A road safety group wants to see tourist drivers' understanding of the road rules checked before they get behind the wheel.
This comes after a Chinese national was killed in a head on collision after driving on the wrong side of the road.
Brake's Caroline Perry says more needs to be done to make sure they know all the information.
"Keeping on the left-hand side of the road, sticking to the speed limit or driving below it, keeping to the conditions," she says.
"Also not driving tired - if you're come over on a long flight making sure you have a good break before you start driving, and also regular breaks when you're on your journey."
She says rental vehicles companies should check they know the rules and how to drive the vehicle before they're handed the keys.
