Which of the following is part of maintaining a driver's safety?

Maintaining a driver's safety is heavily influenced by the choices made while operating a vehicle. Avoiding drug use while driving is crucial because drugs, whether they are illegal substances or prescription medications, can significantly impair judgment, reaction times, and overall decision-making ability. By choosing to drive sober, a driver is more capable of making safe choices while on the road, recognizing hazards, and responding appropriately to unexpected situations.

The other options do not contribute directly to enhancing a driver’s safety in the same manner. Window tinting may provide comfort from sunlight and potentially increase privacy, but it can also obstruct visibility if not done appropriately. Using navigation systems can make travel easier but does not inherently improve safety if it causes distractions. Driving with headlights off poses a serious safety hazard, particularly at night or in poor visibility conditions, increasing the risk of accidents. Therefore, avoiding drug use while behind the wheel is pivotal for ensuring one's safety and the safety of others on the road.
