Labour councillor Kevin Lalley has expressed his concerns that people, men in particular, needed more encouragement to look after their physical health.
The council has been rejecting a large number of private hire applications due to its overprovision policy, but drivers affected warned people were already struggling to get taxis late at night.
It comes after a high volume of unplanned emergency works, recently undertaken within the Dumbarton area, resulted in a significant impact on traffic on local roads.
