Information about the junction ahead is usually given at least 500m in advance to give you time to move to the left most lane. Countdown markers may also be used to indicate the distance in hundreds of metres to the start of the deceleration lane. A direction sign is erected immediately before the junction to give information about the route and junction ahead. Deceleration arrow is used to indicate the start of a deceleration lane which gives you time and space to begin reducing your speed. A direction sign is erected at the junction to provide information about the junction. The slip road leads you to a junction with an ordinary road or to another dual carriageway. Some slip roads may have sharp bends which can only be taken safely by further reducing your speed.
Joining a major trunk road (signs in blue)/an expressway (signs in green)
A slip road leads you into an acceleration lane. Watch the traffic on the trunk road and adjust your speed so that you can join the nearest lane in a suitable gap. After joining the lane, stay in the lane long enough to become accustomed to the speed of the traffic before trying to change lanes as necessary.

These are informatory merging signs used before the merge at junctions on expressways.
On wide busy roads, and particularly on expressways and trunk roads, direction signs may be placed on gantries above the road. On expressways, the direction signs are green in colour.
Road Sign
Arrows below the destinations mean 'Select your destination and get in lane'. Do so in good time. The sign above generally means there is a lane-drop for the exit and the number of lanes on the main road will be reduced from four to three.
Road Sign
Where there is no loss of lane beyond the junction, the panel containing the sloping upward arrow in the sign above indicates the exit destinations, while the panel containing the downward facing arrows gives destinations for the main road. Keep left if you are leaving the main road.
