The most dangerous day to be on the road is Friday, 18 January, according to car insurance provider Admiral.
The insurer says Sunday is least common day for car accidents
After analysing 1.8 million claims received over the past 15 years, it has identified the days when accidents are most likely to occur.
Historically, more accidents happen on 18 January than any other date in the year, while Friday is the most common day of the week for crashes.
Unsurprisingly, the date with the least reported incidents is 29 February.
According to Admiral's research, the next safest dates are 25 and 26 December, when the roads tend to be very quiet.
For the same reason, the report highlights Sunday as the days of the week when accidents are least likely to occur, followed by Saturday.
The vast majority of problems happen on weekdays when the roads are busier.
TEN WORST DAYS FOR DRIVING

5. 20 July
6. 1 October
7. 21 October

"It's not surprising to see that the worst day of the week for accidents is a Friday," said Admiral managing director, Sue Longthorn.
"People are tired after a long week at work and can easily get caught up thinking about their weekend plans instead of the road ahead."
But she said it was less clear why there was such a concentration of incidents on 18 January.
"It could be that people have a lot on their mind as they haven't been paid for a while, the bills are coming in, it's dark, the weather's often foul and the fun of the festive period is a long and distant memory," she added.
And she warned drivers not to be complacent on 29 February 2008 as this leap year the extra day falls on a Friday.
