Where is it allowed to use headlights to signal the intention to pass during daytime?

1. City limits

2. Outside city limits

3. Only in residential areas

4. All locations

The correct answer is: Outside city limits

Using headlights to signal the intention to pass during daytime is primarily allowed outside city limits. This practice is common in rural areas or on highways where the speed limit is higher, and visibility is crucial for ensuring safety when overtaking. In these areas, drivers may use their headlights to alert other drivers of their intention to pass, which can help prevent potential misunderstandings and collisions, especially when visibility is limited due to curves or hills. In contrast, within city limits, the use of headlights in this manner is less common and can often be avoided due to the higher density of traffic, intersections, and pedestrian areas where clearer communication is established through other means, such as turn signals and vehicle positioning. While signaling intentions with lights may be used in various situations, the safest and most appropriate context for using headlights as a passing signal is outside of densely populated areas where the likelihood of needing to pass or alert others is increased.
