Traffic Joins the Main Carriageway
The traffic joins the main carriageway sign is a red triangular warning sign showing a thick main route with another road joining it.
It warns you that you are approaching a point where your road joins another carriageway, so you need to be prepared for traffic already travelling on that road.

Unlike a normal side-road warning, this sign is particularly important because you may need to give way to traffic on the main carriageway.
Look well ahead as you approach, check for other vehicles and judge their speed and distance carefully.
Do not assume that traffic on the main road will slow down or move over to let you join.
Traffic Joins the Main Carriageway
For the theory test, remember what the sign is actually warning you about: you are about to join the main carriageway and may have to give way to traffic already using it.
Reduce your speed if necessary, make effective observations and only join when you have a safe opportunity to do so.
