Wicked Campers' use of obscene slogans has caused an uproar in Queensland where the premier has urged the public to boycott the campervan hire company.
Annastacia Palaszczuk wants people to stop using Wicked Campers until offensive and derogatory slogans are removed from their fleet.
Ms Palaszczuk called for the boycott on Tuesday after Queensland's peak motoring body, the RACQ, urged the state government to crack down on the company for flouting advertising standards on the roads.
The premier said Attorney-General Yvette D'Ath would examine ways to stop Wicked's obscene slogans, but advertising breaches were a national issue.
She urged the public to take action in the first instance.
"The first step is people can boycott them," Ms Palaszczuk said.
"It is unacceptable to have those vile slogans on those vans."
She also called Wicked to censor itself, particularly by removing slogans that degrade women.
RACQ spokesman Paul Turner said the government should direct resources towards making the company accountable instead of "redundant crackdowns on ride-sharing services" like Uber.
Mr Turner said many of Wicked's slogans encouraged dangerous driving, were pornographic and were derogatory towards women.
