Ch. 5 · Driving Method

When changing course to the right while continuing in the same direction, you must give a signal about 5 seconds before changing course.

[True / False · Medium]

Answer: ✕ False

Explanation

According to the signal table in the Rules of the Road, when changing course to the right while continuing in the same direction, you must give a signal "about 3 seconds before changing course." The correct timing is about 3 seconds, not 5 seconds, so this statement is incorrect.

Three seconds is the sweet spot: enough warning without signaling too far in advance.
