Racing in the Isle of Man TT could be extended to cover two weekends from 2023, the Enterprise Department (DfE) said.
A consultation has been launched on the proposed changes to the days and times when public roads are closed to host the event.
The TT was canceled for two consecutive years due to the coronavirus pandemic.
A spokesperson for the DfE said the changes were aimed at creating “growth” in the audience.
Although potential road closures for the event will remain unchanged for the 2022 event, plans are in place for a redesign the following year.
As the race takes place on public roads, the organizers must obtain a road closure order for the event to take place.
The proposals would see the races take place on Saturday and Sunday at the start of the race week instead of Saturday.
Likewise, the following Saturday would be used as a showcase for the Senior TT race, which typically takes place on Friday, a public holiday known as Senior Race Day.
According to plans, the holiday would remain in place with two more races taking place on the same day.
Other changes include the action that typically takes place on the Monday of the race week being moved to Tuesday, providing two consecutive race days.
Conversely, the first practice session would move at the end of the May bank holiday from its traditional home from the previous Saturday.
A DfE spokesperson said attendance at the event had “started to level off” as visitor growth was “limited by travel and accommodation capacity”.
Increasing the number of racing days from four to six and condensing the races held during the work week by adding a second weekend would meet visitors’ desire to spend a long weekend on the island, he said. added.
The event usually takes place during the first two weeks of June each year.
A consultation on the proposed changes is available online until July 2.
