If there is an existing policy:

Find out what the policy does and does not include. Does it ban all alcohol advertisements on public transport?

Find out which agency which is responsible for enforcing the policy. Sometimes, it is the responsibility of the bus company rather than the Council to adhere to and enforce the policy.

- Making a complaint

You can make a complaint if you believe there has been a breach of the policy.

Gather as much information as possible about the breach, e.g. time, place, bus route, alcohol advertisement.

Report the complaint to the group which enforces the policy.

Where to find further information  

Public Transport Agency – raise your concern to the public transport agency in your region so that they can commence investigation. Even if they are not responsible for advertisements on public transport, it is still worthwhile to raise the concern to them because they will have the contract with bus companies.
