Received an NHVR infringement notice? Under investigation for a fatigue breach? Facing Court over work and rest hour allegations?
If so, you're in the right place.
Fatigue offences are among the most heavily enforced offences under the Heavy Vehicle National Law (HVNL). A fatigue breach can result in significant fines, demerit points, court proceedings, regulatory investigations, business disruption, and serious Chain of Responsibility (CoR) consequences.
For transport operators, fatigue allegations can affect far more than a single driver. The NHVR can investigate schedulers, operators, directors, employers, consignors and other parties in the transport chain.

What Is a Heavy Vehicle Fatigue Offence?
Under the Heavy Vehicle National Law, drivers of fatigue-regulated heavy vehicles must comply with strict work and rest requirements designed to reduce fatigue-related crashes. The NHVR considers fatigue one of the most significant safety risks in the transport industry.
A fatigue offence generally occurs when a driver:
- Works longer than permitted
- Fails to take required rest breaks
- Fails to take required night rest breaks
- Exceeds maximum work limits
- Fails to comply with fatigue accreditation requirement
- Fails to maintain accurate fatigue records
- Makes false work diary entries
- Drives while impaired by fatigue
- Causes or permits another person to breach fatigue laws
The law applies to fatigue-regulated heavy vehicles operating under:
- Standard Hours
- Basic Fatigue Management (BFM)
- Advanced Fatigue Management (AFM)
Why Fatigue Offences Are Taken So Seriously
The NHVR treats fatigue breaches differently from many other traffic offences.
Unlike ordinary speeding or parking offences, fatigue offences are considered safety-critical because fatigue significantly increases the likelihood of:
- Fatal crashes
- Serious injury collisions
- Loss of vehicle control
- Driver error
- Reduced reaction times
- Poor decision making
The Four Categories of Fatigue Breaches
Under the HVNL, fatigue offences are classified into four risk categories.
1. Minor Risk Breach
The lowest category.
A minor breach usually occurs where work limits are exceeded or rest requirements are missed by a relatively small amount.
Even though it is called “minor”, it still remains an offence and can still attract significant penalties.
2. Substantial Risk Breach
A more serious breach involving greater departures from legal work and rest requirements.
The NHVR may regard these offences as evidence of poor compliance systems or poor fatigue management.
3. Severe Risk Breach
A severe risk breach occurs when fatigue requirements are exceeded to a level creating a substantial safety risk.
These matters frequently proceed to Court.
Severe risk breaches can attract:
- Large fines
- Demerit points
- Court proceedings
- Regulatory scrutiny
4. Critical Risk Breach
The most serious fatigue category available under the HVNL. Fatigue is the only area of the HVNL with a “critical risk” category.
Critical risk breaches generally involve:
- Significant excess work hours
- Serious rest deficiencies
- Extreme fatigue exposure
- High safety risks
This occurs when a driver works longer than permitted under:
- Standard Hours
- BFM Hours
- AFM Hours
Examples include:
- Exceeding 5.5-hour limits
- Exceeding 8-hour limits
- Exceeding 11-hour limits
- Exceeding 12-hour daily limits
- Exceeding 7-day limits
- Exceeding 14-day limits
- Exceeding 28-day limits
The seriousness depends on how far the limit was exceeded.
One of the most serious fatigue-related allegations. These can significantly increase the likelihood of court proceedings. Examples include:
- Altering records
- Recording breaks that never occurred
- Recording work as rest
- Concealing actual driving hours
These offences are among the most common fatigue prosecutions. Examples include:
- Missing 15-minute breaks
- Missing 30-minute breaks
- Taking breaks too late
- Failing to obtain required stationary rest
Certain fatigue schemes require specific night rest breaks. Depending on how serious the breach is, failing to get these rest periods can result in:
- Minor risk breaches
- Substantial risk breaches
- Severe risk breaches
- Critical risk breaches
The HVNL places a clear obligation on drivers not to drive a fatigue-regulated heavy vehicle while fatigued.
A driver can be compliant with work diary requirements but still commit an offence if they continue driving while fatigued.
Drivers required to keep a National Driver Work Diary may commit offences by:
- Not carrying a work diary
- Not producing a work diary
- Not completing entries correctly
Businesses may commit offences by failing to:
- Retain records
- Store work diary information
- Maintain fatigue management documents
- Produce records when required
BFM operators have additional obligations. Common offences include:
- Exceeding BFM work limits
- Failing to comply with accreditation requirements
- Failing to maintain fatigue management systems
- Exceeding long/night work limits
AFM operators must comply with:
- Approved AFM systems
- Risk controls
- Approved operating conditions
- Interlock consequences
Chain of Responsibility (CoR) and Fatigue
One of the biggest mistakes transport businesses make is assuming fatigue laws only apply to drivers. They don’t. Under Chain of Responsibility laws, the NHVR can investigate:
- Employers
- Directors
- Schedulers
- Operators
- Prime contractors
- Consignors
- Consignees
- Loading managers
Anyone whose actions, demands, schedules or business practices contributed to a fatigue breach may face enforcement action.
Can You Defend a Fatigue Charge?

If you’re facing a fatigue offence, don’t wait. The earlier you act, the more opportunities there may be to protect your licence, your livelihood and your business.
Frequently Asked Questions
A critical risk fatigue breach is generally the highest fatigue risk category under the HVNL.
Yes. Chain of Responsibility laws can expose businesses, directors and schedulers to liability.
Besides driver penalties, fatigue offences can harm your business. The NHVR can suspend your authorisations or issue prohibition notices. Insurance premiums may rise. One crash or fine can trigger a Chain of Responsibility investigation, risking corporate penalties. We’ve helped many owner-drivers and SMEs avoid ruin by minimizing fines and fighting unreasonable charges. If your business depends on your licence, get legal advice fast.
A: Yes – by strict compliance. Use Electronic Work Diaries correctly, take your mandated rest breaks, and carry your logbook at all times. Plan routes realistically.

If police or NHVR visited you, know that we have the evidence solutions and arguments to help. Prevention is best, but if you find yourself in trouble, reach out immediately.
