Final answer:
The safest hand positions on the steering wheel are at 9 and 3 o'clock or 8 and 4 o'clock. These positions offer better control and are safer in vehicles with airbags.
Step-by-step explanation:
The recommended position to place your hands on the steering wheel when driving is at 9 and 3 o'clock or at 8 and 4 o'clock. This guideline has evolved from the traditional 10 and 2 position due to changes in steering wheel design and safety enhancements like airbags. The 6 and 12 o'clock position is not recommended for driving as it provides less control and can be dangerous during airbag deployment.
