The TT-18 sign means that motor vehicles are prohibited from entering a certain area or performing an action like overtaking or turning. It's a binding rule that applies from the sign onwards unless a supplementary plate or an end sign modifies it. You must not proceed with your vehicle if it falls under the restriction.
The TT-18 sign doesn't necessarily mean you must stop, but it prohibits motor vehicles from entering or proceeding. If your vehicle is classified as a 'motor vehicle' and is not exempted by a supplementary plate, you must not enter the restricted area or perform the prohibited action. You should choose an alternative legal route.
Supplementary plates provide crucial details about the TT-18 restriction. They might specify which types of motor vehicles are prohibited (e.g., only trucks, or only vehicles over a certain weight), the distance of the restriction, specific times of day, or the direction in which the prohibition applies. Always read these plates carefully.
A common mistake is assuming the sign doesn't apply to you without checking a supplementary plate, or following other vehicles blindly into a restricted zone. Learners might also forget that the prohibition lasts until an 'End of Prohibition' sign is seen. Understanding the precise scope of the restriction shown on any additional plate is key for the exam.
No, you should never ignore the TT-18 sign just because other drivers do. Traffic laws and signs are binding for all drivers. Assuming an exemption based on others' behaviour is a dangerous mistake and can lead to penalties and accidents. Always adhere to the traffic signs yourself.
