A75, 23/12/2017.

Driving on A75 Westbound towards Dumfries and was overtaken on double white lines by a Sawyers truck. Please can you mention that a single carageway road in Scotland is 40MPH in an HGV and not 50MPH as I know plenty of HGV drivers aswel as car drivers are unaware of this.


The speed limit for vehicles over 7.5 tonne is still 40mph on single carriageways in Scotland. When the speed limit was increased to 50mph for trucks on single carriages back in April 2015, it only applied in England and Wales.
