Bus services across Lewis and Harris are being reviewed by Comhairle nan Eilean Siar with a view to reducing their costs.
And users are being asked to say what they think from today (Monday December 3).
The Council says: "In recognition of the need to find nearly £10m of savings over the next four years the Comhairle agreed a service redesign programme as part of the 2018/19 Budget in February 2018.
"The service redesign programme has identified a wide range of Comhairle services that need to be redesigned to achieve the target savings and Transportation Services, including bus travel, is included in this process.
"The Comhairle realises the importance of consulting with bus service users and this survey is designed to get feedback on the demand for bus service routes and timetables as well as the reason for travelling.
"The Comhairle would appreciate your time completing this short survey as the results will help to influence the outcomes of any service redesign changes in advance of new bus contracts being awarded in 2019.
The survey will run from Monday 3 December to Saturday 15 December 2018.
"Paper copies of the survey questionnaire are available at Stornoway Bus Station, Stornoway Town Hall, Stornoway and Tarbert Libraries, Stornoway and Tarbert Comhairle Offices and on main bus services.
Completed questionnaires can be returned to any of the above locations.
