I do not recognise some of the sentiment that is behind Liam Kerr’s questioning. The Government has invested more than £250 million in maintenance and road safety on the A90 alone since 2007, so it is not true to characterise investment from the Government in that way.

However, I recognise Liam Kerr’s interest in the route and long-standing concerns about road safety. It is worth saying that some additional safety measures have been introduced, including vehicle-activated signs. More broadly, he will be aware that, along with Aberdeenshire Council, Nestrans has recently confirmed to Transport Scotland that it intends to take forward its own study of the A90. Of course, ministers will consider that in detail.

I reassure Liam Kerr that there are requirements to improve road safety on the trunk road network through STPR2 recommendation 30, which looks at provisions on improving road safety more broadly.
