Drivers are being warned to not put their arm of their car window to wave or they could be hit with a hefty fine.
The little known road rule could cost motorists a fine of $337 and a loss of three demerit points if they’re caught doing the simple act, according to Budget Direct.
The insurer warned both passengers and drivers face the same penalties if caught engaging in the friendly gesture.
“Even winding down the window and stretching your arm outside to cool down could also get you in trouble,” the insurer stated.
“According to all state and territories’ driving regulations, it is illegal for any part of your body to be outside a moving vehicle at any time.”
The insurer encouraged drivers bid farewell by waving inside the vehicle to avoid the fine.
However, if the driver is using their arm to signal they are turning right, slowing down or stopping, then they won’t be fined by authorities.
Budget Direct also shared insight into some other little known road rules some drivers need to pay attention to.
It’s illegal in all states and territories to drive with a dog or pet on your lap, according to the insurer.
Drivers caught with their precious animals on their lap while driving could face demerit point reduction.
“Not only is this dangerous to yourself and other drivers as the unrestrained dog could obstruct your view or interfere with your driving, but should you lose control, your pet could be seriously harmed from an impact,” the insurer warned.
“So even if your pooch is the size of a tea cup, just don’t risk it.”
Another road rule to be aware of is for those drivers who like to use their car horn on the regular.
“It is actually illegal to use your horn across all of Australia unless you are warning other drivers that your vehicle is approaching, trying to get animals off the road, or, as part of an antitheft or alcohol interlock device,” the insurer stated.
“In all other circumstances you could be breaking the law.”
