- “Take the second left on Park Street” would mean the driver is already on Park Street and they are going to take the second left turn going onto another road. “Take the second left onto Park Street” would mean the driver is on another street and they are taking a left to get to Park Street. “Take the second left into Park Street” is technically the same in usage as onto, but I don’t hear it used much unless Park Street is the last street the driver is going to turn on before arriving at their destination.

Is an intersection a junction?
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.

3. Road junctions (170 to 183) – 170 Take extra care at junctions. You should
watch out for cyclists, motorcyclists and pedestrians including powered wheelchairs/mobility scooter users as they are not always easy to see. Be aware that they may not have seen or heard you if you are approaching from behindgive way to pedestrians crossing or waiting to cross a road into which or from which you are turning. If they have started to cross they have priority, so give way (see Rule H2)remain behind cyclists, horse riders, horse drawn vehicles and motorcyclists at junctions even if they are waiting to turn and are positioned close to the kerbwatch out for long vehicles which may be turning at a junction ahead; they may have to use the whole width of the road to make the turn (see Rule 221)watch out for horse riders who may take a different line on the road from that which you would expectnot assume, when waiting at a junction, that a vehicle coming from the right and signalling left will actually turn. Wait and make surelook all around before emerging. Do not cross or join a road until there is a gap large enough for you to do so safely.
Rule 170: Give way to pedestrians who have started to cross 171 You MUST stop behind the line at a junction with a ‘Stop’ sign and a solid white line across the road. Wait for a safe gap in the traffic before you move off. Laws RTA 1988 sect 36 & TSRGD regs 10 & 16 172 The approach to a junction may have a ‘Give Way’ sign or a triangle marked on the road.
If it is, then you should treat each half of the carriageway as a separate road. Wait in the central reservation until there is a safe gap in the traffic on the second half of the road. If the central reservation is too shallow for the length of your vehicle, wait until you can cross both carriageways in one go.
Rule 173: Assess your vehicle’s length and do not obstruct traffic 174 Box junctions. These have criss-cross yellow lines painted on the road ( download ‘Road markings’ ). You MUST NOT enter the box until your exit road or lane is clear. However, you may enter the box and wait when you want to turn right, and are only stopped from doing so by oncoming traffic, or by other vehicles waiting to turn right. Rule 174: Enter a box junction only if your exit road is clear Junctions controlled by traffic lights 175 You MUST stop behind the white ‘Stop’ line across your side of the road unless the light is green. If the amber light appears you may go on only if you have already crossed the stop line or are so close to it that to stop might cause a collision.
- Laws RTA 1988 sect 36 & TSRGD regs 10 & 36 176 You MUST NOT move forward over the white line when the red light is showing.
- Only go forward when the traffic lights are green if there is room for you to clear the junction safely or you are taking up a position to turn right.
- If the traffic lights are not working, treat the situation as you would an unmarked junction and proceed with great care.
Laws RTA 1988 sect 36 & TSRGD regs 10 & 36 177 Green filter arrow. This indicates a filter lane only. Do not enter that lane unless you want to go in the direction of the arrow. You may proceed in the direction of the green arrow when it, or the full green light shows. Rule 178: Do not unnecessarily encroach on the cyclists waiting area 178 Advanced stop lines, Some signal-controlled junctions have advanced stop lines to allow cycles to be positioned ahead of other traffic. Motorists, including motorcyclists, MUST stop at the first white line reached if the lights are amber or red and should avoid blocking the way or encroaching on the marked area at other times, e.g.
use your mirrors to make sure you know the position and movement of traffic behind you give a right-turn signal take up a position just left of the middle of the road or in the space marked for traffic turning right leave room for other vehicles to pass on the left, if possible.
180 Wait until there is a safe gap between you and any oncoming vehicle. Watch out for cyclists, motorcyclists, pedestrians and other road users. Check your mirrors and blind spot again to make sure you are not being overtaken, then make the turn. Do not cut the corner. Rule 180: Position your vehicle correctly to avoid obstructing traffic 181 When turning right at crossroads where an oncoming vehicle is also turning right, there is a choice of two methods
turn right side to right side; keep the other vehicle on your right and turn behind it. This is generally the safer method as you have a clear view of any approaching traffic when completing your turn left side to left side, turning in front of each other. This can block your view of oncoming vehicles, so take extra care. Cyclists and motorcyclists in particular may be hidden from your view. Road layout, markings or how the other vehicle is positioned can determine which course should be taken.
Rule 181: Left – Turning right side to right side. Right – Turning left side to left side Turning left 182 Use your mirrors and give a left-turn signal well before you turn left. Do not overtake just before you turn left and watch out for traffic coming up on your left before you make the turn, especially if driving a large vehicle. Rule 182: Do not cut in on cyclists 183 When turning
keep as close to the left as is safe and practicablegive way to any vehicles using a bus lane, cycle lane, cycle track or tramway from either direction, including when they are passing slow moving or stationary vehicles on either side.
