If you observe a drowsy driver, what is the best action to take?

The best action to take when you observe a drowsy driver is to find a safe place to stop or ask a passenger to call law enforcement. This approach prioritizes safety for everyone on the road, including the drowsy driver. By stopping in a safe location, you can assess the situation further without endangering yourself or other road users.

By having a passenger contact law enforcement, you ensure that trained professionals are informed about the potentially hazardous driving behavior. This allows law enforcement to intervene appropriately, potentially preventing accidents caused by drowsiness.

Other options would either fail to effectively address the danger, such as simply following the driver or using your headlights to signal them, which do not mitigate the risk being posed on the road. These methods cannot ensure immediate safety and may even complicate the situation. Thus, finding a safe stopping point and contacting authorities is the most responsible and effective response.
