Obey speed limits and drive to the road conditions;
If you are going to drink, leave your car/vehicle at home and organise a ride;
Don't tailgate, especially in wet or rainy conditions - leave a safe distance between your vehicle and the vehicle in front;
Don't talk or text on a mobile phone whilst driving;
Wear your seat-belt and ensure everyone else in the vehicle is also 'buckled up';
If you are stuck in holiday traffic, remain patient
Don't try to make up for lost time by exceeding the speed limit - it’s better to arrive at your destination late, rather than not at all;
Make sure you are well-rested before commencing your road trip;
At the first sign of fatigue, pull over (where safe and legal) and have a break;
Look out for driver-reviver stations and take advantage of their facilities.
