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.
How are prohibitory signs classified in Australia?
In NSW, regulatory signs include No Entry, prohibited turns and speed restrictions. Check another jurisdiction’s rules separately.

Can a no-turn restriction apply only to certain vehicles or hours in Australia?
New South Wales example: Yes, where the local sign system provides a supplementary condition or exemption, such as a vehicle class, time or authorised access. Without a valid exception, comply with the prohibited movement shown.
