Last year the figure was 336 but that fell to 115 in the same period this year.
States police chief Graham Power denied that there was any link between the figures and the decision to scrap the police motorbike unit.
However, the former States police motorbike officer and now States Deputy, Ben Fox, says he is concerned by the figures and intends to ask questions in the States of Home Affairs Minister Wendy Kinnard.
He might even bring a proposition for the motorbike unit to be reinstated, depending on the answers Senator Kinnard gives.
Deputy Fox said: ‘I would suggest that for road safety reasons alone we need the motorbikes back – not necessarily as big as before, but similar to those we saw on our TV screens darting all over London at the time of the 7 July bombings last year.
‘In my day our motorcyclists provided a multi-purpose use.
Maybe we could go back to providing such a use for the Island’s benefit.’ But Mr Power said that when the motorbike unit was scrapped the number of people reported for speeding increased.
He said a diversion of officers to police the streets at night combined with a reorganisation of the shift system had been the main reason for a fall in the number of motorists reported.
