And to make sure it's unforgettable for all the right reasons, road safety experts say there's a few things school leavers can incorporate into their summer plans if they're getting ready to hit the road over the holiday period.

Road Safety Education (RSE) general manager Brooke O'Donnell said risks for young drivers have increased with more cars on the road and a wet summer forecast ahead.

"Many young people will be driving on roads they've never driven before and after a year of heavy rain, the condition of many of those roads, particularly in regional areas, may be poor," she said.

"The wonderful thing about a road trip is that it's meant to be a holiday so we need remember that; slow down and take your time."

The Bureau of Meteorology has forecast above-average rainfall for the coming months in Australia's third consecutive La Nina season.

RSE's guide to driving in the wet warns of 'aquaplaning,' when a layer of water builds up between car tyres and the road surface and the tyres lose grip. That risk increases when it's raining, and can be felt as loose steering, a revving engine or the back wheels drifting.

The advice is that if drivers start to aquaplane, they should brake gently.

Ms O'Donnell said young drivers can go over the road trip checklist to prepare, which includes planning the route and best rest stops along the way, checking basics of the car, from tyres and oil to brake lights, and laying down trip ground rules with any passengers.

"We recommend that young people keep passengers to a minimum, as they can be distracting, especially for someone with little experience on long trips," Ms O'Donnell said.

"If you are taking passengers, include them in the planning and set the rules of the car together, agreeing ahead of time that everyone will take responsibility for minimising distractions and ensuring everyone arrives safely to the destination."

And it's not just youngsters that can benefit from planning ahead.

Sleep expert Olivia Arezollo said it was critical all drivers were getting enough sleep before hitting the road.

"Even if it feels like you'll be okay with a coffee or Red Bull, scientifically, after 17 hours of being awake you have the driving capacity of someone with a [blood alcohol concentration] of 0.05 per cent; technically drunk," she said.

According to the Victorian Transport Accident Commission, 20 per cent of all road accidents involve fatigue and 20 to 30 per cent of all deaths or severe road injuries are caused by sleepiness.

Ms Arezollo advised drivers to take short breaks every two hours on their journey and include a nap, getting some sunlight and a walk.

"It will help you arrive alive," she said.

"To make the most of your break, it's helpful to know what will keep you energised. This includes sun exposure, to ensure your melatonin, the sleepy hormone, is suppressed, and plenty of movement."

Ms Arezollo recently released a 10-minute guided meditation for drivers which can be found here.
