Deaths were at their highest number in half a decade.
Some 24,620 people were killed or seriously injured over the past 12 months, according to the Department for Transport’s reported road casualties report.
This was compared to 23,914 the year before.
Campaigners have called for motorists to take “more care on the roads” and re-familiarise themselves with the Highway Code.
Deaths on UK roads increased by 2% to 1800, the highest number since 2011.
The number of deaths on UK roads during the second quarter of the year alone rose 7% on the previous year to 450. In the same period the number of killed and seriously injured casualties went up 3% to 44,250.
Road safety trainer the TTC Group said the increase in road deaths could be due to more drivers making “fatal mistakes”.
Director Alan Prosser said more people should re-read the Highway Code. “Sadly people are making fatal mistakes on the road leading to unnecessary deaths and serious injuries which could be avoided if we all took more care on the roads,” he said.
Road Safety Minister Andrew Jones said: “Britain continues to have some of the safest roads in the world but we are determined to do more.
“We have tightened the laws on drug driving, announced tougher penalties for using a mobile phone while driving and are also educating people about the consequences of dangerous driving through our THINK! Campaign,” he added.
Drivers caught using a mobile phone behind the wheel will no longer be able to take a course to avoid getting points on their licence under tough new Government plans.
Currently the first time a driver is caught using a mobile phone illegally they are given the chance to take a remedial course as an alternative to points.
It is hoped the crackdown will save lives as last year some 16,900 drivers across England and Wales were issued with fixed penalty notices for using a phone – a 43% decrease on the previous 12 months.
But DfT figures show mobile phone distractions were a factor in 440 accidents in Britain over the same period.
RAC road safety spokesman Pete Williams said: “It is time for motorists to accept their personal responsibility to drive safely and to observe the law. No call, text, post or tweet can be that important – it really can wait.”
