SQL JOIN QUERY ISSUE

having problem with query below

SELECT DISTINCT dbo.logon.DRIVER_NO, dbo.booking_form.DriverNo FROM
((dbo.logon RIGHT JOIN dbo.Employees ON dbo.logon.DRIVER_NO =
dbo.Employees.DriverNo) ) LEFT JOIN dbo.booking_form ON dbo.logon.DRIVER_NO
= dbo.booking_form.DriverNo

problem is it produces more than 1 result for the driver from the
booking_form table. If a Driver is logged in then I need to show information
from the booking_form table for that driver but it produces row after row of
data. Have tried all combinations of JOIN but to no avail. Code:
