Which of the following can help prevent drowsy driving?

Getting adequate sleep before driving is essential in preventing drowsy driving. Proper rest allows the brain to function optimally and maintains alertness while driving. When a person is well-rested, they are more capable of making quick decisions, reacting promptly to changes in traffic conditions, and staying focused on the road. Sleep deprivation, on the other hand, significantly increases the risk of fatigue-related accidents, impairing judgment and reaction time similar to being under the influence of alcohol.

While options like listening to loud music and driving with the windows down can provide temporary stimulation or relief from a monotonous driving environment, they do not address the underlying issue of fatigue. Similarly, consuming high caffeine drinks may provide a short-term boost in alertness but does not replace the need for adequate sleep and can lead to a crash in energy levels afterward. Therefore, ensuring that one has had enough sleep is the most effective and reliable method for preventing drowsiness while driving.
