Which action is not part of the recommended routine for safely backing a vehicle?

Correct answer: C – Sounding the horn every time before backing
Before backing, check behind the vehicle for children, objects, or other hazards that may not be visible from the driver’s seat. Use both mirrors and head checks, move slowly, and continue looking rearward until stopped. A horn may sometimes alert another road user, but sounding it every time is not a substitute for verifying that the path is clear.
