The move targets vehicles like Wicked Campers, which have been criticised for having obscene slogans spray-painted on.

In February 2017, the ACT Government announced that vehicles bearing offensive slogans de-registered in other states will not be eligible for registration in the ACT.

These additional regulations mean vehicles bearing offensive language or images will not be able to be registered in the ACT.

The Wicked Campers' vans are commonly used by backpackers travelling Australia and are not often seen in the ACT.

But Road Safety Minister Shane Rattenbury said the ACT was committed to a national approach to ensure the vehicles were not able to find a "safe haven" in any jurisdiction.

Examples of words or images that the new laws apply to are those that are morally unacceptable, sexual material that is used in an exploitative or degrading manner, or negative words or images about any religion, race or culture.

"The ACT government is committed to ensuring all people are depicted in a respectful, empowering and dignified way, including people of different cultures, ages, genders and abilities," he said.

"We have seen some extremely offensive slogans and images portrayed on vehicles in other states, and we want to ensure that these will have no place on ACT roads."
