Why should other drivers, and the driver of a doubles or triples combination, both be extra cautious around this type of combination in crosswinds?

Pick an answer

1. Only single trailer combinations are affected by crosswinds
2. Crosswinds have no meaningful effect on multi-trailer combinations of any length since the tractor is assumed to block the wind from reaching any of the trailers behind it
3. The combination's length and surface area make it more prone to being pushed or swaying in strong gusts, which can affect nearby traffic
4. Crosswind effects apply only to the tractor, never the trailers
