We very rarely "'arrest" for cancelled licence offences and our drink driving laws allow us to have an offender for this offence in custody without arrest, so as a traffic unit, I do not have many "lock ups" other than the occaisonal drunk/public order offence. Being in a rural area, the GD lads and lasses scoop them up pretty quick to keep thier own work rate looking acceptable. I also like to give them the rare drug offender ortea leaf that I run down. ( I am not seeking transfer or promotion at the moment and if I can help someone else look good then go for it I say.)
I can't find a way to let them do a fata crash investigation though.
