More than half of Britons would ignore Foreign Office (FO) advice about unsafe destinations, according to a survey.
Nearly all (91%) were unaware for which countries the FO had issued traveller warnings, the poll by travel agent sunshine.co.uk found.
And 75% said they would not check the FO website before travelling to see if their destination carried a warning.
A total of 1,962 British adults took part in the survey.
As many as 53% said that if they had made up their mind to travel to a destination and the FO advised against going there, they would ignore the advice and travel anyway.
Those who heeded travel warnings and would cancel or delay travel said that "violent incidents and protests" at their destination would be most likely to deter them.
Warnings of "severe weather and natural disaster" were also likely to keep people at home.
Sunshine.co.uk managing director Chris Clarkson said: "The FO issues travel warnings for a reason. Britons wishing to remain safe and enjoy a hassle-free trip overseas should always check the FO website for advice and base their travel plans around what they find.
"It's not often that popular holiday resorts will have warnings issued against travel there, but it's always worth checking just in case."
He went on: "I was shocked to see that many Britons don't bother to check advice that's been issued, as it should be part and parcel of the holiday bookings process, especially if you're planning to go somewhere off the beaten track."
