With particular attention to this...
Fans will be permitted into the Northamptonshire circuit’s huge grandstands from lunch time to watch the day’s traditional afternoon test session, when the BTCC’s teams and drivers go up against one another for the first time this year.
Paddock access will also be granted to spectators during the afternoon, offering fans a first opportunity of 2007 to hunt out autographs and photographs of their favourite BTCC stars. In addition, Rockingham has confirmed its diner will be open at lunch time for fans.
However, on safety grounds, access to pit garages and the pit lane is strictly forbidden. All public must stick to designated areas.
So don't get there too early!
