T-Junction

T-Junction is a type of road shape like a T.

The aim of the lesson, is that you will be required to demonstrate your ability to learn how to carry out the correct procedures. when merging from minor roads into major roads. With the objective being that by the conclusion of the lesson. you should have a good understanding of what is required. and should be capable of carrying out these varied emerging sequences.

  • Aims and objectives of the lesson.
  • Different types of control at "T. junctions. such as traffic lights. stop signs. give way signs and unmarked junctions.
  • Adoption of the mirrors — signal — position — speed — look sequence.
  • Achieving the correct road position, including narrow roads, when emerg¬ing to the right and left.
  • Differences involved in reducing speed, between uphill and downhill approaches.
  • Advantages of making use of block gear changes.
  • Possible problems associated with coasting when emerging.
  • Giving precedence, to pedestrians, when emerging.
  • Differences between procedures when dealing with open and closed junci ions.
  • Taking effective observation to both the left and right Wore emerging.
  • Accurate assessment of the speed and distance of vehicles from the right and left when emerging.
  • Additional safety margins required when emerging and turning into the path of approaching traffic.

Stop signs

When approaching junctions controlled by stop signs and road markings. they must ensure that they come to a complete stop with die front bumper of the car. in a position which is just short of the continuous whitc line. or alterna¬tively half a car length. behind any station, vehicle in front. Having stopped, if they arc going to have to wait for a reasonable period of time. they should immediately apply thc parking brake. before preparing the car for moving off again. Where necessary. they should wait for any passing traffic front their right or left. then proceed as soon as it is safc to do so.

Give way signs

Whcn approaching junctions controlled by give way signs and or markings. they must be awarc that the decision as to whether to proceed or stop. should be made in accordancc with the zones of vision, and the traffic conditions which exist at that panicular timc.

Unmarked

When they are dealing with unmarked junctions where there are no signs or road markings, these junctions should be dealt with in exactly the same way, as when dealing with junctions with give way signs or markings.

Mirror-signal - maneuver

When emerging whenever they receive directions for a right or left turn, the mirror — signal — position — speed — look sequence should be used in exactly the same manner as covered when approaching right and left turns in the pre¬vious lesson. They should make use of the interior minor first, followed by the appropriate right or left exterior mirror, well before considering a direction signal, this action will enable them to safely assess the speed and distance of any following traffic. In addition to checking these mirrors before signaling, both the interior and appropriate door mirrors should always be checked again. just before they start to emerge onto enter major roads. They must be capable of giving the correct directional signal in good time, well before they take up the correct road position. When giving either right, or left turn signals, they should be given as early as possible, other than in locations where there is a junction on the left or right quite close to the junction.

Speed

When emerging. whether they are turning right or left. They should reduce speed by initially removing pressure from the accelerator pedal. before where necessary, starting to apply progressive pressure to the foothrake pedal. They should reduce speed to enable them to have sufficient time, to take early ob¬servations to assess the traffic situation from both directions. to enable them to decide whether or not, it will be possible for then) to continue with their proposed emerge. or bring the car to a stop if necessary.

Gears

They should be aware of the advantages of making usc of block gear changes on the approach where appropriate. such as from either four to two, or three to onc. They should ensure that they select the appropriate gear in accordance with the view which can be obtained to both thc left and the right on the a, proach, before reaching the give way or stop lines at thc junction, The selec¬tion of the appropriate gear for emerging, will depend on the circumstances which exist at that time, for most open junctions this will normally be second gcar, and for closed junctions this would always require first gear.

Coasting

When selecting the appropriate gear on the approach to open or closed junc¬tions, which may be second or first gear. they must ensure that they have allowed sufficient time to release the clutch pedal fully, to avoid coasting. They must be aware that coasting up to junctions is a potentially dangerous practice and must always be avoided. This fault may occur, on occasions where they have kept the clutch pedal down to the floor, after having selected a lower gear, or where they have selected the "neutral" position, while the car is still moving.

Observation

They must take effective observation in both directions before emerging, un¬der normal circumstances, it is advisable for them to take at least two looks in either direction, before reaching a decision as to whether to proceed or stop. When emerging they must be able to assess whatever zones of vision is going to be available to them, before taking any observations. Where their view to either the right, or left is restricted by buildings, walls, fences, hedges, parked vehicles or pedestrians that they must ensure that the car is brought forwards into a position, where effective observation can be taken in both directions. Where their view is restricted in such a way, they should be advised to inch forwards, by means of clutch control, to a position where effective observation can be taken.

Emerging

At junctions controlled by either give way signs and road markings, or just give way lines, they should look, assess, and then reach a decision as to whether, or not it is possible to continue without stopping, then take the appropriate action in accordance with that decision. They must be able to mac an accurate assessment, of judging the speed and distance of other road users from both directions, taking care not to cause any inconvenience to other road users, particularly when turning into the path of these approaching vehicles, such as turning left with a vehicle approaching from the right, and turning right with a vehicle approaching from the left. Where necessary, they must be able to emerge safely into a gap, without causing other traffic to either slow down, swerve, or stop.

Position right

They should attempt to achieve the correct position on the road prior to turn¬ing right, which should be varied in accordance with are type of road layout, which has been marked out in that particular location, for most right turns, they should gradually move across towards a position, which is just to the left of the center line, other than when they are driving in narrow roads, where they should maintain their normal safety line position, also where there are lane arrows marked out on the road surface, it is essential that they choose the lane which is marked with right turn arrows, or alternatively when turning right at the end of a one-way street they should move into the extreme right hand lane.

Position left

They must be aware of the dangers of approaching left turns from a position, which is either too far away from, or too close to the hand kerb. When turning left they should maintain the normal safety line position, approxi¬mately a meter from the left hand kerb, other than on occasions where they are already driving past stationary vehicles, or other obstructions on the left, in which case they should gradually move into a position which is reasonably close to the left side of the road. When they are when turning left, they should follow the natural curve of the road round to the left, where one exists. In loca¬tions where filter lanes may exist, they should obey any left turn lane arrows marked out on the road surface, by moving into that lane.

Pedestrians

When approaching and intending to emerge from a minor road into a major road, and turning either right, or left at “T” junctions, they must give priority to any pedestrians who may be crossing over the exits from these side roads.
