Prohibitory signs
A prohibitory sign is a traffic sign that tells drivers what is not allowed on that specific road or in that situation. These signs impose restrictions such as no entry, no overtaking, no parking, speed limits, or bans on certain types of vehicles. Their purpose is to clearly indicate actions that are forbidden to ensure safety, maintain traffic flow, and protect vulnerable road users.
