Dimension Offences for Truck Drivers in Australia:
What you need to know
In Australia, truck drivers are required to follow strict regulations regarding the dimensions of their vehicles, including height, width, and length limits. When a vehicle exceeds these limits, it can result in what’s known as a “dimension offence.” These types of offences carry significant penalties, which can range from fines to more serious consequences like court appearances and vehicle impoundment. As a truck driver, it’s crucial to understand the regulations and know what to do if you’re pulled over for a dimension-related issue.
At Big Rig Law, we specialise in defending truck drivers facing dimension offences. We know how these types of infractions can disrupt your work and cause unnecessary stress, which is why we’re here to help you navigate the legal process. Whether it’s an issue with your vehicle’s height, width, or length, our expert legal team is here to support you and fight for the best outcome.

What Are Dimension Offences?
A dimension offence occurs when a truck exceeds the legal size limits set by Australian road authorities.
These limits are put in place to ensure the safety of both the truck driver and other road users. Overly large vehicles can pose risks, particularly when driving through tunnels, under bridges, or navigating narrow roads. The most common dimension limits (when not operating under a permit) include:
- Height limits: Most trucks are restricted to a maximum height of 4.3 metres, though this can vary slightly depending on the load and the route.
- Width limits: The standard width limit for vehicles is 2.5 metres.
- Length limits: The legal length limit for a combination truck is 19 metres, though special permits can allow for longer combinations.
Exceeding these limits can result in a dimension offence, leading to fines and, in more serious cases, the vehicle being taken off the road until it is brought back within legal limits.
Why Do Dimension Offences Happen?
- Incorrect loading: If the load shifts or isn't properly measured, the overall dimensions of the truck can change without the driver realising.
- Inaccurate equipment: Sometimes the tools used to measure the truck and its load aren’t entirely accurate, leading to miscalculations.
- Permits and route planning: Drivers may not be aware that certain routes have different dimension limits or require special permits, resulting in accidental breaches.
These offences can be particularly frustrating for drivers, especially if they occur due to circumstances beyond their control. That’s where Big Rig Law comes in. We understand the challenges you face on the road and can help defend against massive fines and penalties.
What to Do If You’re Pulled Over for a Dimension Offence
1. Stay Calm and Cooperative
When pulled over, it’s important to stay calm and cooperate with the enforcement officer. Provide your paperwork, including any permits, and listen carefully to what the officer is saying. Getting defensive or argumentative will only escalate the situation.
2. Ask for Specifics
If the officer accuses you of a dimension offence, ask them to explain the specifics. What part of the truck or load is in violation? How was the measurement taken? Asking for this information will help you understand the situation better and prepare for any legal defence.
3. Take Photos and Measurements
4. Request a Re-Measurement
5. Contact Big Rig Law

Penalties for Dimension Offences
The penalties for dimension offences in Australia vary depending on how much the truck exceeds the legal limits. Penalties for companies are 5 times more than for an individual. Here’s a breakdown of the potential penalties:
- Minor Offences: For smaller breaches, you may receive a fine that starts at a few hundred dollars. These are typically resolved quickly with the vehicle being brought back into compliance.
- Substantial Offences: More substantial breaches will result in higher fines, often reaching into the thousands of dollars. In some cases, the truck may need to be modified or unloaded to meet legal limits before continuing the journey.
- Severe Offences: In cases where the vehicle is significantly over the legal dimensions, the penalties are much more severe. A sever risk breach automatically results in a court appearance notice.
Can You Dispute a Dimension Offence?
Yes, you can dispute a dimension offence, especially if there’s reason to believe the measurement was inaccurate or if the offence was unintentional and you would like to explain the circumstances to the court. Big Rig Law has in-depth knowledge of dimension regulations. We will carefully review the circumstances surrounding your offence, check the measurement procedures, and look for any possible defences that could help reduce or dismiss the fine.
