More than a hundred people lost their lives on Welsh roads last year and thousands more were injured.

The latest figures from the Welsh Government show there were 4,556 crashes in 2017 which left 961 people with serious injuries and took the lives of 103.

According to the Road Safety Foundation, Wales had the second highest rate of fatal and serious crashes per kilometre in Great Britain and the risk rate in Wales was nearly double than the West Midlands, which is considered the safest region.

But you might be surprised to find out the most dangerous road in the country was actually a six-mile road in north Wales.

Which roads had the most accidents?

The A470, which stretches more than 186 miles and connects Cardiff to north Wales, saw the most car accidents - and deaths - in 2017.

Just last week a stretch of the road near Abercynon was closed following a serious motorbike crash which left one man being taken to the University of Hospital Wales.

In October 2017, a driver died following a three-vehicle crash on the road .

Three vehicles were involved, including a HGV and Mr Griffiths was pronounced dead at the scene.

Last year, seven people died on the A470.

Here are the 10 roads that had the most accidents:

Road Number of accidents A470 238 M4 199 A48 181 A483 173 A40 136 A487 135 A4 84 A55 84 A465 61 A5 60

Here are the 10 roads that had the most deaths:

Road Number of deaths A470 7 A487 4 A40 3 A465 3 A48 3 A494 3 B4603 3 M4 3 A4 2 A4109 2

The M4 motorway, which runs between London and Wales had the second highest number of accidents. In the 12-month window, there were 199 crashes and three deaths in Wales.

In November 2017, a man died after being "struck by a number of vehicles" on the M4 between junction 35 Pencoed and junction 36 Sarn.

But which roads are the most dangerous?

According to the Road Safety Foundation, roads that see the most accidents aren't necessarily the most dangerous.

The foundation said that last year, the most dangerous road in Wales was the A5026 from Lloc to Whelton. Between 2013-15 there were eight fatal or serious crashes on the 6.3-mile road - 38% of which involved motorbikes.

In 2017, 12 people were injured in eight car accidents - although only person was seriously injured and nobody lost their life.

The foundation mapped Welsh roads and categorised them by their risk which is calculated by comparing the frequency of road crashes resulting in death and serious injury with how much traffic each road carries.

They found the six high-risk and most dangerous roads in Wales are:

A5026 from Lloc to Whelston

A5 from Bangor to Corwen

A5104

A496

A539

A4066

Despite the M4 having 199 accidents in 2017, it's actually considered one of the safest, with a low risk of accidents.

The A470 is also categorised as a medium risk road because of the amount of traffic that passes and the length of the road.
