The latest flooding has caused major damage to the Warrego Highway in southern Queensland.
Residents in Dalby on the western Darling Downs are still cleaning up after the weekend floods but the recent wet weather has also caused significant damage along the highway.
RACQ spokesman Greg Miszkowycz says he is not surprised.
"In terms of its inferior soil conditions in the black soil areas of the Darling Downs it's very difficult [to] both construct and maintain a suitable road surface in those highly expansive clay territories," he said.
He says governments must provide enough money to build and maintain a suitable road surface.
"Certainly a lot of those areas that were damaged previously and have received flood recovery money have been strengthened and rehabilitated," he said.
Western Downs Mayor Ray Brown is urging local motorists to take care.
"Some of these potholes are quite severe," he said.
"Our staff are trying to get to them as quick as possible. Just keep in mind be patient and give yourself additional time to get to your destinations.
"Some of them about the size of vehicles where they've blown out and these are, particularly to small cars, very concerning.
"We just ask people to take their time and be cautious."
