Failing to come to a complete stop at a stop sign is the most common road rule Queensland drivers ignore.
More than 9200 drivers in the 12 months up until last November were fined in the state for disobeying stop signs.
Queensland's peak motoring body, the RACQ, says more than 3000 Brisbane drivers alone were caught flouting one of the most fundamental road rules.
"It should be one of the easiest rules to understand," RACQ spokesperson Lauren Ritchie said.
"Stop signs mean you must come to a fully controlled stop behind the line before you take off again. It's not rocket science.
"To flout the law like this is really a dumb behaviour."
Disobeying a stop sign topped the list of the five rules drivers ignore on Queensland roads, which the RACQ have released on Thursday.
Other basic rules that are being disobeyed are "no right turn" signs, following other vehicles too closely, driving at night without lights and driving with L plates when you're not a learner.
