These are defined in the Marine and Safety (Pilotage and Navigation) Regulations 2017 and relate to which navigational spans certain vessels can use and the movement of vessels in the vicinity of these bridges.

There are special rules for going through the Tasman Bridge. These are defined in the Marine and Safety (Pilotage and Navigation) Regulations 2017 and relate to which navigational spans certain vessels can use.
- Vessels over 25 metres in length, or tugs, may use the main navigation span and only after permission is granted from Tasports. No other vessels are to pass through the main navigation span;
a. Where a vessel intends to pass under the main span, a long, 10 second, horn blast will notify the vessel’s intention
- Vessels between 15 -25 metres in length should pass through the designated secondary span;
a. If the vessel is proceeding upstream the designated span is the aperture under the secondary navigation span immediately eastward of the aperture of the main navigation span.
b. If the vessel is proceeding downstream the designated span is the aperture under the secondary navigation span immediately westward of the aperture of the main navigation span.
- Vessels not exceeding 15 metres in length and recreational vessels must not cause or allow the vessel to pass under the bridge through the main navigation span, or the secondary navigation spans either side of the main navigation span, unless otherwise authorised to do so by MAST. Boaters should be aware of expected shipping movements before going out on the water. These are published in daily newspapers and can be found on the Tasports website.
