Dear Mr Haylock FREEDOM OF INFORMATION REQUEST REFERENCE NUMBER: 000298/16
Thank you for your request for information regarding stinger devices which has now been
considered. Applicant Question:
Thank you for your very informative reply. As a follow up, could I ask for a clarification please, since
you have included only the executive summary of the report you mention?
Obviously the test rider in the tests as documented was aware that he had been over a Stinger
device, since that was the purpose of the exercise. Reading between the lines of the tests, it would
appear that in a real world scenario a rider would not necessarily be aware at the time that they
had encountered a Stinger, as opposed to for example a speed cushion or a raised manhole cover,
especially if he or she did so after dark. One finding of the testing appeared to be that the fact that
the tyres on a motorcycle had been deflated by a Stinger was not immediately obvious to the rider
if he or she was travelling at high speed in a straight line at the time.
This raises the possibility that a motorcyclist riding at night might discover that they have been
'Stung' only when attempting a high speed manoeuvre on two flat tyres, or only when a tyre
eventually falls apart or jumps partly off a rim and possibly jams a wheel.
1. Have I described a scenario here that NPCC or the report's authors have foreseen?
2. Is there anything in the fuller report designed to highlight, mitigate, eliminate or otherwise
manage the risk of motorcyclists not realising they have been stung & that their tyres are
deflating and thus unknowingly exposing themselves to risk of injury or death that they
wouldn't if they knew?
3. Can I also ask whether there is specific guidance about proportionality,
4. and about when in particular it is NOT appropriate to use a measure like a Stinger against a
motorcycle, and also whether for officers to be authorised to deploy Stinger against
motorcycles you recommend that they have special training to ensure that they are fully
conversant with any dos and don'ts that are specific to use against motorcycles?

Thank you again for your reply to date, I certainly found it reassuring to know that work had been
done in this area and that some of the risks I was most concerned about would seem at first sight
not to be as significant as I imagined they might be. NPCC Response:
