Final answer:
The most recommended hand position on the steering wheel for safe driving is the 9 and 3 o'clock position, offering optimal control and airbag safety. The 10 and 2 position is outdated due to airbag-related injuries, while the 8 and 4 provides a relaxed grip but less control, and the 12 o'clock position has significant safety drawbacks.
Step-by-step explanation:
The ideal hand position on the steering wheel for safe driving has been a topic of debate, but recent guidance and the standard set by many driving experts, including those from the National Highway Traffic Safety Administration (NHTSA), recommend the 9 and 3 o'clock position. This position is thought to give the driver the most control over the vehicle while also allowing for the optimal use and effectiveness of the steering wheel's airbag in case of a collision.
Previously, the 10 and 2 o'clock position was commonly recommended. However, due to airbag deployment mechanisms and changes in steering wheel design, this position can lead to more serious injuries in the event of an airbag deploying during a crash. The 8 and 4 o'clock position offers a more relaxed grip but may not provide the same level of control as the 9 and 3 position. Holding the steering wheel at the 12 o'clock position is not advised, as it can lead to a loss of control and could cause the driver's arms to be injured by the airbag's upward motion in the case of deployment.
