Carnegie thinks the solution to this problem doesn't really require rocket science.

"A working group has recommended that barriers be installed on the Forth Road Bridge to stop lorries blowing over. The group was set up by the Forth Estuary Transport Authority (Feta), which manages the bridge, after several incidents during high winds. CCTV images of drivers who persistently cross when HGVs are banned could also be released to try to catch them."

The cops should charge the lorry drivers that cross the Bridge after ignoring repeated warnings and fine them for driving without due care and attention, and keep doing it until the ones that are ignoring the message get it.
