Drivers who break the road rules are being blamed for adding to congestion problems

In just a few days on Brisbane roads, one frustrated truck driver collects dash cam footage of drivers doing the wrong thing time and time again. Key points: UQ traffic engineer Adam Pekol says poor merging is one of many bad driving habits that add to traffic congestion On motorways it is illegal to remain in the right-hand lane after overtaking Last year, 771 Queenslanders were fined and lost a demerit point for illegally staying in the right-hand lane The most common mistake captured on camera was cars crossing solid lines to merge onto motorways — an illegal manoeuvre that could cop a $106 fine, according to Queensland police. Traffic engineer and University of Queensland associate professor Adam Pekol said poor merging was one of the many driver habits contributing to congestion problems on major arterials in the south-east region. 'Keep left unless overtaking' Other common mistakes include remaining in the right lane on multi-lane roads with speed zones of 90 kilometres per hour or more, or if the road has a "keep left unless overtaking" sign. Transport and Main Roads confirm it is illegal to use the right lane in these circumstances unless you are: overtaking turning right making a U-turn avoiding an obstruction driving in congested traffic, or using a special purpose lane you are allowed to be in In the first four months of this year, 184 people were fined in Brisbane and the surrounding south-east region for driving in the right lane or disobeying the "keep left unless overtaking" sign without a reasonable excuse.
