Commenting on the findings, Dan Hutson, head of motor insurance at, said:

Having a quick reaction time is key to being a responsible driver, and you need to be aware of the conditions around you and be able to respond to them in time. It’s interesting to see from our research that drivers have different reaction times depending on the weather condition, with fog and snow affecting them the most. 

“The Highway Code sets out in its advice for driving in bad weather, that - you should make sure you’ve always got time to react to a potential hazard by keeping your distance from the car in front. Tailgating is illegal and should never be done in any weather condition, but you should always allow for bigger gaps between you and the car in front of you in more difficult weather conditions. 

“It’s also important to carry out correct vehicle checks before setting off on a long journey and make frequent stops too. Another tip is to have regular eye checks to ensure you meet the minimum eyesight standard for driving.”

  1. Survey of 1,000 UK drivers undertaken in July 2020 by TLF


Via comparethemarket’s interactive quiz, respondents were first asked, in seconds, how long it took them to spot the hidden objects in normal weather conditions, and then in bad weather conditions. Once we had the responses, we then worked out the percentage increase for each different weather condition to determine just how much reaction times are impacted.
