Which road users are most likely to be affected by the turbulence created by large vehicles travelling at speed?

Explanation: Caravans are relatively light but have a large surface area. This makes them vulnerable to the turbulence created by large vehicles travelling at speed. The blast of air can destabilise the caravan, causing it to snake, and in extreme cases they can be blown over.
