Motorists find tailgating the most annoying habit on roads, according to a new survey.
A poll by automotive repair company Kwik-Fit found that women were more irritated by tailgating than men.
Failing to indicate, dangerous overtaking and jumping lights were the next most-disliked road habits.
The list of top 10 hates, based on a survey of more than 1,000 adults, also included lane hogging, last-minute braking, hesitant driving and "undertaking" - overtaking on the inside.
Male drivers were found to be more frustrated than females over dangerous overtaking, hesitant driving or lane hogging.
Kwik-Fit customer services director David White said these habits pose a serious danger to fellow drivers and many car accidents are caused by aggressive behaviour on roads.
He added: "Motorists need to remember that these aren't just annoying, they put the safety of all road users at risk.
"In our study only 2% of motorists said that nothing annoyed them on the road, which shows that the vast majority of us can make big improvements in our driver styles and contribute to calmer, and safer, roads."
