True or False: You should activate your turn signal at least 5 seconds before passing on freeways.

Activating your turn signal at least 5 seconds before passing on freeways is a safe and responsible practice. This timing gives other drivers sufficient notice of your intent to change lanes, which is crucial for maintaining safety on high-speed roadways. By signaling well in advance, you provide ample time for vehicles around you to adjust their speed or position if necessary. This helps prevent accidents, as sudden lane changes without signaling can lead to collisions.

Using your turn signal is not just a matter of courtesy; it's also a legal requirement in many jurisdictions, including California. Failing to signal your intentions can contribute to dangerous driving situations and may result in traffic violations. The other options, such as signaling only at night or in heavy traffic, do not encompass the importance of signaling in all driving conditions, particularly when it comes to freeway driving, where vehicles often travel at higher speeds.
