What should always be turned on after starting the engine unless the car has daytime running lights?

The headlights should always be turned on after starting the engine unless the car is equipped with daytime running lights. This practice is essential for maintaining visibility on the road, making your vehicle more detectable to other drivers, especially during low-light conditions such as dawn, dusk, or in poor weather. Using headlights not only helps you see the road better but also enhances your visibility to others, reducing the risk of accidents.

Some vehicles come with daytime running lights that automatically turn on when the engine starts, which provides similar visibility benefits without needing to manually turn on the headlights. However, if your vehicle does not have this feature, it is critical to remember to activate the headlights to ensure safety at all times while driving.
