The five most dangerous trunk roads in Scotland have been revealed.

Between 2013 and 2015, 897 people were seriously injured or killed on Scotland's trunk and motorway road network.

The number of fatalities and injuries on the trunk road network differed wildly across the country.

While the A889 from St Andrew's to Loch Leven did not have a single injury in the period, others had scores of drivers and passengers inured.

Here are Scotland's most dangerous trunk roads:

Thirty people were killed while driving along this major road artery between 2013 and 2015.

A further 83 people were seriously hurt on the route.

The road runs from Fraserburgh in the North East down the east coast before becoming the M90 and reemerges and over the Forth Road Bridge to Edinburgh.

One of those to lose their lives on the road was 9-year-old Kairon McKay who was playing beside the busy trunk road with his new toy skateboard.

His mother, Laura McKay, told the Sunday Post newspaper of the moment she found out her son had died when when a distraught police officer chapped on her door.

She said: "I could see the woman officer had been crying and I knew something terrible had happened," she said.

"My world ended at that point and I am still struggling to believe Kairon has passed away".

The A9 is Scotland's longest road and is notorious for its accidents.

Over the last three years 19 people died on the road while a further 48 people were seriously hurt.

To try and improve the road's safety record the Scottish Government has in recent years installed average speed cameras along a significant stretch of the road as well as upgrading parts of the trunk road to a dual carriageway.

It runs from Thurso to Falkirk through the centre of the country.

Heavy snowfall often is a hazard on this Aberdeen to Inverness trunk road.

The road experienced more serious injuries in this period than the A9.

A total of 55 people were seriously injured while using the road while a further seven people were killed.

In February, 2016 four people were seriously hurt in a head on collision. One passenger, a 29-year-old male, had to be airlifted to Raigmore hospital from the scene near Moray to Inverness.

The beautiful views the road offers masks the dangers which it brings.

Starting just west of Glasgow, the road winds northwards to Glencoe offering Glaswegians an escape to Loch Lomond or the West Highlands.

Despite its beauty the road is deadly. Fifthteen people were killed while travelling on the route, while a further 42 people were also seriously injured.

Due to the road's rural location in parts crashes can cause major delays.

In February, an overturned lorry and van caused a 70 mile diversion for drivers.

It's not only other motorists that drivers have to watch out for on the A85.

In 2004, a landslide covered a portion of the road stranding motorists.

Over the last three years 11 people have died on the road and the same number of motorists being seriously injured as that on the A9, 44.

The road stretches from Perth to the Loch Lomond and the Trossachs National Park.

The figures were disclosed by the Scottish Government to the Scottish Liberal Democrats in a written answer by transport minister Humza Yousaf.

Lib Dem MSP Mike Rumbles says the figures show the Scottish Government have "still has a huge amount of work to do".

Rumbles said: "Most families rely on their cars to get around and we need to ensure that we do what we can to make our roads as safe as possible. These figures demonstrate clearly that the Scottish Government still has a huge amount of work to do to boost safety on the trunk roads that are directly under their control.

"Since 2013 we have seen year on year increases in the number of serious or fatal accidents on trunk roads under the management of the Scottish Government. We have also seen transport infrastructure projects that have already been budgeted for and announced with great fanfare being dragged out and delayed.

"Our emergency services do fantastic, life-saving work responding to accidents as they happen but they need the government back them up too.

"Clearly, major infrastructure projects take time. But we have already been waiting for years to see improvements to roads like the A96. The SNP came into government in 2007 pledging urgent action to improve these trunk roads but next to nothing has happened."

A Transport Scotland spokeswoman told STV they are "committed" to working to reduce casualties on Scotland's roads.

She said: "Every road death is a tragedy - that is why we are committed to working with local authorities and other key partners to deliver the priorities and casualty reduction targets set out in Scotland's road safety framework to 2020.

"Any suggestion fatal casualties are rising is quite simply incorrect. Scotland has some of the safest roads in the world and figures published in mid-June show we have the lowest casualty figures nationally since records began. In fact, the data for the five roads highlighted clearly shows a reduction of 16% in fatal accidents over the three years quoted. Not only this, these roads are the longest, with large traffic volumes on some sections, and the true casualty reductions should be welcomed.

She continued: "Separately, there has been an improved A9 road safety performance since the installation of the average speed cameras with road deaths down 30 per cent, seriously injured down over 70% and fewer incidents disrupting traffic - all this against a background of increasing traffic volumes and improved journey time reliability.

"Our ambitious programmes to dual the A9 and A96 will bring faster journey times, better journey time reliability and road safety improvements for anyone travelling on these important routes. We are also delivering improvements in the north east through the AWPR/B-T scheme. Beyond this, the Scottish Government has invested over £1.3bn in maintaining the motorways and other trunk roads since 2007, with road safety spend aimed at pursuing reductions in both accidents and casualties to support the delivery of our 2020 Road Safety Framework targets."
