You only have to disclose the unspent speeding convictions i.e, any that are not yet Five years old, the speeding convictions that are older than Five years are spent...therefore you do not have to mention those.
The TT99 was a disqualification therefore as you were disqual for Six months, under the ROO act you only have to disclose that for Six months from the date you received it, providing at the same time of conviction you were not given a longer penalty for anything else.
Disqualifications extract rom the ROO act.
The rehabilitation period for a disqualification is the length of the disqualification. If a person is disqualified at the same time as receiving another penalty, the longer rehabilitation period applies. (For example, if a motorist is banned from driving for seven years and fined - which takes five years to become spent - the rehabilitation period would be seven years, not five years.)
