What action is required if visibility is significantly hampered while driving?

If visibility is significantly hampered while driving, the safest action is to pull over safely and wait for improved visibility. This approach prioritizes the safety of the driver, passengers, and other road users. Continuing to drive without clear visibility poses a significant risk of accidents, as the driver may not be able to react appropriately to obstacles, traffic signals, or other vehicles.

By pulling over, the driver not only mitigates the risk of a potential incident but also provides an opportunity to assess the situation. Staying off the road until conditions improve ensures that the driver remains in control and can safely resume travel when conditions are deemed safe. This action is particularly important in areas where weather conditions can deteriorate rapidly, affecting visibility.

The other options suggest either continuing to drive despite poor visibility or doing so at a reduced speed, which may still lead to dangerous situations. Utilizing hazard lights while driving slowly could alert other drivers, but it does not eliminate the dangers posed by low visibility while actively navigating the road. Ultimately, waiting for conditions to improve represents the most prudent course of action.
