Every day on WA roads, drivers unknowingly break traffic laws that can lead to fines, demerit points, or worse – serious accidents. Whether you’ve been driving for decades or just earned your licence, some road rules remain consistently misunderstood or ignored.
Understanding these regulations isn’t just about avoiding penalties. It’s about protecting yourself, your passengers, and other road users from preventable harm. When accidents do occur due to rule violations, the legal and financial consequences extend far beyond the initial incident.
The Give Way to the Right Rule at Unmarked Intersections
Many WA drivers believe they have right of way simply because they arrived at an intersection first. This misconception causes countless collisions each year, particularly in suburban areas with unmarked crossroads.
The actual rule is straightforward: at an intersection without traffic lights or signs, you must give way to any vehicle approaching from your right. This applies regardless of who arrived first or which road appears larger.
The confusion often stems from overseas drivers applying different rules, or locals making assumptions based on road width. Neither factor matters under WA law. If a vehicle is on your right and you’re both entering the intersection, you must yield.
Common scenarios where this rule applies include:
- Residential streets without stop or give way signs
- Car park intersections and internal roads
- Private roads connecting to public streets
- T-intersections where you’re on the continuing road (you still give way to right-turning traffic from the terminating road)
The penalty for failing to give way: £400 fine and 3 demerit points. More importantly, these collisions frequently result in side-impact crashes with serious injuries. We’ve represented clients who suffered fractured ribs, head injuries, and psychological trauma from accidents at unmarked intersections where the at-fault driver simply didn’t understand this fundamental rule.
If you’re turning right at an unmarked intersection, you must give way to vehicles coming straight through from your right AND vehicles turning left from the road opposite you. The hierarchy of give way rules stacks quickly, which is why paying attention at every intersection – marked or not – remains critical.
Mobile Phone Use Extends Beyond Calls and Texts
WA’s mobile phone laws have expanded significantly, yet many drivers still believe they’re only breaking the rules if they’re actively talking or texting. This outdated understanding puts drivers at serious legal and safety risk.
The law prohibits holding or touching a mobile phone whilst driving. This includes when you’re stopped at red lights or stuck in traffic. Your vehicle must be parked with the engine off before you can legally handle your phone.
Prohibited actions include:
- Checking notifications or the time
- Changing music or podcasts
- Using navigation apps whilst holding the device
- Taking photos or videos
- Checking social media at traffic lights
- Holding your phone on speaker
The penalties are severe: £1,000 fine and 4 demerit points. During double demerit periods, this jumps to 8 points – enough to suspend most licences.
The only legal ways to use your phone whilst driving are through properly mounted cradles (where the phone can be operated without touching it) or via Bluetooth hands-free systems. Even then, you can still be charged with driving without due care if your phone use distracts you enough to cause dangerous driving.
Police now use detection cameras that can identify phone use from overhead gantries. These cameras capture clear images of drivers holding devices, making it nearly impossible to contest the infringement.
When motor vehicle accident claims involve phone use, the consequences multiply. Insurance companies scrutinise phone records, and courts take a dim view of drivers who caused collisions whilst illegally using devices. Compensation amounts can be reduced or denied entirely if you’re found at fault due to phone distraction.
Speed Limit Changes Apply Immediately at the Sign
A surprisingly common defence we hear after speed-related accidents is “I was still slowing down” or “I hadn’t reached the sign yet.” Neither excuse holds legal weight in WA.
Speed limits take effect exactly where the sign is positioned. There’s no grace distance to gradually reduce your speed. If the limit drops from 70km/h to 50km/h and you pass the sign doing 65km/h, you’re breaking the law.
This rule catches drivers particularly often in these situations:
- School zones activating during specified times
- Roadwork zones with temporary reduced limits
- Transitioning from rural highways to town centres
- Variable speed limit zones on freeways
The responsibility sits entirely with the driver to observe signs and adjust speed before reaching them. Police and speed cameras position themselves strategically after limit reductions, knowing many drivers fail to slow down in time.
Penalties scale with the speed exceeded:
- 1-9km/h over: £100 and 1 point
- 10-19km/h over: £300 and 3 points
- 20-29km/h over: £600 and 4 points
- 30km/h+ over: £1,200 and 7 points, plus possible licence suspension
Speed-related crashes typically result in more severe injuries than other collision types. The force of impact increases exponentially with speed. We’ve represented clients with catastrophic injuries – spinal damage, traumatic brain injuries, multiple fractures – from crashes where the at-fault driver was travelling just 20km/h over the limit.
When pursuing compensation for a car accident, establishing the other driver’s speed becomes crucial evidence. Motor vehicle accident claims that establish speed violations strengthen liability claims and can increase settlement values significantly.
Indicating Requirements Are More Extensive Than Most Drivers Realise
Turn signals aren’t optional courtesies – they’re legal requirements with specific rules about when and how long you must indicate. Yet indicator misuse remains one of the most common traffic violations on WA roads.
You must indicate for a minimum of five seconds before turning or changing lanes on roads with speed limits above 80km/h. On slower roads, you must give sufficient warning to other road users, which typically means at least three seconds.
Many drivers don’t realise these specific indicating requirements:
- Roundabouts: You must indicate left when exiting, even if you’re going straight through. Failure to indicate at roundabouts causes frequent collisions with cyclists and vehicles entering from other approaches.
- Merging lanes: You must indicate when your lane ends and you’re merging into continuing traffic, even though you don’t technically have a choice about merging.
- Leaving a parked position: You must indicate for at least five seconds before pulling out from the kerb.
- Changing lanes in heavy traffic: The indicator requirement doesn’t disappear just because traffic is slow. You still need to signal lane changes at 20km/h.
The penalty for failing to indicate: £150 fine and 2 demerit points.
The real cost comes in accident liability. When motorcycle accident compensation claims involve a vehicle that changed lanes or turned without indicating, the failure to signal typically establishes clear fault. Motorcyclists are particularly vulnerable to drivers who don’t indicate, as they have less time to react and fewer protective options.
One case involved a driver who changed lanes on the freeway without indicating and collided with a motorcycle in their blind spot. The motorcyclist suffered serious leg injuries requiring multiple surgeries. The driver’s failure to indicate for the required five seconds meant they bore full liability for the collision, despite claiming they “didn’t see” the motorcycle.
The Blood Alcohol Limit Isn’t a Target
WA operates on a 0.05% blood alcohol limit for full licence holders, but this figure creates a dangerous misconception that drivers can safely consume alcohol up to this threshold.
In reality, impairment begins well below the legal limit. Studies show that at 0.02%, drivers experience reduced visual function and impaired judgment. At 0.05%, reaction times slow noticeably and risk-taking behaviour increases.
The legal limit represents the point where the law steps in and declares driving illegal – not the point where alcohol becomes safe. Responsible driving often means consuming no alcohol at all before driving.
Professional drivers face stricter limits: 0.02% for bus and taxi drivers, 0.00% for truck drivers. These lower limits reflect the real dangers of alcohol impairment, particularly when lives beyond the driver’s own are at stake.
Provisional licence holders face 0.00% limits. Young drivers with less experience simply cannot afford alcohol impairment whilst developing driving skills.
What Happens After a Road Rule Violation Causes an Accident
When accidents result from traffic law violations, multiple legal systems intersect. Understanding your rights ensures you receive appropriate compensation.
The Insurance Commission of Western Australia (ICWA) manages the Compulsory Third Party (CTP) insurance system. If another driver caused your injuries, their CTP insurance provides compensation for your medical expenses, lost wages, rehabilitation costs, and pain and suffering.
You’re eligible for ICWA compensation if:
- You’re injured by another vehicle in a traffic incident
- The other vehicle was insured (or identifiable)
- You weren’t driving an unregistered vehicle or involved in illegal racing
You might be ineligible if:
- You were partially at fault (though your compensation reduces proportionally)
- The other driver was uninsured for vehicle damage
- The collision occurred on private property
The CTP system covers medical expenses, lost wages, rehabilitation costs, and pain and suffering. For catastrophic injuries resulting in permanent impairment, compensation can extend to future care needs, home modifications, and lifetime income loss.
Time limits apply strictly. You generally have three years from the accident date to commence legal proceedings, though you should contact us much sooner to preserve evidence and protect your rights.
Evidence collection becomes crucial in establishing the other driver’s road rule violation. This includes:
- Police accident reports
- Witness statements
- Dash cam footage
- Mobile phone records (if distraction is suspected)
- Vehicle damage patterns
- Intersection or roadway photos
When road rule breaches cause workplace injuries – such as delivery drivers, truck operators, or anyone injured whilst working – you may have both a workers’ compensation claim and a motor vehicle injury claim. These run concurrently and require careful coordination to maximise your total compensation.
What to Do Immediately After an Accident Involving a Road Rule Breach
The moments following a collision determine both your safety and the strength of any future legal claim. Even if you’re shaken or injured, certain steps protect your interests.
Immediate priorities:
- Check for injuries and call 000 if anyone needs medical attention
- Move to safety if possible, but don’t leave the scene
- Exchange details with all involved drivers – names, addresses, licence numbers, registration, and insurance information
- Document everything – take photos of vehicle damage, road conditions, traffic signs, and the overall scene
- Identify witnesses and get their contact information
- Report to police if there are injuries, significant damage, or if the other driver leaves the scene
Never admit fault at the scene. Even apologising can be interpreted as accepting liability. Stick to factual statements when speaking with police or other drivers.
Seek medical assessment even for seemingly minor injuries. Soft tissue damage, whiplash, and concussion symptoms often emerge hours or days after the initial trauma. Medical records from immediately after the accident provide crucial evidence linking your injuries to the collision.
For cycle accident claims or motorcycle incidents, the injury severity often requires immediate hospitalisation. Ensure someone photographs your damaged bicycle or motorcycle before it’s moved, as this evidence proves impact force and collision dynamics.
The Long-Term Impact of Road Rule Violations
Road traffic injuries ripple far beyond the initial collision. Physical injuries may heal, but the financial, emotional, and practical consequences can persist for years.
Common long-term effects include:
- Chronic pain requiring ongoing treatment
- Psychological trauma including anxiety, depression, and PTSD
- Reduced earning capacity or inability to return to previous employment
- Relationship strain from personality changes or care dependencies
- Loss of independence and lifestyle enjoyment
When injuries prevent you from working, you may qualify for a Total and Permanent Disability claim through your superannuation in addition to motor vehicle injury compensation. These claims require medical evidence that your injuries permanently prevent you from working in any capacity suited to your education, training, or experience.
The financial pressure intensifies quickly. Medical bills accumulate, income stops, and daily living costs continue. Early legal advice ensures you understand all available compensation sources and don’t accept inadequate settlement offers before understanding the full extent of your injuries.
Insurance companies employ experienced assessors and lawyers whose job involves minimising claim payments. Without proper legal representation, injured people routinely accept settlements that fail to cover their actual losses or future needs.
Why Legal Expertise Matters in Road Rule Violation Cases
Road traffic law intersects with personal injury law, insurance law, and sometimes criminal law. Successfully navigating these overlapping systems requires specific expertise and experience.
We handle the legal complexity whilst you focus on recovery. This includes:
- Investigating the accident and gathering evidence
- Obtaining police reports and witness statements
- Coordinating medical assessments and treatment
- Calculating full compensation entitlements
- Negotiating with insurance companies
- Commencing court proceedings if necessary
Our approach prioritises your recovery and financial security. We operate on a no-win, no-fee basis for most personal injury claims, meaning you don’t pay legal fees unless we secure compensation for you.
Many clients initially hesitate to seek legal help, worried about costs or complexity. The reality is that early legal involvement typically increases final compensation amounts substantially – far exceeding any legal costs. Insurance companies offer higher settlements when they know you have experienced representation.
