Heavy traffic, delays and lack of skills mean up to one in five drivers loathe the M-way network.
The findings form part of research by AA Driving School which reveals that fear of motorways and a lack of driving skills are causing millions of Britons to avoid the roads altogether.
Nationally, one in seven motorists – nearly five million in total – say they lack skills needed for motorway driving.
Simon Douglas, AA Driving School director, says: "The evidence suggests motorways are our most feared and avoided roads, yet statistically they are safer than the alternatives.
"Tailored motorway tuition with a fully-qualified instructor can help build the skills and confidence to drive safely and get the most out of our motorway network."
