Eamonn McPolin has taught Motor Vehicle and Road User Studies at GCSE for more than 20 years and is the chief examiner for the subject.
He is hoping that the funding for the GCSE being reinstated will mean more schools will introduce it.
"The funding will allow schools to purchase a moped which is needed to teach the practical aspect of the subject," he added.
"It very much focuses on vehicle control and road user behaviour which is essential life skills for pupils as they take to the roads."
Mr McPolin said he had been concerned that the cut to funding to schools for the GCSE meant that "road safety would suffer".
"If you don't have the practical aspect of the subject it loses its appeal for the students," he said.
"It is a two-year course, and the content does very much focus on road safety situations.
"This is one way of getting that very strong road safety message out through this subject."
Funding to schools for road safety workbooks and calendars were also cut by DfI in 2023.
