Truck parking Glasgow to Aberdeen

Realistically taking a 10 hour drive from Dawlish I’d say your best bet would be Muir Park Truckstop just south of Stirling. Small, no frills place but safe.

Come off the M80/M9 at Stirling Services and follow the A91 east for 1 mile to the first roundabout. There, turn right on to the A9 south towards Cowie and Larbert and the Truckstop is a couple of hundred metres along on your left.
