If you do not want an additional detail field to be displayed when setting vehicle routes, you can inactivate it or delete it. However, you cannot delete an additional detail field that has already been used to record vehicle route information.

At the top of your dashboard, click the module access icon > Administration > Transport > Manage vehicle additional details to open the Manage vehicle additional details page.
