The RAC said a survey of 2,000 people showed that only 12% supported putting pubs into motorway service stations.
Around two-thirds said they did not agree with the move, with older drivers more likely to oppose the sale of alcohol at motorway service areas.
Only 8% of over-55s were in favour, with 71% against, while almost one in five of those aged between 18 and 34 were in support.
Around one in four of everyone questioned were undecided on the issue.
