Tracking shots
Tracking on public roads can only be done with the
permission of the police. Tracking shots (car-to-car) can
only be done from a specially modified tracking vehicle,
or from an estate or hatchback with the tailgate locked
and secured in the ‘up’ position. The police will not
normally allow this on public roads. Tracking in this
manner is only permissible on closed roads or private
land once the risks have been assessed and controls
put in place.
The camera operator should be seated with a seat belt
on. Care must be taken to ensure no loose objects will
fall out of the moving car - the camera and any other kit
must be secured with a safety line.
Tracking must not be done from the boots of saloon
cars, or from any open doors.

The use of standard vehicles where filming is done through an open window and all the equipment is kept within the confines of the vehicle is not a major issue. It is important that the operator and their camera are secure in the vehicle. However filming from a moving vehicle when the operator is doing so through a raised tailgate or boot lid (e.g. an Volvo or Audi estate) would not be endorsed by us as a safe method of filming on the highway unless the vehicle is approved by manufacturer as having no loss of body strength when driven with tailgates/doors open. We have yet to find a manufacturer who would provide this endorsement for standard hatchback/estate cars as they tend to have no chassis but rely on a monocoque style body shell, which relies on the doors all being shut etc.

However some large 4 x 4 vehicles such as the Range Rover, BMW X5, Volvo XC90, Nissan Pathfinder, Toyota Landcruiser etc. where there is a split tailgate and the upper glass portion can be locked up in a raised position and the lower portion closed shut, results in no loss of strength to the vehicle in the event of a collision (endorsed by Range Rover) and are therefore an acceptable solution. Additionally filming from a cabriolet/soft top car with the roof down is also an acceptable method and should give you an unobstructed 270 degree view to the rear.
