The survey involving 13,000 licence holders in 23 countries comes as the RAC Foundation warns Britons driving abroad this summer to take care.
And UK drivers in Spain and Portugal were three times more likely to be in a fatal accident.
The survey of motorists' attitudes was released by the RAC and conducted for Europe-wide body Responsible Young Drivers.

According to the RAC Foundation, three million British motorists head to the continent in their cars every year, while many more hire a car on arrival. In Europe as a whole, 57.3% of holiday trips are made by car.
RAC Foundation executive director Edmund King urged UK drivers to find out about local rules and regulations.
"High holiday spirits and poor local knowledge can turn a drive to the beach into a trip to A&E," Mr King said.
"British motorists driving abroad need to expect the unexpected at all times if they want to bring home holiday photos rather than X-rays."
Separately, the AA is warning motorists heading for popular UK tourist destinations to take care in "deadly" lay-bys.
Nearly two-thirds of fatal accidents involving stopped vehicles on a dual carriageway happen in a lay-by, a study from the AA Motoring Trust found.
More than half the vehicles hit are lorries and in the past year at least six people have died in lay-by crashes in the UK, the trust said.
It added that drivers should stay out of lay-bys that are not separated from the main road by a kerbed island.
The trust's study, co-funded by the Highways Agency, surveyed lay-bys along the A303 and the A34, two busy holiday routes leading to south and south-west England.
