The government has approved the used of a saliva kit that can test for traces of illegal drugs in the bloodstreams of drivers, opening up a new war on suspiciously wobbly and carefree car owners this Christmas.
The saliva tests can give police an indication whether a driver has taken cocaine or cannabis, with a positive result seeing the driver taken in for more detailed blood tests by doctors to confirm the exact quantities. Now they've been approved for use, forces could start using them on the roads within days.
The Department for Transport estimates that 200 road deaths per year are caused by drivers on something other than just the road. [BBC]
