1. Night-Time Driving: Headlights should be turned on when driving during night-time conditions, which are typically considered to be between sunset and sunrise. This ensures better visibility for the driver, allowing them to see the road, obstacles, and other vehicles more clearly.
2. Low-Visibility Conditions: Headlights should also be used in low-visibility conditions, even during daytime. This includes situations like heavy rain, fog, snow, dust storms, or any other weather condition that reduces visibility significantly.
3. Tunnels and Bridges: Headlights should be turned on when entering tunnels or driving under bridges. These areas can be darker than the surrounding roads, so headlights improve the driver's ability to see.
4. Country Roads: When driving on unlit or poorly lit rural roads, it's advisable to use headlights to increase visibility for oncoming vehicles and pedestrians.
5. Adverse Weather Conditions: In addition to low-visibility conditions, headlights should also be used during adverse weather conditions such as heavy rain, snow, or strong winds.
6. Dawn and Dusk: During dawn and dusk, when the natural light is reduced, it's recommended to turn on headlights to ensure better visibility for yourself and other road users.
7. Parked on the Roadside: If a vehicle is parked on the side of the road in low-visibility conditions or at night, it's important to keep the headlights on to make the vehicle more noticeable to other drivers.
It's generally advisable to use headlights whenever driving in conditions where visibility is reduced or compromised, regardless of the time of day. Headlights help enhance the visibility of the vehicle to both the driver and other road users, contributing to safer driving conditions for all.
