Get clear, practical answers to the most common questions about the TT-20 - Width limit road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the Turkish driving theory exam in Turkey.
The TT-20 sign means that vehicles with a width exceeding the specified limit are prohibited from entering the restricted area or continuing on that road. This is a crucial safety sign to prevent accidents in narrow passages or structures.
You must check the width of your vehicle and compare it to the limit indicated on the sign or any supplementary plate. If your vehicle is wider than permitted, you must not proceed and should find an alternative, legal route.
Not necessarily. Supplementary plates beneath the TT-20 sign can specify that the restriction applies only to certain types of vehicles (e.g., lorries, buses), or for specific durations or directions. Always read the entire sign assembly carefully.
A common mistake is assuming the sign doesn't apply to them without checking, or failing to read supplementary plates. Another error is proceeding because other vehicles are, or waiting too long to decide on an alternative route. Remember, it's a binding prohibition.
The restriction indicated by the TT-20 sign continues until you see a sign that explicitly cancels it, often an 'End of Prohibition' sign or a similar instruction. Do not assume the restriction has ended just because the narrow section seems to be over.
