Motorcycle and classic car insurance broker Carole Nash obtained the data by submitting a Freedom of Information request to the Department for Transport.
The extensive analysis of over 2,000 British motorways and A-roads showed that although the A1 is the deadliest road, the A38 had the most accidents - 8,698.

Similarly, though the M6 is Britain's deadliest motorway, there were 331 more collisions reported on the M25.
The safest road in Britain was found to be the M49, in south-west England, where just 11 accidents occurred involving 9 vehicles and no fatalities were reported.
Rebecca Donohue, head of marketing at Carole Nash, said: "Safety is naturally paramount to every road user, so we hope this data and the road safety hub on our website will help provide our customers with as much information as possible to keep them safe.
"It is very positive though to note that the number of accidents is steadily decreasing year-on-year, which is testament to road users and those who enforce the safety precautions on our highways."
