What is a proper use of vehicle lights and flashers?

Using brake lights to alert other drivers of a sudden stop is a proper use of vehicle lights and flashers. This action helps communicate to drivers behind you that you are slowing down or coming to a stop, which is crucial for maintaining safe distances and preventing rear-end collisions. Proper signaling through brake lights ensures that other road users are aware of your intentions and can react accordingly, enhancing overall safety on the road.

In contrast, using high beams in foggy conditions can create glare that reduces visibility for all drivers, making this practice unsafe. Leaving headlights off during the day neglects an important safety feature, as headlights help make a vehicle more visible to others, especially in inclement weather or low-light conditions. While using turn signals to indicate lane changes is indeed important, they are necessary not just for lane changes but for all maneuvers involving direction changes, such as merging or turning. Thus, the emphasis on using brake lights for alerts is vital for driving safety.
