How should a driver react to a sudden obstacle in the road?

Answer: B — Assess total space and either steer around it or brake firmly if necessary

The optimal reaction to a sudden obstacle in the road is to assess the situation thoroughly before taking action. By evaluating the total space around you, you can determine whether it’s safer to steer around the obstacle or brake firmly to avoid a collision. This approach takes into account not just the immediate obstacle but also other factors such as surrounding traffic, road conditions, and the behavior of other vehicles. Steering around an obstacle can often be a more effective and safer choice than coming to a sudden stop, especially if stopping might lead to a rear-end collision from other vehicles. Additionally, the option of accelerating quickly could exacerbate the danger by increasing the risk of losing control or crashing into other objects. Sounding the horn may alert other motorists but doesn’t directly address the immediate need to navigate the hazard safely. In summary, the correct answer involves a reasoned assessment that prioritizes control and safety, allowing the driver to make an informed decision based on the circumstances at hand.
