When you’re driving at night in the rain, there’s one thing you rely on more than headlights or wipers: clear, visible road markings. Without them, confusion and danger take over. Cars drift. Passengers and pedestrians are at risk. Technology like autonomous vehicles can’t read the road.
At Dolphin Line Marking, we believe road markings are more than just paint on asphalt. They’re a safety systems for human drivers and for the future of machine vision.
But not all markings are created equal. Let’s break down why the type of line matters, how visibility changes in wet and glare conditions, and why Dolphin uses professional techniques and materials to keep Australia’s roads, carparks, and workspaces safe.
Flat Lines vs Structured Lines: What’s the Difference?
Not all road markings work the same.
- Flat Road Markings (Type I)
These are thin, painted lines that sit flat on the road surface. They’re quick to apply and cost-effective. But in rain or glare, water pools on top. The result? Light reflects off the water, and the line almost disappears. For human drivers and vehicle cameras, flat lines can become nearly invisible. - Structured Road Markings (Type II)
These are raised or textured markings, usually made from thermoplastic or cold-applied plastic. They’re embedded with premium glass beads and designed with a profile that helps water drain away. That means they stay bright and reflective even in wet or foggy conditions. And they’re easier for autonomous vehicle sensors like LiDAR (Light Detection and Ranging) to detect.
👉 The bottom line: Flat lines are fine for dry, low-traffic areas. But for critical safety zones-pedestrian crossings, highways, busy carparks—structured markings win every time.
The Challenge of Wet Nights and Glare
Many of us have experienced it: you’re driving on a rainy night, and suddenly the road ahead looks like a mirror. Headlights bounce back. Lines vanish.
That’s both alarming and dangerous.
- Flat lines: In wet conditions, visibility can drop to zero. Cameras on vehicles also struggle, as the contrast between line and asphalt disappears.
- Structured lines: Thanks to their raised profile and premium beads, they keep reflecting light, guiding both humans and machine vision systems.
Even so, glare stays a challenge. Studies show that glare can reduce visibility almost to nothing for both line types. This is where technology like LiDAR sensors comes in as its able to cut through glare where cameras fail. But LiDAR alone isn’t perfect; it works best when combined with cameras and with high-quality structured markings.
Why It Matters for Drivers and Autonomous Vehicles
Today’s roads aren’t just for people they’re also for driverless machines. Advanced Driver Assistance Systems (ADAS) and semi-automated vehicles rely on road line markings to know where to steer.
If markings fade or vanish under glare or water, vehicles can “go blind.” That’s why high retro reflectivity and structured profiles are becoming the global standard for safer roads.
For human drivers, the benefits are immediate:
✅ Less strain at night
✅ Safer navigation in rain and fog
✅ Reduced accident risk
For machine drivers (autonomous systems):
✅ Reliable Lane detection
✅ Faster recovery after rain
✅ Cleaner data for steering algorithms
It’s a win-win for now and for the future.
Beyond Roads: Carparks, Warehouses, and Worksites
At Dolphin Line Marking, we know it’s not just highways that need safe lines.
- Carparks: Clear arrows, disabled parking symbols, and bay numbers keep traffic flowing and prevent fender-benders.
- Warehouses & Workshops: Safety zones, walkways, and hazard stencils reduce workplace accidents.
- Cycle Lanes: Structured, high-contrast lines protect vulnerable riders in all weather.
Add in fixtures like bollards, wheel-stops, convex mirrors, and safety signs, and Dolphin becomes your one-stop safety partner.
The Future: Structured V and Glow Roads
Looking ahead, Australia is testing new innovations in road markings:
- Structured V Lines (2025): V-shaped profiles that reduce noise and vibration while staying highly visible for both humans and machines.
- Glow Roads: Photoluminescent markings that shine at night without electricity, making unlit roads safer.
Dolphin Line Marking stays at the cutting edge, following Austroads standards and new technologies to ensure our clients always get markings that meet today’s and tomorrow’s demands.

Educational Takeaway: The Real Cost of Faded Lines
Think line marking is just a “tick-the-box” job? Think again.
Poor or faded markings cause:
❌ Increased accidents at crossings and carparks
❌ Confusion in traffic flow
❌ Workplace safety hazards
❌ Higher long-term costs due to frequent repainting
On the other hand, professional, structured markings provide:
✅ Durability
✅ Visibility in all conditions
✅ Compliance with safety standards
✅ Peace of mind for councils, businesses, and drivers
