Supplementary plates are crucial additions to primary road signs, providing vital context for their application. They clarify specific conditions such as distances, time restrictions, vehicle types, and parking rules, fundamentally altering how you must interpret and act upon the main sign. Mastering these plates is essential for both passing your driving theory exam and ensuring your safety on the road by correctly understanding traffic regulations.
An explanation of how Supplementary Plates (T) road signs apply in real traffic situations in Sweden. Learn where these signs are typically placed, what drivers are expected to do when they appear, and how correct reactions help you stay safe, avoid fines, and succeed in your Swedish driving theory exam.
Supplementary plates are frequently encountered alongside main traffic signs, significantly influencing their meaning and application. You'll see 'Distance to Yield Requirement' (T3) or 'Distance' (T2) plates indicating how far ahead you need to prepare to yield or slow down, often on approach to intersections or hazards. In urban areas, plates like 'Parking Disc' (T17) and 'Permitted Parking Time' (T18) or 'Parking Ticket' (T20) dictate how and where you can legally park your vehicle, often with time limits or specific vehicle types specified by a 'Symbol Plate' (T8) or 'Text' (T22). On busy roads, 'Length of Road Section' (T1) or 'Extent' (T11) plates might warn you about upcoming roadworks or restrictions that apply for a specific distance. 'Gross Weight Threshold' (T5) plates are common near bridges or roads with weight limits. 'Time Indication' (T6) plates are vital for understanding when a parking restriction or other rule is active, ensuring you avoid fines. Understanding these plates collectively is key to obeying traffic rules accurately and navigating complex traffic situations safely.

Clear answers to common questions about the Supplementary Plates (T) road sign category. Use this FAQ to review tricky rules, understand how these signs appear in exam scenarios, and remove confusion that often leads to mistakes in the Swedish driving theory exam in Sweden.
The main purpose of supplementary plates is to provide additional information that modifies or clarifies the meaning of the main traffic sign they are placed under. They help drivers understand the specific context in which the primary sign's rule applies, such as for a certain distance, time, vehicle type, or under specific parking conditions.
You generally know if a supplementary plate applies to you by reading it in conjunction with the sign above it. For example, a 'No Stopping' sign with a 'Text' (T22) plate specifying 'Except buses' means the restriction applies to all vehicles except buses. Similarly, a parking sign with a 'Residents' (T19) plate means the parking rule is only for residents. Always read the main sign and the plate(s) together.
The 'Distance' (T2) plate usually indicates the distance to a hazard or a point where a rule begins. The 'Distance to Yield Requirement' (T3) plate specifically tells you how far away the actual intersection or point is where you must yield. Both indicate a distance, but T3 is specifically linked to the obligation to yield.
Yes, it is common for a main traffic sign to have multiple supplementary plates placed beneath it. When this happens, all the conditions on the plates apply simultaneously to the main sign's instruction. For instance, a parking sign might have a plate for 'Permitted Parking Time' (T18) and another for 'Parking Ticket' (T20), meaning you can only park for the specified time if you pay with a ticket.
Absolutely. Understanding supplementary plates is a critical part of the driving theory test. Examiners frequently include questions that test your ability to correctly interpret how these plates alter the meaning of standard road signs. Misinterpreting them can lead to incorrect answers on the test and unsafe driving in practice.
