More than one in four drivers would not take a break if they felt tired while driving, according to new research.
Car supermarket firm Motorpoint conducted a survey in which two-thirds of British motorists claimed to have been so fatigued they were close to falling asleep at some point in the last year.
The issue seems to be more of a problem than had been first thought, according to managing director of the company David Shelton.
"Drivers know when they are feeling sleepy, so making the decision to stay on the road is a real choice … The question is whether the people who drive on are underestimating the risks or simply ignoring them," he said.
Research carried out by road safety charity Brake in association with Green Flag earlier this year found that one in ten motorists had admitted to falling asleep in the last year.
