The Isle of Man Post Office has announced details of changes to its delivery and collection services ahead of TT week.
From Saturday, May 31 to Friday, June 6, on race days, deliveries to addresses on the course, or where access is only possible via the course, will be significantly affected.
For areas that are inaccessible because of road closures, deliveries may take place on the day after the scheduled races.
If any races are delayed, the Post Office will endeavour to deliver to these addresses prior to the roads closing on the succeeding day.
It will also try to maintain normal collection times where possible, however is asking the public to be aware of potential disruption.
High traffic volumes may also cause delays.
On non-race days there will be a complete delivery of mail but there is a possibility of some delay, as deliveries will include mail which was not able to be delivered the previous day.
Addresses within the TT course, that are affected by the road closures, will shortly receive a letter from the Post Office explaining the specific arrangements and offering them the option to collect their mail from their local delivery office or make alternative arrangements.
Postal staff will be wearing high visibility jackets whilst they carry out their deliveries during TT Week to ensure that motorists can clearly see them on the road.
All post offices will be open as usual during TT week including Senior Race Day (June 6), except those located on the race course and post offices will be closed on Bank Holiday Monday, May 26.
The Department of Social Care has agreed that the pensions and allowances due for payment on May 26 can be encashed one week early.
