Police are appealing for help to identify a rider who left behind more than just skid marks after failing to stop for Police in Stoke today.

The rider was seen on a green dirtbike travelling on Main Road Stoke about 11.20am without a helmet and without a visible number plate. When signalled to stop by Police, the rider allegedly failed to do so.

Community Constable Daryl Fenemor from Tasman Police says that during the incident, the rider allegedly pulled a wheelie before losing control of the bike, crashing and sliding along the road.

Police are urging motorists to carefully consider how long alcohol can remain in their system following routine traffic stops in Southland today. 

Two drivers, one of which was in a school zone, underwent evidential breath testing (EBA), after they were stopped by Police this morning for exceeding the posted speed limit. Both blew over the legal alcohol limit. 

Both drivers admitted to drinking alcohol the night before, but got behind the wheel this morning, incorrectly assuming that it had cleared their system already.
