When should you switch on?
After sunset
By law, headlights should be used from dusk until dawn, but as soon as natural light dips, it's time to turn them onIn tunnels or covered areas: Even during daylight hours, turning on your lights in tunnels ensures your vehicle is visible.
Hazardous weather/low visibility
When the weather takes a turn for the worse, like during heavy rain or fog, it’s crucial to use your headlights to improve visibility. The rules don’t specify which type of headlights to use, so choose based on the conditions – low beam, high beam, or fog lights as needed. The goal is to make sure you’re visible to others as much as you can see them.
High beam vs. low beam
Understanding when to use high beam and low beam headlights can be a bit confusing, but here’s a simple guide:
-
Low beam: Use these when driving in well-lit areas or when there’s oncoming traffic. They’re designed to illuminate the road ahead without blinding other drivers.
-
High beam: These are great for dark, rural roads where you need extra visibility. However, you must switch to low beam when you’re within 200 metres of another vehicle, whether it’s coming towards you or you’re following it
Use them only when needed, as they can hinder visibility for pedestrians and cyclists.
Fog lights
Fog lights are great in fog, heavy rain, or mist, but avoid using them in clear weather - they can dazzle other drivers and may lead to fines.
Daytime running lights (DRLs)
Modern vehicles often feature DRLs. While helpful for visibility, remember they don’t replace regular headlights at night or in low-visibility conditions.
Interior lights
Ever wondered if it’s okay to drive with your interior light on at night? In WA, there are no penalties for this. However, it’s best to avoid it as it can limit your vision of the road. Use the interior light only when you’re safely pulled over.
Common mistakes to avoid
-
Waiting too long: Many drivers hesitate to use headlights during twilight, which can create unnecessary risks. It’s better to switch them on earlier rather than later.
-
Relying solely on parking lights: Parking lights are insufficient for driving and are designed for stationary vehicles.
