What should be discouraged to ensure road safety for drivers?

To ensure road safety, it's essential to discourage actions that may put drivers or others at risk. Endangering oneself or others on the road encompasses a range of unsafe behaviors that can lead to accidents or injuries. This includes reckless driving, aggressive maneuvers, and failing to observe traffic rules, which all contribute to a hazardous driving environment.

While the other options also represent serious concerns—driving without a valid license indicates a lack of required qualifications and driving under the influence poses significant impairment—these specific actions fall under the broader umbrella of endangering oneself or others.

By focusing on the overarching principle of discouraging any behavior that might jeopardize safety, we can highlight the importance of responsible driving and the collective responsibility of all road users to maintain a safe environment for everyone.
