More than eight out of 10 women can feel nervous while driving alone, according to a new poll by the AA.
Some 82% of female respondents admitted feeling "some degree of fear while driving alone".
The survey, which polled 3,000 people in July, also found that Limerick drivers were most likely to lock their doors when driving through particular areas, with Dublin drivers the second most likely.
The results of the poll also revealed that the over-65s are the most confident when driving alone.
Miriam O'Neill from the AA said that a series of high-profile carjackings over the summer have made people nervous.
"There was a cluster of event in May and as a result people do seem to be that bit more apprehensive," she said.
"Not surprisingly, women reported a slightly higher degree of anxiety over the potential risk, but that's not to say that the males that we polled [did not admit some anxiety].
"Actually, 77% of men said that they would lock their doors as a precaution if they felt they were driving through a dangerous area, so I think everyone is that little more vigilant."
