When passing a large commercial tractor-trailer in strong crosswind conditions, a passenger vehicle driver should expect an initial lateral force pushing their car away from the truck while alongside the trailer, followed by a pulling force toward the truck as they clear the front bumper.
Answer: Answer
Answer
The statement is false. While traveling alongside a large truck's trailer, the truck acts as a windbreak against crosswinds. Once the passenger car clears the front bumper of the truck, it encounters a sudden outward lateral force pushing it away from the truck due to exposed crosswinds and air displacement.
The statement is false because a large commercial tractor-trailer acts as a windbreak while a vehicle is traveling alongside its trailer, shielding the passenger car from crosswinds. Upon clearing the front bumper of the truck, the passenger car suddenly leaves this protected zone and encounters a powerful outward lateral blast created by unshielded crosswinds and front air displacement from the truck cabin.
