What should you do to signal for assistance on the freeway?

Using your hazard lights is an effective way to signal for assistance on the freeway, as they serve as a warning to other drivers that you may be in need of help. Hazard lights indicate that your vehicle is stationary or experiencing an issue, making it clear to others on the road that caution should be exercised.

While honking the horn can draw attention, it is typically used to alert other drivers of potential danger rather than to call for assistance. Waving your arms out the window may attract attention, but it is less effective than using your hazard lights, which universally convey your need for help.

Signal for assistance should involve strategies that prioritize safety and clear communication, making the use of hazard lights the most recognized and prudent choice in many emergency situations on the freeway. Combining various signaling methods, such as the ones mentioned, can effectively enhance visibility and increase the likelihood of receiving help, which is why the collective approach is echoed in the correct answer.
