You should be aware of any live issues which may affect the transportation of ballot boxes to the verification venue, for example severe weather or road closures, and will need to decide what contingency measures are appropriate. You will need to monitor the situation on polling day and be able to take operational decisions to deal with situations as they may arise, such as vehicle breakdown. You will also need to decide what communication protocols will be for drivers to alert you to any delays.
Queues at the close of poll
The provision to allow those in queues at the close of poll to cast a vote could potentially cause delays if polling stations are operating beyond 10pm. You need to decide what mechanisms you are going to put in place to minimise any delays should this situation occur. You should also have in place communication protocols so that you can be immediately alerted in the event of queues arising. This will enable you to make an early assessment of the likely delay and adjust the verification as necessary, for example by re-allocating resources.
