The T1 supplementary plate, often called a 'Length of Road Section' sign, is crucial for understanding the exact duration of other traffic rules. It works in tandem with main signs to show where a specific regulation, like a speed limit or parking restriction, begins and ends. Drivers must pay close attention to this plate to know precisely within which section of the road the main sign’s instruction is active, ensuring compliance and safe driving practices in Sweden.
Learn the key details of the T1 - Length of Road Section road sign, including its function, what it communicates to drivers, and how it applies in real traffic situations in Sweden. Use this overview to understand the sign clearly and recognise it confidently during the Swedish driving theory exam.
This supplementary plate is used to define the extent of a regulation along a stretch of road. It indicates where the rule begins and where it ends, so you know the exact section affected. You must apply the instruction from the sign above only within the marked section. It is commonly used with restrictions such as stopping, parking, speed, or other local rules. Always read it together with the main sign to avoid applying the rule too early or too late.

The T1 sign is a supplementary plate used with other traffic signs. Its purpose is to clearly indicate the start and end points of the road section where the main sign's rule applies. It defines the exact length or distance of the restriction or regulation.
You must read the T1 sign together with the main sign above it. Apply the main sign's rule only within the specific section indicated by the T1 plate. Once you pass the end point shown on the T1 sign, the rule no longer applies, and you can revert to the general traffic rules.
A common trap is assuming the main sign's rule applies indefinitely or from the moment you see it, without noting the T1 sign's limitations. Learners often forget to check the T1 plate for the end of the regulated section, leading to incorrect behaviour and potential fines or exam failure.
Yes, the T1 sign is versatile and can be used with various main signs, particularly those indicating prohibitions (like 'no stopping' or 'no parking'), restrictions (like speed limits), or other specific commands. Its function is always to quantify the extent of the main sign's message.
If the T1 sign shows both a start and an end point, it means the main sign's rule is only active within that precisely defined stretch of road. The regulation begins at the 'start' indicated and ceases to apply at the 'end' indicated. Outside this section, normal rules apply.
