Continuation of Roads at Intersection
The sign indicates the continuation of roads at an intersection
When You See This Sign
When you see T15, quickly locate which main sign it belongs to and interpret the drawn continuation to know the direction the priority road has through the intersection. Adjust speed and lane choice according to the sign's display and follow the priority rules indicated by the main sign.
Rules & Regulations
- T15 is a supplementary sign and applies only together with a main sign (e.g., yield, stop, or priority road).
- The sign shows a schematic continuation of the roads at an intersection and should be interpreted together with the main sign to determine the direction of the priority road.
- T15 by itself does not grant right of way or priority; those are determined by the main sign or the traffic rules at the intersection.
- Adjust your lane position and driving accordingly to the direction shown on the sign, especially when the priority road turns.
Tips for Drivers
- First locate the main sign above or next to T15 to know who has priority before you enter the intersection.
- Reduce speed in good time and position your vehicle in the correct lane according to the sign's schematic image so you are not forced to change lanes at the last second.
- Be extra alert when the sign shows that the priority road turns—other road users may think the main road goes straight ahead.
- Use road markings and any arrows in the lane together with T15 to confirm your lane choice if the sign seems unclear.
Common Mistakes
- Believing that T15 alone gives the right of way or that it is an independent priority sign.
- Reading the sign's schematic image as an exact map scale or detailed lane layout instead of a simplified overview.
- Ignoring the supplementary sign because it is small or placed beneath another sign.

Road Sign: Continuation of Roads at Intersection
What does this sign show about the roads in an intersection?
- A It shows which roads continue through the intersection and how the main road runs.
- B It indicates that the intersection is one-way.
- C It means you are approaching a roundabout.
- D It means the road ahead is closed.
Exam Tip
On the theory test, you are often tested on whether you know that T15 is a supplementary sign and does not give priority by itself. Answer that the sign must be interpreted together with the main sign (e.g., priority road, yield, or stop).
Did You Know?
T15 is often used when the main road does not continue straight through the intersection but turns—the sign is placed to avoid misunderstandings about which road is the main road. The image is intentionally schematic so it can be read quickly by road users.
Frequently Asked Questions
Can T15 stand alone without another sign?
No, T15 is a supplementary sign and is always used together with a main sign that indicates, for example, yield or priority road. It alone does not change any rules at the intersection.
Does T15 show exactly how many lanes there are?
No, the sign shows a simplified continuation of the roads at the intersection and not exact lane divisions or scale. Use road markings and arrows in the lane for detailed lane choice.
What should I do if T15 seems to contradict road markings?
Check both the main sign and the road markings and be extra cautious if they appear to contradict each other. Reduce speed, signal, and follow the applicable priority rules as well as instructions from the main sign.
How do I interpret when the main road turns according to T15?
The marked continuation on the sign shows the direction the main road takes through the intersection, so position yourself in the lane that corresponds to that continuation. Be aware of other traffic that may think the main road continues straight ahead.
