One of the most common accessories used by off-road enthusiasts could attract a hefty fine from authorities.

The Queensland Police Service (QPS) has issued a warning to drivers fitting reflective window coverings, stating the modification may be in breach of road laws.

Most commonly seen on off-road SUVs to help deflect the sun’s rays from the rear cargo area – which is often home to a 12-volt refrigerator – the soft, shiny panels also block the view of traffic from the rear and side.

“Not complying with this road rule attracts a $389 fine and risks the safety of vulnerable road users such as pedestrians and bicycle/scooter riders by drastically reducing vision,” a statement from the QPS reads.

However, some have questioned the warning, claiming the accessories are allowed if fitted to the rear windscreen and the cargo area windows located behind the C-pillars – provided they are secured and are made from non-reflective material.

According to one online post, Queensland regulations don’t require the driver to have visibility out the rear window if the vehicle has compliant external side mirrors, citing the fact that many utes are legally fitted with canopies that block the rear window – including the police’s own ‘paddy wagons’.
