Your car’s dashboard symbols and warning lights aren’t much help if you ignore or can’t understand them. These are the most common – and most important – car symbols and warnings to know.
How to pick the best steering wheel lock for your car

Car steering wheel locks can help deter thieves and provide an extra layer of security. Here’s how to choose the best steering lock for your vehicle.
In 2024 Victoria recorded its highest level of car theft in more than two decades, with 25,153 car thefts and 3,769 attempted car thefts, according to the Crime Statistics Agency.
With those numbers representing a 41 per cent increase on the year prior, many Victorians may be wondering what steps they can take to further secure their vehicles.
Like trailer anti-theft devices, car steering wheel locks are a visible and accessible security solution. These locks work as a deterrent to would-be thieves on the lookout for easy targets.
RACV Head of Policy James Williams says while steering locks are simple they can still be effective.
“Using a visible deterrent like a steering wheel lock helps to put off an opportunistic thief from attempting to steal your vehicle," he says. “It adds an extra layer of complexity to breaking into and starting a vehicle, but is only one part of the action you can take to reduce the chance of your vehicle being a target.
“Parking in a well-lit area, fitting a vehicle tracker with visible signage, and fitting an OBD lock are also great ways to make thieves think twice.”
Do car steering wheel locks help prevent theft?
If a thief is determined to steal your car then a steering lock probably won’t stop them. Removing high-value items like wallets, electronics and jewellery from your car before leaving it can further help deter thieves from targeting your vehicle.
How do car steering wheel locks work?
Car steering locks work by preventing the steering wheel from being turned. The ignition can still be turned on, but it will be almost impossible to steer in any direction unless the lock is removed.
Some steering wheel locks come with alarms and most are locked or unlocked using a key. Keep the key and any spares separate to your car unless you are operating it. A steering wheel lock is no good if you’ve left the key in your centre console or glove box. Store the key somewhere safe and memorable, as you may need to break the lock or contact a locksmith if you lose it.
When not in use, consider storing the steering wheel lock in a secure place inside the boot to prevent it rolling around and causing damage to your car's interior.

What is the best type of car steering lock?
There are multiple types of steering wheel lock available in Australia. They differ in how they attach to and immobilise the wheel. Where possible, opt for a lock in a bright colour – they might look garish, but they immediately let thieves know to avoid your vehicle.
Importantly, steering wheel locks are not one-size-fits-all. Research what lock would suit your vehicle before purchasing – many auto retailers can help you determine which type of lock will fit your car.
Bar locks
Probably the most common type of steering lock available, bar locks are comprised of either a single or double bar that clamps onto the steering wheel. Most can be adjusted to fit your specific steering wheel.
T-bar locks
Similar to bar locks, T-bar locks clamp onto your steering wheel in the 12 o’clock position and extend over the dashboard, preventing wheel movement.
Cord locks
Cord steering locks are similar to a corded bike lock, wrapping around the steering wheel before attaching to an anchor point in the car (often the seatbelt clasp). These locks are easily stored and engaged, but can also be easily cut by thieves.
Brake/Pedal locks
Brake or pedal locks are similar to T-bar locks. But instead of clamping to the top of the steering wheel, they typically clamp or hook onto the bottom of the wheel, in the 6 o’clock position. A metal bar then extends out and latches to the brake pedal. This prevents both the steering wheel and brake pedal from being used. They can be tricky to engage for people with mobility limitations.
Full cover locks
Full cover locks cover the entire steering wheel and lock it off. Because of this, they tend to be heavy and take up a large amount of space in your vehicle.
Tips for choosing the best steering wheel lock for you
When purchasing a steering wheel lock consider:
Security
The lock should be sturdy enough to deter all but the most determined thieves.
Your vehicle
Not all steering wheel locks will fit all makes and models of car.
Ease of use
Can you install and uninstall the lock easily?
Size and weight of the lock
Larger and heavier locks may be harder for thieves to crack but are no good if it’s too heavy for you to safely use or takes up too much space in your car.
Appearance
Bright colours are best to immediately alert thieves that it’s not worth breaking into your car.
