In reply to napoleon_dynamite:
Yes, still enforced, for crags above the road during daytime hours on Bank Holidays (until 6pm). Bouldering at Parisellas and routes at Mumbo Jumbo is ok though. Check the BMC RAD if you're not sure. Rockfall does land on the road every now and again, though usually not due to climbers activity.
Crags below the Marine Drive are ok for BH restrictions, but subject to tides and some nesting restrictions:
