**Carelessness at the wheel** is one of the main causes of traffic accidents. This occurs when the driver is distracted by elements not related to driving, such as using a mobile phone or looking at a shop window. These distractions can be both internal, within the vehicle, and external, on the road.

- **Road-related distractions**: These can be caused by overconfidence from being familiar with the road, poorly visible traffic signs, complicated traffic situations, or reduced visibility conditions, such as at night or being dazzled by the lights of other vehicles.

- **Driver distractions**: These include personal factors such as fatigue, stress, alcohol or drug consumption, and certain behaviors like smoking, using a mobile phone, or eating while driving. These actions divert the driver's attention and can lead to accidents.


A clear example is **smoking while driving**, which doubles the risk of accidents. This is because the driver does not pay enough attention to the road, has one hand occupied, and the cigarette smoke can reduce visibility and air quality inside the vehicle, affecting driving abilities.

Therefore, carelessness at the wheel can cause a large number of accidents, as distractions directly affect the driver's ability to react appropriately to traffic conditions.
