"Our online real-time highway information service will tell you whether there are any travel warnings or closures ahead. You can also check out the cameras to see how traffic is moving in and out of the city."

Top tips for a safe and enjoyable Queen's Birthday trip
- Plan ahead. Get your vehicle checked before you head out, plan to avoid peak traffic.
- Drive to the conditions. This isn't just about weather conditions — it's about the road you're on, the traffic, your vehicle and load, your speed, your following distance, and adjusting your driving for wet and windy conditions.
- Watch out for fatigue. Long trips are tiring and fatigue can be deadly behind the wheel.
- Keep your cool. Holiday driving can be frustrating with busy roads, and restless kids in the car. Be courteous and patient while on the roads.
- Buckle up. Don't let your family holiday be marred by tragedy simply because someone didn't buckle up.
- Don't drink and drive. The alcohol limit for adult drivers is now lower, and your judgement and reaction times begin to deteriorate after even one drink.
