Foreign drivers in Scotland are being urged to purchase 'T-plates' after warnings Highland pile-ups caused by people being unused to driving on the left side of the road have surged by almost 50 per cent.

The signs, which are in the same style as learner or recently passed plates - known as L-plates and P-plates - feature a large green letter T with the word 'tourist' written beneath.

Creator Robert Marshall, a hotelier from Kingussie, first created the plates after his own stressful experience of driving in Tenerife.

They are designed to let other drivers know those ahead of them may be unfamiliar with the roads and require more time or patience.

It comes after Transport Scotland revealed in May that the number of crashes caused by 'inexperience of driving on the left' rose by 46 percent in just one year.
